20 IQ plus 2100 Installation Manual
4.0 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.
Figure 4-1. Calibration (CALIBR) Menu
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 (see Figure 4-1). 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
Figure 4-2 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 Figure 4-2 to edit the
value. When done, press
RIGHT to go to the
WSPAN prompt.
NOTE: 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 Figure 4-2 to edit the
value. When done, press
RIGHT to go to the
REZERO prompt.
