Executing balancing : Balance
The unbalanced portion of the bridge resistance is automatically corrected. The balancing takes
a few seconds.
Balance range :
± 10000uSTR
Precautions when making strain measurements
• If there is no strain gauge bridge (bridge head) or strain gauge transducer connected to the
channel you wish to balance, calibration fails.
• Select a bridge voltage of 5 V when the bridge resistance is 350 Ω or more. Applying a
bridge voltage of 5 V when the bridge resistance is less than 350 Ω results in incorrect
measurements.
• When using the strain gauge transducer, make sure to set the bridge voltage within the
recommended voltage range of the transducer.-
• If any one of the specified channels fails to balance, then an error message and information
about the channel that failed are displayed.
• If the power is turned ON, a new strain gauge is connected, or the bridge voltage or the gauge
factor is changed, you need to balance again.
Operating Procudure
1. Press one of the keys (channel key that has the strain module installed),
CH1
to
CH16
, to
select the channel.
Select the measurement range
2.
Press the “ Range ” soft key and select one from “ 20000uSTR ” to “ 1000uSTR .”
Set the display range
3.
Press the “ Upper Scale/Lower Scale ” soft key and set the jog shuttle action to “ Upper
Scale .”
4. Turn the jog shuttle to set the upper limit.
You can change the setting a digit using the arrow keys.
5. Similarly, set the lower limit with “ Lower Scale .”
Select the bridge voltage
6.
Press the “ Excitation/Gauge Factor ” soft key to select “ 2V ” or “ 5V .”
Set the gauge factor
7.
Continuing from step 6, turn the jog shuttle to set the gauge factor.
