SENSITIVITY CALIBRATION
The electronic balance measures mass by electronicity compensating for terrestrial gravitation.
Since gravitation varies slightly in different regions, span calibration (sensitivity calibration) is required
when the balance is installed. Temperature also effects balance accuracy, and calibration must be
performed whenever a significant change occurs. It is good practice to calibrate the balance whenever
the balance is moved or unexpected shock is applied to the balance such that an article drops on the pan.
1. Setting the value of sensitivity calibration weight
In this balance, the value for sensitivity calibration weight can be set freely within the specified range.
Using the weight having known value, sensitivity calibration can be made.
Set the weight value using at sensitivity calibration as follows.
Step

make the display “ ”.
(2) Press the TARE key to set the balance to weight set mode.
(3) The weight value currently set is displayed and the digit to be set
blinks. When the weight value is not changed, press the TARE key.
(4) Pressing the PRINTkey shifts the blinking digit.
(5) Pressing the UNITkey counts up the blinking displayed value.
(6) Repeats the steps (4) and (5) to set the weight value.
(7) When aborting the setting, press the POWER/BRK key. Then
“” is displayed for several seconds, the balance stops
the setting of weight value and returns to weight display.
(8) After the setting of weight value is completed, press the TARE key.
(9) “ ” is displayed for several seconds and the balance returns
to weight display.
