CAUTION!
Do not exert excessive pressure; it might damage the battery compartment cover.
Be careful while connecting or disconnecting a battery. Do not pull the plug by the
connecting leads.
The plug will be damaged when it is connected forcibly in the wrong polarity terminals.
Before closing the cover, make sure that no part of the leads are outside the battery
compartment.
04 FUNCTION
Zero Adjustment
A blue ZERO button switch on the front panel can be used to adjust the reading to zero (0.00) if the
field meter reading is not zero. To make PFM-711B read zero in this condition, press and hold the
ZERO button pointing the unit away from charged surfaces and objects. You may need to press and
hold the zero button more than once to obtain zero (0.00).
Note: When the PFM-711B is in HOLD mode, the Zero Adjustment function is inoperative.
Range Selection
The green RANGE button switch allows the user to select the proper range of measurement. When
turning the meter on, the default range selected is kV/inch. By pressing the RANGE button, the range
is switched to V/inch.
Note: If turning the meter off while in the V/inch range, the meter will default back to kV/inch when
turning the meter back on.
Hold Function
With the meter in the measurement position, press the HOLD. This will freeze the digital
measurement on the display, allowing the meter to be moved to a position where it may be more
easily read and documented.
When the meter is in the HOLD function, the LED of the selected range will be blinking. The two LED
ranging lights are turned off. We recommend putting the meter in the HOLD function between
measurements to preserve battery life.
