5.3. PEAK/VFD (Variable Frequency Drive) Button
In the AC voltage mode, Press the PEAK/VFD key to display “----” first
and then enter the PEAK measurement mode. The maximum PEAK and
minimum PEAK voltage can be measured circularly.
Hold down the button to enter the VFD function measurement. In the
VFD mode, the voltage value of the variable frequency drive device can
be measured. The measured values of “PEAK” and “VFD” are for
reference only.
NOTE: The conductors in electrical cord sets are often twisted. For best
results, rub the probe tip along a length of the cord to assure placing
the tip in close proximity to the live conductor.

4.8. Non-Contact AC Voltage Measurements
WARNING: Risk of Electrocution. Before use, always test the Voltage
Detector on a known live circuit to verify proper operation
1. Touch the probe tip to the live conductor or insert into the live side of
the electrical outlet.
2. If AC voltage is present, the detector light will illuminate.
NOTE: The detector is designed with high sensitivity. Static electricity or
other sources of energy may randomly trip the sensor. This is normal
operation.
To select ACV / Hz / %; OHM / Continuity / Diode / CAP; °C / °F,
ACA/DCA.
5.2.RANGE Button
When the meter is first turned on, it automatically goes into Auto
Ranging. This automatically selects the best range for the
measurements being made and is generally the best mode for most
measurements. For measurement situations requiring that a range be
manually selected, perform the following:
1. Press the RANGE button. The “Auto Range” display indicator will turn
off, The “Manual Range” display indicator will turn on.
2. Press the RANGE button to step through the available ranges until you
select the range you want.
3. Press and hold the RANGE button for 2 seconds to exit the Manual
Ranging mode and return to Auto Ranging.
