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)
