Calibration
The IQ plus 210 can be calibrated using the front panel, EDP commands, or the Revolution
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 the RIGHT (UNITS) button until the display reads CALIBR (see
calibration (WZERO).
3. With WZERO displayed, press ENTER to calibrate zero. The indicator displays °CAL° while calibration is in progress.
When complete, the A/D count for the zero calibration is displayed. Press ENTER again to save the zero calibration
value and return to the WZERO prompt or use the procedure shown in
RIGHT to go to the WVAL prompt.
4. With WVAL displayed, press ENTER to show the test weight value. If the value is equal to the test weight you are
using, press ENTER again to save the value and return to the WVAL prompt; if the value is incorrect, use the
procedure shown in
When calibrating the indicator with LB/OZ as the primary unit, enter the WVAL value in ounces. For example, to
Note
calibrate a 5 lb scale using LB/OZ, enter 80 (5 lb x 16 oz/lb) as the WVAL value.
5. With WSPAN displayed, place test weights on the scale then press ENTER to calibrate span. The indicator displays
°CAL° while calibration is in progress. When complete, the A/D count for the span calibration is displayed. Press
ENTER again to save the span calibration value and return to the WSPAN prompt or use the procedure shown in

to edit the value. When done, press RIGHT to go to the REZERO prompt.
