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 

 

(1) Following the menu selection, press the 

CAL/MENU

 key to 

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 

PRINT

 key shifts the blinking digit. 

(5) Pressing the 

UNIT

 key 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. 

(10) When setting the weight value exceeding the specified range, 

” is displayed and then the balance returns to weight   

display.
