EJ series compact weighing scales are high-resolution type electronic balances having display resolution of 1/12,000 to 1/60,000. EJ300 balance has a counting function, percentage function and a comparator function. Backlight LCD display will help with weighing in low light places. EJ-300 weigh scale can be operated with an AC adapter, or 4 AA size dry cell batteries for cordless operation. Optional RS232C serial interface can be connected with a printer or personal computer, and Good Laboratory Practice (GLP) data can be obtained. Optional USB interface is available to connect with a personal computer easily.

LCD backlight
The LCD backlight will turn on when the weight value changes more than 4d (4 x min. display division) or any key operation is done. When the weight data becomes and stays stable for some moment, the backlight will automatically turn off. There is also a setting that the backlight is always on or off. For details, see the function setting “ltUp” of “Function list”.

Storage
The EJ series balance can stack on top of another when not in use. Do not stack more than 3 units.

Auto-power off function
It is possible to have the power automatically switched OFF, if zero is displayed for approximately 5 minutes.

Weigh Units
The most common unit of weight used around the world is the gram, but there is often a need to shift to alternative units specific to the country where the balance is used or to select modes such as counting or percent. It is possible to store only the units that will be actually used from the units available. It is also possible to specify the display unit that will be shown first when the power is switched ON.

“Newton” is the value calculated by “(g value) x (9.80665 m/s2) / 1000”.

The range for power-on zero is within ±10% of the weighing capacity around the
calibrated zero point. If the power is switched ON while there is a load beyond this range, the balance will be tared to zero and the NET indicator and the ZERO indicator turn on.
