Calibration

The IQ plus 710 can be calibrated using the front panel, EDP commands, or the Revolution
utility. Each method consists of the following steps:
• Zero calibration
• Entering the test weight value
• Span calibration
• Optional five-point linearization
• Optional rezero calibration for test weights using hooks or chains.
The following sections describe the calibration procedure for each of the calibration methods.

Front Panel Calibration

To calibrate the indicator using the front panel, do the
following:
1. Place the indicator in setup mode (display
reads ) and remove all weight from the
CONFIG
scale platform. If your test weights require
hooks or chains, place the hooks or chains on
the scale for zero calibration.
2. Press until the display reads

parameter) provides increased scale accuracy
by calibrating the indicator at up to five
additional points between the zero and span
calibrations.
