4. Press the
ISO TEST
switch to safely apply the high voltage to the leads.
5. While the
ISO TEST
is energized, read the isolation current in µA.
6. Take measurements for all combinations of the
OUTLET
in
both
NORMAL
and
REVERSE

External Measurements
The Analyzer provides the extended capability of making leakage current and
isolation current measurements between selected points, performing as
follows:
•
An ohmmeter capable of measuring resistance in the m
Ω
range for chassis
bonding measurements.
•
A low impedance (1000
Ω
) voltmeter as specified by the NFPA, with a
range to 1999 mV.
•
A 1000 µA ammeter to measure the leakage current between two devices
or between the DUT and a local ground reference. Range is to 1999 µA.
•
An isolation tester for testing ultrasound probes and other transducers
independently from the device in which it is used.
Note
Additional optional accessory cables must be purchased to perform
these tests.
