Except for voltage measurements, take no measurements on
electrically “live” systems.
Do not use the instrument if it appears damaged, incomplete, or poorly
closed.
Before each use, check the condition of the insulation on the leads,
housing, and accessories. Any part on which the insulation is
deteriorated (even partially) must be set aside for repair or scrapping.
Using the instrument without its battery compartment cover may result
in electric shock to the user.
Before using your instrument, ensure it is completely dry.
Use only the leads and accessories supplied. The use of leads (or
other accessories) of a lower voltage rating or category limits the use
of the instrument/leads (or accessories) combination to the lowest
category and service voltage.
When handling the leads, test probes, and alligator clips, keep your
Before removing the battery compartment cover, ensure all
measurement leads and accessories are disconnected. Replace all
batteries at once. Use alkaline batteries.
Use personal protection equipment where appropriate.
All troubleshooting and metrological checks must be done by

1.4 Description
The Megohmmeter Model 6536 is a portable measuring instruments with digital
displays, and is powered by batteries. The instrument measures insulation with
test voltages from 10 to 100V in one-volt steps. Other features include:
■Continuity measurement
■Resistance measurement
■ Programmable alarms
The Model 6536 is also available as a oor resistance testing kit (see § 2.2.5)
for testing both point-to-ground and point-to-point electrostatic discharge (ESD).
In addition to the instrument, the kit contains two 5 lb (2.3 kg) oor weights
(also referred to as NFPA probes) that are in compliance with EOS/ESD 11.11
specications. Each oor weight is coated with insulating paint and a conductive
rubber base. The instrument, oor weights, and test leads are packaged in a
rugged eld case. The kit provides all the necessary elements for compliance
with the ANSI/ESD STM97.2-2006 standard for testing ESD ooring.
