05 OPERATION
Grounding Connection
For proper measurement, the operator should select and wear a wrist strap that is confirmed
functional and properly grounded. Without properly grounded, the accuracy might be affected by the
static charge on the operation making the measurement.
Press the button once to turn the meter ON. The default measuring range is kV/Inch. It is
recommended to let the meter warm up for 10 minutes before making a measurement.
Confirm that the instrument’s display is activated and that the battery low indication (
) is not
displayed. If low battery is displayed, replace the battery.
The two LED ranging lights beside the sensor, also, turn on and the PFM-711B is ready for static
charge measurement.
CAUTION!
The plastic case of the PFM-711B is made of conductive resin. The grounding terminal provides
the reference potential for the electrical circuit. This terminal should be grounded properly for
proper measurement. If it is not properly grounded, the accuracy is not guaranteed.
Static Charge Measurement
1.
With the operator’s fingers contacting the grounding snap on the back of the meter (Figure 3),
press the green RANGE button switch to select the kV/inch range. The LED for kV/inch will be
illuminated.
2.
Hold a flat sheet of material in front of the meter’s sensing plate to confirm operation of the
ranging light system. A circle with a spot in the middle should appear clearly on the material
surface when held 1” (25mm) from the meter’s sensing plate (Table 3).
3.
Point the unit away from surfaces and objects. Press and hold the yellow ZERO button until
the display indicates 0.00.
4.
The PFM-711B Field Meter is now ready for static charge measurements.
5.
To turn off the meter, press and hold the
button for 2 seconds.
