Calibration Mode Exit Conditions
Calibration Mode exits under the following conditions:
•
No response is received from an external operator for 30 seconds (Firmware Version 3.4 or later) or 90
seconds (Firmware Version pre-3.4). This timeout does not apply at
Step 5 - Calibration Success or
Failure .
•
The operator turns the MP6000 off.
•
Step 4 - Calibration at LOAD completes successfully, or unsuccessfully (fails).
•
A user scans Scale Reset (refer to the MP6000 Bar Code Programming Guide , p/n 72E-172633-xx).
When Scale Reset is scanned, a test runs, showing a series of characters on the optional Scale Display.
When the test completes, the scale returns to its prior state before entering a scale Calibration Mode.
See
Table 4-6 on page 4-21 ( Cold reset of scale ) for the character sequence displayed.
Verification Test
Table 4-3 describes the five tests needed to verify whether or not the scale was calibrated successfully.
The verification tests outlined in Table 4-4 and Table 4-5 can be run in successive order. Use the appropriate
table based on US (lb), or metric scales (kg), using applicable tolerance for single or dual interval scale
models.
Table 4-3
Tests to Verify Scale Accuracy
Test Description
Increasing Load Test This test verifies accurate weight measurement with increasing weights placed
incrementally on the scale's platter, without returning weight to zero.
Over Capacity Test This test verifies that the correct indication appears on the Scale Display when
the maximum weight is exceeded.
Decreasing Load Test This test verifies accurate weight measurement with decreasing weights removed
incrementally from the scale's platter, without returning weight to zero.
Return to Zero Test This test verifies that the scale returns to zero when all weights are removed.
Shift Test This test verifies accurate weight measurement in all quadrants.
