CHAPTER 1
INTRODUCTION
Warning
These safety warnings are provided to ensure the safety of
personnel and proper operation of the instrument.
• Read the instruction manual completely and follow all safety
information before operating this instrument.
• Safety is the responsibility of the operator!
• Tests are to be carried out only on non-energized
circuits! Check for live circuits before making resistance
measurements (safety check).
• The Megohmmeter Models 1035 and 1039 are sources
of high voltage, as is the sample connected to them. All
persons performing or assisting in the tests must employ all
safety precautions to prevent electrical shock to themselves
and to others.
• Use personal protective equipment where appropriate.
• When testing capacitance samples, make sure that they
have been properly discharged and that they are safe
to touch. Dielectric insulation samples should be short-
circuited for at least ve times the amount of time they were
energized.
• Megohmmeters should never be used in an explosive
environment.
• Use the leads supplied with the megohmmeters. If they are
defective or worn, replace before testing.
• NEVER use the megohmmeters on electrical conductors
rated above 600 V in overvoltage category III (CAT III).

1.1 International Electrical Symbols
This symbol signies that the instrument is protected by
double or reinforced insulation.
This symbol on the instrument indicates a WARNING and that
the operator must refer to the user manual for instructions
before operating the instrument. In this manual, the symbol
preceding instructions indicates that if the instructions are not
followed, bodily injury, installation/sample and product damage
may result.
Risk of electric shock. The voltage at the parts marked with this
symbol may be dangerous.
In conformity with WEEE 2002/96/EC
1.2 Denition of Measurement Categories (CAT)
CAT IV corresponds to measurements performed at the primary electrical
supply (< 1000 V).
Example: primary overcurrent protection devices, ripple control units, and
meters.
CAT III corresponds to measurements performed in the building installation
at the distribution level.
Example: hardwired equipment in xed installation and circuit breakers.
CAT II corresponds to measurements performed on circuits directly
connected to the electrical distribution system.
Example: measurements on household appliances and portable tools.
1.3 Receiving Your Shipment
Upon receiving your shipment, make sure that the contents are
consistent with the packing list. Notify your distributor of any missing
items. If the equipment appears to be damaged, le a claim immediately
with the carrier and notify your distributor at once, giving a detailed
description of any damage. Save the damaged packing container to
substantiate your claim. Do not use an instrument that appears to be
damaged.

CHAPTER 2
PRODUCT FEATURES
2.1 Description
These portable megohmmeters function with batteries. They can be used
to check insulation and voltages, and to measure resistances. The
Model 1039 can also be used for:
• measurement of the capacitance of a telephone line
• current measurement
• measurement of the pure alternating component of a DC
voltage
These megohmmeters help to ensure the safety of electrical and
telephone installations. The acquisition, processing and display of the
measurements are managed by a microprocessor. They o󰀨er a wide
range of advantages such as:
• automatic detection of the presence of a dangerous voltage
on the terminals in MΩ ranges (all insulation measurement
blocked if V > 25 V)
• protection of the instrument against external voltage surges
• operator safety by means of automatic discharge of the high
voltage on the equipment tested
• display of the di󰀨erence compared to a measurement value
in memory
• measurement of the length of a telephone line according to
its capacitance per km unit length (1039)
• automatic shutdown of the instrument to save the batteries
and indication of the battery charge
• fuse testing by periodic checks during current measurement
(1039)
• a large backlit LCD screen with a wide range of indicators
making it very easy for the user to read
