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. Its pocket size makes it handy to use
and four button operation makes it easy to operate.
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 lights help position the fieldmeter at
the right distance from a charged test object. 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.
Features
• Easy to read, easy to use operations
• Lightweight, compact design
• Range light assures accurate and repeatable
measurements
• Automatic range switching up to ±20kV (20,000V) at 1"
(25mm)
• Digital and bar graph display
• Automatic power off after five minutes (may be
disabled if preferred)
