Calibration
The
IQ plus 210
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.

4.1 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
). Press
ENTER
(
ZERO
) to go to zero
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
to edit the value. When done, press
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
to edit the value. When done, press
RIGHT
to go to the
WSPAN
prompt.
When calibrating the indicator with LB/OZ as the primary unit, enter the WVAL value in ounces. For example, to
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.
