3.2 Changing the Range
______________________________________________________________________________________________
3.2.1 Strain Gauge Input
F1 F2 F3
3.2 Changing the Range
Channel A (Strain Gauge) can be used for the torque meter output, and has
three ranges: 1 mV/V, 1.5 mV/V, and 2 mV/V. The full scale screen display
values for these ranges are 1.0000, 1.5000, and 2.0000 respectively (when
the scaling value is 1). The scaling value is calculated as follows:
Scaling value = (rated torque value for the combined torque meter) / (full
scale value for the range) After selecting the range, set the units to finish
setting channel A.
When a rated torque of 100 N.m and a rated
output of 1.5 mV/V torque sensor are combined:
1. Set the channel A "VOLTAGE RANGE" to 1.5
mV/V.
2. Set the channel A "SCALING" to 66.667.
3. Set the channel A "UNIT" to N.m.

Both channels A and B have three ranges, of ±1V,±5V,and±10 V.
Changing on the MEAS screen
The range for channel A corresponds to the voltage
range switching key, and the range for channel B
corresponds to the current range switching key.
Changing on the STATUS screen
1. Display the "EXT UNIT" page on the STATUS
screen.
2. With the CURSOR keys, move the cursor to the
"VOLTAGE RANGE" to be changed.
3. Select the voltage range with function keys
F1 (1V

3.5 Zero adjustment
______________________________________________________________________________________________
NOTE ･If the value does not become "0" even if you perform zero adjustment, try moving
the position of the cable.
･The zero point may differ depending on the rotation frequency, even if no torque
is applied to the torque sensor. Perform zero adjustment after you have set the
required rotation speed.
･After zero adjustment, do not move the cable. This could disturb the
zero point.
