Executing Balancing
Balancing automatically compensates the unbalanced portion of the bridge resistance.
The execution of balancing takes a few seconds.
Executable range of balancing:
±
10000
µ
STR (when set to
µ
STR)
±
5 mV/V (when set to mV/V)
Inverting the Waveforms
See section 5.12.
Precautions to Be Taken When Making Strain Measurements
• Be sure to execute balancing when measuring the strain.
• Select a bridge voltage of 5 V or 10 V when the bridge resistance is greater than or
equal to 350
Ω
. If a bridge voltage of 5 V or 10 V is applied when the bridge
resistance is less than 350
Ω
, correct measurements will not be made.
• If using a strain gauge transducer, use a bridge voltage in the recommended voltage
range of the transducer.
• Correction cannot be executed if a strain gauge bridge (bridge head) or a strain gauge
transducer is not connected to the channel on which balancing is to be executed.
• If balancing fails on any of the specified channels, an error message and information
on the failed channel is displayed.
• If the power is turned ON, a new strain gauge is connected, or the measurement
range, bridge voltage, or gauge factor is changed, balancing must be performed again
before making measurements.
The scale value indicates “imbalance” immediately after power-up or when the range
is changed. If this indication is showing, execute balancing.
• If you switch the unit, the unit of all related parameters of the channel is switched
accordingly (upper and lower limits, trigger level, measured values of automated
measurement parameters, cursor measurement values, etc.).
