I. Introduc on
The PFM-711A is an accurate, compact electrosta c fi eldmeter used for loca ng and measuring sta c
charge poten als. Other types of electrosta c measurements may also be made using the PFM-711A and
its accessories.
A. The PFM-711A features SAMPLE and HOLD measurement modes that allow measurements to be
made in places that would be diffi cult to reach or see with other instruments.
B. Range switching is provided with the PFM-711A. In V/inch mode, the digital display covers the
range of 0 ±1999 volts in one volt increments. In kV/inch mode, it covers the range of 10 volts to
20kV in ten volt increments.
1. An analog output jack provides a 1 volt output corresponding to 10kV, which is independent of
the range selected and meter indica on.
2. The circuitry is a digital, electronic chopper design and subsequently, the instrument is useful
for making electrosta c fi eld measurements in areas where ionized air is present.
3. For accurate, repeatable performance, the PFM-711A must be grounded during normal
opera ons.
II. Cau ons & Warnings
A. Do not point the PFM-711A Field Meter Ranging Lights into anyone’s eyes.
CAUTION
Do not point ranging lights into anyone’s eyes.
B. Do not store or use instruments in damp environments.
C. The PFM-711A Field Meter case must be grounded for proper opera on.
CAUTION

D. Turn OFF all instruments when in storage or transit. Remove ba eries when instruments are in-
tended for long-term storage, i.e. six months or longer.
