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.
