so forth).
Note
After pressing g, wait until the step number advances before changing the calibrator
source or turning the Meter’s rotary knob. Some adjustment steps can take up to several
seconds to execute before moving to the next step.
If the knob is not in the correct position for a given step, the meter will flash the unit
annunciators until the knob is put in a valid position. The keys that show the reading and
required input values are not allowed until the knob is correct.
Likewise, if the rotary switch is not in the correct position or the measured value is not within
the anticipated range of the input value, the Meter will emit a double beep and will not
continue to the next step when gis pressed.
8. After the final step, the display shows “End” to indicate that the calibration adjustment is complete.
Press gto return to meter mode.
Note
Set the calibrator to Standby prior to changing the function switch position and after
completing adjustment of each function.
