Programming Note Save (SAVE?)
After entering the last display value, the scaling entries must be saved (SAVE?) before they will be put
into effect. However, you may move past this selection using the Up arrow key if you need to go back
and correct an earlier entry. Once confident in the entries, however, the user must navigate back to
the Save menu screen (SAVE?) and press the Enter key to save the changes.
Error messages (Error)
An error message indicates that the calibration or scaling process was not successful. After
the error message is displayed, the meter reverts to input 2 during calibration or scaling,
allowing the appropriate input signal to be applied or programmed.
Conditions causing an error message:
1. Input signal is not connected to the proper terminals or it is connected backwards.
2. Minimum input span requirements are not maintained.
3. Input 1 signal inadvertently applied to calibrate input 2.
Minimum input span
The minimum allowed input span is 1 Hz. This is the minimum difference between input 1
and input 2 signals required to complete the calibration or scaling of the meter.
Important
After entering the last display value, save (SAVE?) the calibration entries. You may move past this
selection using the Up arrow key if you need to go back and correct an earlier entry. Then save the
changes on the Save menu screen (SAVE?) by pressing the Enter key.
