Pressing the HOLD button again will cancel the HOLD function and return the meter in its measuring
position.
Note: The display of measured voltage is not saved in PFM-711B, even if it is turned off in HOLD
mode. Data and mode information will be lost by turning the meter off.
LED Ranging Lights
The PFM-711B has two red LEDs on the front end of the meter to position the unit at the right
distance from a charged object.
Hold the front of the meter approximately 1” inch (25mm) from the surface to be measured. Adjust
the distance from the test surface until the ranging lights form a Bull’s Eye (Table 1). Allow the
instrument to stabilize.

WARNING!
Do not shine the RED Bull’s Eye Ranging lights into yours or anyone else’s eyes.
Analog Output Mode
With the optional analog output cable, you can use an analog out. The analog output cable is used to
connect the PFM-711B Field Meter to an X-Y Plotter or analog data recorder or timing device.
The analog output is a 2.5 mm jack (3/32”) monophone jack
may be connected to an oscilloscope,
strip chart recorder, external meter or other device. 1 volt at this output corresponds to 10 kV
±20
kV.
