1 Digital Static Field Meter
1 9V Alkaline Battery
1 Data Output Cord
1 Certificate of Calibration
Features and Components
C. Analog Output Jack:
A low-voltage replica of the
measured voltage is provided at this output. The voltage
at this output is 1/1000th (±2 kV range) or 1/10,000 (±20
kV range) of the measured voltage.
D. POWER Button:
Press to turn the unit ON and OFF.
E. 4mm Stud:
Use this stud to ground the Meter using
a 4mm ground cord (not provided - any standard single
wire wrist strap cord can be used).
F. Battery Cover:
Slide the cover down to open the 9V
battery compartment.
Operation
Note:
The
19492
Digital Static Field Meter is built in a
conductive case. The instrument senses the difference
in potential between the case (and the person holding
the case / ground connection) and the surface under
test. Ensure that the person using the instrument is
grounded or that the rear panel ground snap connection
is utilized to achieve accurate measurements.
BATTERY CHECK
The battery should be replaced when “BAT” is indicated
on the display. Always replace the battery with a 9V
alkaline or equivalent battery in order to remain CE
compliant.
ZERO THE METER
Turn the meter on by pressing the POWER button.
Press the RANGE / ZERO button to set the meter to
the 2 kV (3 decimal places) range. Point the top of the
Meter approximately 1 inch away from a grounded metal
surface. Use the red LED range guide. The Meter is
properly positioned when the projected red bullseyes
are centered on top of each other. Press and hold the
RANGE / ZERO button until the meter displays “.000”.
MAKING A MEASUREMENT
Place the meter 1 inch from the object to be measured.
This distance is measured from the front edge of the
meter case to the surface of the object. The meter now
displays a reading (from 0 to ±.200 or ±2.00) of the
electrostatic field in kilovolts per inch.
Note:
The red ranging lights are provided to help place
the meter at the correct distance from the object. The
lights are set to produce a concentric red bullseye
pattern on a flat opaque surface 1 inch from the front
edge of the meter. This can be practiced by aiming the
meter at a sheet of white paper.
The display will indicate “1” or “-1” when the meter is
over-ranged. Change the range of the unit if necessary.
If the measurement exceeds 20 kV, move the meter
farther away from the object and multiply the reading
by the distance (in inches) away from the object being
measured. The measurement accuracy is dependent on
