Calibration

The IQ plus 350 can be calibrated using the front panel, EDP commands, or the Revolution
configuration utility. Each method consists of the following steps:
• Zero calibration
• Entering the test weight value
• Span calibration
• 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 CONFIG ) and remove all weight from
the 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

calibration offset when hooks or chains are
used to hang the test weights.
• If no other apparatus was used to hang the
test weights during calibration, remove
the test weights and press
the CALIBR menu.
• If hooks or chains were used during
calibration, remove these and the test
weights from the scale. With all weight
removed, press
