1.1 International Electrical Symbols
This symbol signifies that the instrument is protected by double or rein-
forced 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 Definition of Measurement Categories
CAT I: Formeasurementsoncircuits not directlyconnectedtotheAC
supply wall outlet such as protected secondaries, signal level,
andlimitedenergycircuits.
CAT II: For measurements performed on circuits directly connected to
the electrical distribution system. Examples are measurements
onhouseholdappliancesorportabletools.
CAT III: For measurements performed in the building installation at
the distribution level such as on hardwired equipment in xed
installationandcircuitbreakers.
CAT IV: For measurements performed at the primary electrical supply
(<1000V) such as on primary overcurrent protection devices,
ripplecontrolunits,ormeters.

2.1 Description
The Megohmmeters Model 1030, 1040 and 1045 are battery powered
digital insulation resistance testers. They are designed to measure
insulationresistance,continuity,voltage,andtomeasureresistance.
These megohmmeters are used to verify the safety state of electrical
installations,motors,cablesandotherinsulatedproducts.Themeasure-
mentacquisition,processinganddisplayingtechnologyaremanagedby
amicroprocessor.
The Models 1030, 1040 and 1045 offer many features such as:
