2-2. How to Set Calibration Value (CAL)
The indicated value is calculated value based on input. The value can be set from 1
με
to. 9999
με
by a step of 1
με
(=10-6). Values should be set for each digit (Figure 2-3).
Pressing calibration value setting knob (12) (Figure 2-4) illuminates the fourth digit of calibration
value LED (13). Turning the switch changes the value on (13). Even the indication is blinking, the
setting is being made.
Press the knob when your target value is indicated. In this case, blinking of (13) turns to
illuminating (value fixed), and then the third digit starts blinking. Repeat this step up to the first
digit. After the first digit comes on and then all digits illuminates, calibration value setting
completes. To change the calibration value, repeat the steps above. The value is based on the
equivalent value for gage factor 2.00 and one gage configuration. For strain gage type transducer,
set and calculate the value based on 1 mV/V = 2 000
