Peak Hold Measurements
Note: The peak hold feature calibrates itself to meet the
specifications.
The function of the peak hold feature is to record and
store the positive and negative peak values that occur
while measuring ac current or ac voltage. To enable the
peak hold feature press the PEAK ± button for more
than 2 seconds. The display will show CAL to indicate the
calibration cycle is in process. After the CAL indication
clears, press the PEAK ± button again to display the
maximum (P+) value for the ac voltage or ac current
being measured. The display will toggle between the P+
and P- readings each time the PEAK ± button is pressed.
Press the PEAK ± button for more than 1 second to exit
the PEAK function.

the following procedure:
1. Set the Function Switch to OFF.
2. Press and hold the HOLD button while turning the
Function Switch to the desired function. The no-beep
