3-3. Description
○
1
Symbol (-) display
This symbol lamp will be lighted when the output voltage is become less than
0V.
○
2
Voltage display
Output voltage is displayed as in 4 Digit -7 Segment LED.
When output voltage is over 10V or below -10V, it will be displayed as +/-
10.00 and the rest section will be displayed as in +/- 9.000V.
○
3
Zero Hand-operated control volume
It is a volume to control the offset of residual quantity after finishing the auto
zero control.
Control range is within ± 1V.
○
4
Zero auto control switch
Use this switch to carry out auto zero control.
When this auto switch is pressed, “Auto” will appear on the LED and then
zero will be set.
○
6
Bridge voltage selecting switch
This switch is to select the bridge supply voltage.
You can make your selection for the supply voltage among DC 1V, 2V, 5V,
7.5V, 10V.
○
7
Bridge voltage fine control volume
This controls establishing bridge voltage precisely.
○
8
Bridge voltage senscing selecting switch
When select by EXT mode as switch to compensate bridge voltage by
Cable's resistance change, bridge voltage by Cable length change moves
automatically and is corrected.
○
9
Internal CAL Bridge resistance selecting switch
This switch is to select the bridge resistance while you are doing bridge
calibration.
○
10
CAL Strain value switch
It is a shunt switch to calibrate the bridge in two different types - 2000µ and
200µstrain.
○
11
GAIN selecting switch
