Calibration
The IQ plus 350 can be calibrated using the front panel, EDP commands, or the Revolution
™
Scaleware
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 until the display reads
CALIBR
(see
Figure 4-1). Press to go to zero calibration
(
WZERO
).
3. With
WZERO
displayed, press to calibrate
zero. The indicator displays
*CAL*
while
calibration is in progress. When complete, the
A / D c o u n t f o r t h e z e r o c a l i b r a t i o n i s
displayed. Press again to save the zero
calibration value and go to the next prompt
(
WVAL
).
4. With
WVAL
displayed, place test weights on
the scale and press to show the test weight
value. Use the procedure shown in Figure 4-2
to enter the actual test weight, then press to
save the value and go to span calibration
(
WSPAN
).
5. With
WSPAN
displayed, press to calibrate
span. The indicator displays
*CAL*
while
calibration is in progress. When complete, the
A / D c o u n t f o r t h e s p a n c a l i b r a t i o n i s
displayed. Press again to save the span
calibration value and go to the next prompt
(
REZERO
).
6. The rezero function is used to remove a
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 to return to
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 to rezero the scale. This
f u n c t i o n a d j u s t s t h e z e r o a n d s p a n
calibration values. The indicator displays

calibrations are adjusted. When complete,
the adjusted A/D count for the zero
calibration is displayed. Press to save
the value, then press to return to the
CALIBR menu.
7. Press until the display reads
CONFIG
, then
press to exit setup mode.
