HOLDING THE LAST READING
Press the HOLD button to freeze the reading from the
object on the display and the analog output signal. This
feature allows the operator to move the Meter where it
may be more easily read or saved for later reference.
made at the location where ESD sensitive items are
to be ionized. Air ionizer heaters and air filters (if so
equipped) should be left in their normal conditions during
test.”
ANALOG OUTPUT
The analog output jack labeled “OUT” on the face of
the Meter accepts a standard 2.5 mm monaural phone
plug and is provided so the output of the Digital Static
Field Meter may be connected to an oscilloscope, strip
chart recorder, external meter or other device. Use the
included cord to achieve a connection between the Field
Meter and alternate measuring instrument. The voltage
at this output is 1/1000th (±2 kV range) or 1/10,000 (±20
kV range) of the measured voltage.
TAKING DISCHARGE TIME MEASUREMENTS
In order to verify that an ionizer is operating properly it is
also important that its ability to neutralize or discharge
static electricity is measured. The following procedure
will measure an ionizer’s discharge time:
OPERATING THE CHARGER
The Charger has a momentary rocker-switch that powers
the unit. Holding the switch forward / backward supplies
power to the output terminals.
POLARITY SELECTION
The top of the rocker switch is labeled “+”, and the
bottom is labeled “-”. To provide a POSITIVE voltage
output, touch the plate located underneath the charger,
and press the switch forward at the same time. To
provide a NEGATIVE voltage output, touch the plate
located underneath the charger, and press the switch
downward at the same time.
Note: For the Charger to work correctly, the operator
and Field Meter must be properly grounded. A ground
path to the touch plate must exist.
IONIZER DISCHARGE TIME MEASUREMENTS
Use the Field Meter with the conductive plate in the
appropriate location for measurements.
POSITIVE DISCHARGE TIME MEASUREMENTS
To provide a POSITIVE voltage output, touch the plate
located underneath the Charger, and press the switch
forward at the same time. Momentarily touch the
Charger’s output terminal to the conductive plate
attached to the Field Meter. The meter reads
approximately +1.10 kV. By using a stop watch or other
timing device, determine the time needed for the
voltages to decrease from +1.10 kV to +0.10 kV. This is
the positive discharge time.
