Tester

Key features

• Small, lightweight, self-con-

tained portable instrument

• Universal power supply—

input voltage from 85 V ac to

265 V ac

• Chassis resistance mea-

surements are made with a

four-wire Kelvin bridge to

eliminate errors due to cable

length

• Test method complies with

AAMI load per ANSI/AAMI

ES1-1993

• Leakage current can be mea-

sured in Open/Closed Neutral,

Normal/Reversed Polarity and

Open/Closed Ground

• All Leakage current measure-

ments are displayed directly

in µA

This device is designed

to perform simple

electrical safety tests

on any type of medical

equipment, whenever

patient lead testing is

not required.

The rugged, hand-

held instrument is built

for quick and easy use.

A simple selector knob

controls the functions:

Leakage Current and

Chassis Resistance.

Accurate test measurements are shown on the large display.

Heavy-duty switches change polarity, open and close the neutral and

select Chassis or Earth Leakage Current measurements. A four-wire Kelvin

bridge eliminates reading errors in resistance due to cable length and

contact resistance. True-rms measurements are provided for all current

readings. The AAMI test load is utilized.
