7. 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.
7.1 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.
