ZSP404D dual range digital milligram balance is a high capacity
scale that can weigh, with little effort, to 1mg each and every time up to a 40 gram capacity and to 0.01 gram up to the 400 gram capacity. In
addition, it is a very hardy scale that is very resistant to damage or abuse.
Why settle for less with a foreign made product when you can have all this plus
be able to talk with the manufacturer right here in the USA
Scientech Zeta Series digital scales offer a revolutionary weighing technology
with a patent pending that no other balance manufacturer can match. This
weigh sensor found only in the Zeta Series offers a very fast response time
with excellent repeatability and linearity weighing results. Many of our
customers say that the Zeta models are quicker and far more stable than other
brand competitor's models implementing a lever designed weigh cell.
Many people call us with the question - what is the best balance to buy?
This is so simple now with the Zeta Series since it is all in the weighing sensor
design and the company that builds the balance.
Another deciding factor on selecting a balance to buy is issue is repairability.
Many of the balances on the market can't be repaired if you put an excessive
load on the weighing pan, but you can with Scientech and at a REASONABLE price.
High quality, high performance, and low cost, are the issues that make us say
Scientech offers truly a real value over all other brands.

Please note that the Zeta Series exclusively from Scientech has a weighing sensor with a suspension system which cannot be broken by customer abuse or by dropping a weight onto the weighing pan. As you might know, the highest failure mode for any milligram (1mg) balance is a broken suspension system due to them having fragile pivots, pullers, flexures, or bearings. Then when any weight is dropped on the weighing pan (this is called shock loading) or by user misuse, these fragile pivots, pullers, flexures, bearing will break. The way competitor brands try to handle this concern is to state that they have "overload" protections. However, overload protection does not protect against shock loading or customer abuse. Therefore, the damaged scale is not covered under warranty and you are forced to pay high repair charges.

closest we have seen to an Unbreakable Balance. Please don't
try this with your Mettler Balance or Ohaus Balance since we think it
might break. The performance depicted in the video can only be
achieved when you choose the Scientech Zeta Series for your next lab
balance. This is the ZETA Series and this demonstration was shown
at Pittcon 2006.
note - the Zeta Series DOES NOT offer the weigh below feature used to
weigh beneath the balance for weighing larger objects. For those

What is so great about this
weighing sensor? Here is the explanation for how the Zeta Series
sensor differs from all other balances on the market today.
Weighing cells use a parallel guidance system in conjunction with some
type of detector, ie. an electromagnetic force restoration (EMFR) detector
or a strain gauge detector. The advantage of the EMFR detectors
is high resolution. The disadvantages are its lever, couplers, and
flexures that can be easily damaged or broken, which results in costly
repairs. The advantage of the strain gauge detectors is that they
are rugged. The disadvantages are its poor resolution.
The Zeta Series bridges the gap between the EMFR detectors and the strain
gauge detectors. Each Zeta model has high resolution since is it
an EMFR detector but also it is very rugged since it does not have a lever,
couplers, or flexures.
The foundation for this new technology is based on a direct-loading weighing
cell concept, which differs dramatically from a normal lever or mono block
sensor design. When used in combination with Scientech's unique
and unequalled displacement detection system and digital servo, the result
is a high quality, weighing sensor offering speed, accuracy and repeatability
you demand for your weighing application.
The Zeta Series is one of the most robust balances on the market and will
not normally suffer suspension damage during shipment like many other
brand balance are exposed to especially with all the rough handling with
the shipping carriers like FedEx and UPS. Unlike other competitor
brands Scientech balances can be repaired. Typical turn around is
within 5-business days. We can't list that other brand name balance
since they will file a lawsuit against us but ask them - can your balance
be repaired if the weigh cell is damaged? You'll be surprised when
they tell you NO and you need to buy a new balance but that is not the
case with Scientech.

ON/OFF button is located in the upper left corner of the balance's
front panel. When the balance is ON the balance automatically
runs a power-up self check.
RANGE/FUNCTION Button: Single Range Balance Models:
Pressing the RANGE/FUNCTION button begins the following menus cycle:
• PCS – Front panel parts counting
• HI OK LO – Checkweighing
• CAL 1 – Auto calibration
• CAL 2 – Linearity
Live animal weighing
• % - percent weighing
To select the desired function, press the MODE switch when it appears
on the display. Note: Front panel parts counting is not available with bi-directional
Dual Range Balance Models:
Pressing the RANGE/FUNCTION button allows you to choose from low (LO),
high (HI) and autorange (HI LO). As a range is selected its annunciator
briefly appears at the upper right of the display. Autorange automatically
switches from low range to high range when a weighing exceeds the capacity
of the low range.
Note: On dual range balance models, pressing the RANGE/FUNCTION
and MODE buttons simultaneously will duplicate the menu shown above
for single range balances.
The ZERO Buttons:
There are two (2) ZERO buttons. Pressing either button at any time
returns the display to zeros. When a weighing that has been zeroed
out is removed from the weighing pan, a negative reading is displayed.
To return the display to zeros, press one of the ZERO buttons.
Pressing the MODE button starts the unit of weight cycle as follows:
grams(g), kilograms(kg), milligrams(mg), pounds(lb), carats(ct), pennyweights(dwt),
troy ounces(ozt), and ounces(oz). When the desired unit of weight
appears, press the MODE button a second time to select that unit of weight.
An optional, factory installed, user specified, custom
unit of measure is available. If you have this special unit
of measure feature in your balance, (A) appears in the unit of weight
cycle after ounces. Press the MODE button to select this function.
Pressing the SEND button sends the information on the balance's
display to an external device via the RS-232 interface.
Note: Scientech balances are DTE (computer) devices. If
communicating to another DTE device (ie computer), a Scientech RS-232
cable, PN11897, or normal null modem cable is required. If you are
communicating to a DCE device (printer), a serial cable is required.
Scientech offers a serial cable for your convenience.
You may send the time and date along with the weight reading
when you press the SEND button or you may send weight readings automatically
at user specified time periods (see the Bi-directional RS-232 Command
Set, Type 4 Commands section for details). Weight readings may also
be sent to a computer or printer continuously every 200 milliseconds (see
the RS-232 Front Panel Configuration section for details). Weight
readings may be sent automatically when the balance reaches stability
(see Selectable Filters section). An optional, factory installed, remote
foot send switch is also available.
Capacity Tracker This
dynamic graphical display automatically depicts the used and unused
portions of your weighing range. The tracker is indispensable
in taring out container weight and then weighing several components
sequentially. You always know how much capacity remains.
Each segment represents 10% of the balance's total capacity.
As 10% of the balance's capacity is used the first segment will
illuminate. As 20% of the balance's capacity is reached the
second segment will light and so on.
Stability Indicator The
balance tells you when the reading is valid, insuring reliable results.
Stability sensitivity is user selectable which allows you to customize
your balance setup. You may disable the indicator at any time.
Check Weighing Here
is Scientech's answer to a go/no-go weight gauge. The balance
tells if your sample weight is too high, too low, or OK. Interpretive
error is eliminated. This application is ideal for JIT environments
where quality of each sample must be assured.
Floating Tare ™(Dual range
models only.) Dual range balances offer you two balances in one. Used
hand-in-hand with autoranging, Floating Tare™ provides low
range readability throughout the entire high range capacity of the
balance. Access Floating Tare™ with the press of a button
and you have ten times more resolution anywhere within the high
can even use a Scientech balance for piece counting. Every
model empowers you to count very small to large components quickly
and accurately. The minimum fixed sample number is ten with
a user selectable larger sample size feature at your fingertips.
Vibration Filters This
feature authorizes you to select a filter setting which is best
suited to your task. If your surroundings are vibration-free,
set the filtering to low which yields results in the fastest possible
time. In more adverse conditions, select either the normal
or high filter parameter. These selections will insure reliable
readings during your different weighing applications.
Units of Measure These multifunctional balances present a choice of eight
different standard units of measure: grams (g), carats (ct), ounces
(oz), troy ounces (ozt), pennyweight (dwt), milligrams (mg), kilograms
(kg), and pounds (lb). Just push the mode button to select
your desired unit of measure. Also available as an option
is a custom weight register which allows any unit of measure you
Live Animal Weighing Weighing
using the time averaging mode is ideal for live animal or severe
environment weighing. This feature also includes a reset function
which allows you to arrive at the final weight reading in seconds
rather than minutes with
Percent Weighing By
quickly selecting the % mode, you are able to weigh a sample in
percent in order to easily determine percent moisture loss, percent
solids, or compounding by percent.
Floating Tare™ (dual range models
Floating tare is only active when the balance is in LO range.
Floating tare yields low range resolution throughout the entire high
range capacity of the balance. A typical example using floating
tare would be where you combine different components by weight to produce
compounds. The procedure is as follows:
Select LO range by pressing the RANGE button until LO briefly appears
in the display.
Place container on weighing pan. If the container weight
exceeds LO range capacity, OL is displayed. If the container
weight does not exceed the LO range capacity, the container weight
Press the ZERO button. The display returns to zeros and LO
Add the first component until the target weight is reached.
Then press ZERO.
Add the second component until the target weight is reached.
Then press ZERO.
Continue until all components have been added.
Floating tare allows you to enter the LO range from anywhere within the
full capacity range of the balance. This feature is particularly
useful when adding small amounts to large tare loads and compounding where
weights are accumulated. Floating tare is only active when the balance
is in LO range. Pressing the ZERO button returns the display to
zeros in LO range. While you are using the floating tare feature,
it is easy to lose track on how much capacity has been used. For
this reason the Capacity Tracking feature is a helpful tool.

In order to determine density of a solid, place a graduated flask with
a known volume of water on the pan of the balance, zero the balance,
and then place the solid in the flask of water. Divide the displayed
weight in grams by the increased volume of water. The result is
the mass per unit volume of the solid in g/cc.
To determine the density of a liquid, place an empty graduated flask
on the balance weighing pan, zero the balance, then pour the liquid
into the graduated flask. Divide the displayed weight in grams
by the volume of the liquid. The result is the mass per unit volume
of the liquid in g/cc.
