7.3.2.1 Direct entry of transducer characteristics
Example: Using 120  individual strain gages, up to 1000 m/will be mea
sured. The gage factor of the strain gage is 2.05. The excitation voltage
plays no role in this example. The setting is described for 2.5 V.
1. Use the channel selection keys
or a direct entry to choose the de
sired channel (for example 3.2
).
2. Use the Switch key
to switch to Setup mode.
3. Press
.
4. In the pull-up menu select Transducer and confirm with
.
5. In the pull‐up menu select Type.
6. Select type in selection field: SG‐1/4 bridge 120 ohms 4‐wr. In the Cur
rent feed selection field choose 2.5 V.
7. Use
to select the Gage factor edit field and enter the value 2.05.
Press the confirmation button
.
Since the amplifier automatically changes the basic unit from mV/V to
m/m after the gage factor is entered, the physical quantity plays no role
in this example. The menu window shown here is based on the display in
the factory settings.
