Perform this step under the following conditions:
• Turn on the instrument and wait 30 minutes.
• Connect a strain gage or strain gage-type converter to the module; however, do not apply any
loads, including vibration.
• Connect the B and D inputs terminals with one another when measuring voltage.
Auto-balancing cannot be performed while measurement is in progress.
Key operations are ignored while auto-balancing is in progress.
Perform auto-balancing again in the following circumstances:
• When the input types have changed
• When the range has changed
• When module connections have changed
• When the strain gage or strain gage-type converter has changed
• When the instrument's power has been cycled
• When the instrument's settings have been initialized
• When the ambient temperature has changed abruptly (when the zero position may have drifted)
If auto-balancing fails, check the following:
• Is the strain gage or strain gage-type converter in a no-load state?
• Is the strain gage or strain gage-type converter connected properly?
