Digital Static Locator
Installation, Operation, and Maintenance
Description
Desco’s Digital Static Locator is a compact
electrostatic fieldmeter used for locating and measuring
static charges.
The Digital Static Locator measures static voltages
within ±20kV (20,000V) at a distance of 1". Results
are simultaneously displayed numerically and in bar
graph format. POWER on/off, ZERO adjustment, Ion
Balance (IB) and HOLD are all push button operation.
The HOLD button allows the display to retain the static
charge reading. This is especially useful where display
is difficult to see during measurement.
Two LED guide ring range lights help position the
fieldmeter at the right distance from a charged surface.
The conductive case and ground snap facilitate
grounding for accurate measurement. The circuitry of
the 19430
has been designed to make measurements
in areas using air ionization.
Packaging
1 Digital Static Locator
1 Plate Assembly
1 Ground Cord
1 Battery
Features
The 19430
has four push buttons. The buttons operate
by pressing once lightly. There is no need to press the
button repeatedly. Its effective life may be decreased by
repeated misuse.

The POWER button turns the Digital Static Locator on
and off. If the 19430
is left on for 5 minutes, it will
automatically turn itself off. To resume operations, press
the red POWER button once. To disable the AutoOff
feature and allow continuous operation, press the red
Power button and hold down for at least 3 seconds
when turning the Digital Static Locator on.
The HOLD button holds the display of a measured
charge. HOLD mode turns off the ring range lights. No
measurements are possible when in the HOLD mode.
The hold measurement feature enables the user to use
the fieldmeter in inaccessible areas. When the HOLD
button is pressed once during a measurement, the
digital numerical value and the bar graph will be held on
the display. This function allows the operator to move
the fieldmeter where it can be more easily read. The
HOLD mode is displayed above the battery capacity
display. To cancel HOLD mode and resume
measurement, press HOLD once more.
The IB button and prepares the fieldmeter for Ion
Balance (offset voltage) measurement.
The ZERO button sets the display to a zero static
charge. When the digital meter is turned on, the zero
adjustment is inoperative if it is in HOLD mode.
NOTE:
For reliable measurement, the fieldmeter must
be grounded properly using the ground lead provided.
The plastic case of the 19430
Electrostatic Fieldmeter
is made of conductive resin. The grounding terminal
provides the reference potential for the electrical circuit.
This terminal must be grounded properly for accurate
measurement.
Operation For Static Charge Measurement
1. Turn the ring range lights and sensor toward a
surface to be evaluated.
2. Press the POWER button. A single beep for one
second indicates proper operation. The battery
capacity indicator and bar graph will be displayed.
3. The meter reading should be zero (0). Use the ZERO
button if it is not.
