Calibration
The 482-AG can be calibrated using the front panel. This chapter describes the calibration procedure for each of the calibration
methods.
• Zero calibration
• Entering the test weight value
• Span calibration
• Optional rezero calibration for test weights using hooks or chains
4.1 Front Panel Calibration
The
CALIBR
sub-menu is used to calibrate the 482-AG, see
for the calibration menu structure and
parameter descriptions. Use the following steps to calibrate the indicator using the front panel.
1. Remove the configuration switch access screw from the back of the enclosure, see
.
2. Insert a non-conductive tool into the access hole and press the configuration switch.
CONFIG
is displayed.
3. Press until
CALIBR
is displayed.
4. Remove all weight from the scale platform. If the test weights require hooks or chains, place the hooks or chains on
the scale for the zero calibration.
5. Press to
WZERO
.
6. Press to
CAL
.
7. Press to
ENTER
.
8. Press to calibrate zero. The indicator displays
*CAL*
while calibration is in progress. When complete, the mV value
for the zero calibration is displayed.
9. Press to save the zero calibration.
CAL
is displayed.
10. Press to
WZERO
.
11. Press to
WVAL
.
12. Press to show the test weight value.
13. Press to edit value using the procedure shown in
to enter the actual value of the test weights
to be used for the span calibration. Press to store the entered
WVAL
value.
14. Press to
WVAL
.
15. Press to
WSPAN
.
16. Press to
CAL
.
17. Press to
ENTER
.
18. Place test weights on the scale and press to calibrate span. The indicator displays
*CAL*
while calibration is in
progress. When complete, the net millivolt value of the test weight for the span calibration is displayed.
Net mV value is equal to the raw mV value at the span minus the mV value captured for zero.
19. Press to save the value.
CAL
is displayed.
20. Press to
WSPAN
. If using chains or hooks for the test weights, proceed with
If no chains or hooks were used, proceed with
.
21. Press to
REZERO
. The
REZERO
function is used to remove a calibration offset when hooks or chains are used to
hang the test weights.
22. Remove the hooks or chains used during calibration and remove the test weights from the scale.
23. Press .
ZERO
will flash. With all weight removed, press to rezero the scale. This adjusts the zero and span
calibration values. The indicator displays
*CAL*
while the zero and span calibrations are adjusted.
24. Press to return to the CALIBR menu.
25. Press until the display reads
CONFIG
.
26. Press to exit configuration mode.
Saving
is displayed and the scale returns to the weigh mode.
The INIZR (initial zero) parameter may affect the weight display reading immediately following calibration.
