1.1 PRECAUTIONS FOR USE
These safety warnings are provided to ensure the safety of personnel and proper
operation of the instrument.
■Do not attempt to perform any tests with these instruments until you have read
the instruction manual.
■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).
■High voltage is present, as is the sample connected to it. Anyone performing
or assisting in testing must follow all safety precautions to prevent electrical
shock to themselves and others.
■Use personal protective equipment where appropriate.
■When testing samples with a capacitive component, make sure they have
been properly discharged and are safe to touch. Dielectric insulation samples

energized.
■Do not use the megohmmeter in areas where explosive or ignitable substances
are present. The testing of electrical systems with a megohmmeter could create a
spark and cause a hazardous situation.
■Only use the leads that are supplied with the megohmmeter. If they are
defective or worn, replace before testing.
■This instrument can be used on installations rated for 1000 V, Category III.
1.2 RECEIVING YOUR SHIPMENT
■Match the contents with the ordering information.
■Notify your distributor of any missing items.

■Automatic detection and measurement of voltage/frequency/input current.
■Quantitative and qualitative insulation measurement.
• Measurement at 500/1000/2500/5000 V or other test voltage between
40 and 5100 V (adjustable voltage).
• Measurement in voltage step mode (the applied voltage increases in steps).
• Automatic calculation of DAR, PI, and DD (dielectric discharge index)
quality ratios.
• Automatic calculation of measurement result referred to a reference
temperature.
■Automatic capacitance measurement.
■Automatic measurement of residual current.

MAXIMUM OUTPUT VOLTAGE
The Model 5070 provides the ability to limit the maximum test voltage to a
value you specify from 40 to 5100 V. When programmed, the instrument will not
generate a higher voltage to conduct the test even if the switch position indicates
a higher voltage. For example, if you set the maximum voltage to 1250 V and
place the rotary switch in the 5000 V position and start a test, the Model 5070 will
only output 1250 V.
Range
40 to 5100 V

the selected measurement voltage. If the V Disturbance exceeds the value of
the ratio, the instrument stops the test in process. If the voltage exceeding the
ratio is present at the device under test before the test is started, a test will not
be allowed to start. Three programmable values are: 3%, 10% and 20% of the
measurement voltage. The default is 3%.

starts will inhibit the test.
