Calibration 33
4.0 Calibration
The IQ plus 710 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 five-point linearization
• 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 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 numeric keypad to enter the
actual test weight, then press
ENTER
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
(
WLIN
).
6. Five-point linearization (using the WLIN
parameter) provides increased scale accuracy
by calibrating the indicator at up to five
additional points between the zero and span
calibrations.
