2.1.5 BAsIC sETTING PROCEDURE TO sET sCALING VALUEs WITH ACTUAL LOAD
The following shows the procedure to set the input to 0 – 10 mV DC and the display to 0.0 – 300.0 kg using a strain gauge
with the rated output 2 mV/V, recommended excitation voltage 5 V, and a weight 30 kg, 10% of the rated load 300 kg as an
example. Set values meeting signals of equipment to use. Refer to 4. SETTING EXCITATION VOLTAGE for details of set-
ting. Adjust tare as necessary. Refer to 7. ADJUSTING TARE for details.

BAsIC sETTING PROCEDURE
The basic setting procedure is as follows.
1
Confirm the wiring, turn on the power and move on to Scaling Setting Mode (measurement stopped).
•
Warm up the unit for 10 minutes or more.
•
Hold down Scale/
↑
button for 3 seconds or more.
2
Set excitation voltage.
•
Press Alarm/
↓
or Scale/
↑
button to go to the next or previous parameter setting.
•
Press Shift button to shift the display into the setting standby mode and Up button to select the excitation voltage.
3
Set input scaling value A.
•
Press Alarm/
↓
or Scale/
↑
button to apply the new setting and go to the next or previous parameter setting.
•
Press Up button to go to the teach calibration (ZERO) setting.
•
Without any load (equivalent to input 0%), press Up button to register the present value.
4
Set display scaling value A.
•
Press Alarm/
↓
or Scale/
↑
button to go to the next or previous parameter setting.
•
Press Shift button to shift the display into the setting standby mode.
•
Press Shift button to go to the next digit and Up button to change the blinking value.
5
Set load ratio.
•
Press Alarm/
↓
or Scale/
↑
button to apply the new setting and go to the next or previous parameter setting.
•
Press Shift button to shift the display into the setting standby mode.
•
Press Shift button to go to the next digit and Up button to change the blinking value.
6
Set input scaling value B.
•
Press Alarm/
↓
or Scale/
↑
button to apply the new setting and go to the next or previous parameter setting.
•
Press Up button to go to the teach calibration (SPAN) setting.
•
With 30 kg load (equivalent to input 100% × load ratio 10%), press Up button to register the present value.
