2. PRODUCT FEATURES
2.1 DESCRIPTION
The Model 5070 megohmmeter is a top-of-the-line measuring instrument,
portable, in a rugged housing with a graphic display. It is capable of operating
from internal battery or line power.
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.
This megohmmeter helps ensure the safety of electrical installations and
equipment. The operation is controlled by a microprocessor for data acquisition,
processing, display of measurements, and storage of results.
Advantages:
Automatic voltage measurement.
Automatic detection of external AC or DC voltages on the terminals, before
or during insulation measurements, disabling or stopping the measurements
when measurement accuracy is no longer guaranteed.
Threshold programming to trigger audible alarms.
Timer for measurement time checks.
Fuse protection of the instrument with detection and display of defective fuses.
Operator safety by automatic discharge of residual high voltage on the
equipment tested.
Automatic shutdown of the instrument to save battery power.
Battery charge indication.
Large backlit graphic display that is very easy to read.
Memory (128 kB), real time clock, and serial interface.
Control and programming of the instrument from a PC (using DataView software).

device under test. This will be used when temperature correction is applied if no
value is programmed right after the test is conducted.

Insulation resistance changes with temperature. The typical rule of thumb is that
for every 10°C increase in temperature the leakage current doubles and the
the equipment you will be testing. This value will be used when correcting results
to a reference temperature.

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.

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%.
If a test is to be performed at 1000 V and the V Disturbance / V Output
is set at 10%, the presence of 100 volts (1000 V * 10% = 100) before the test
starts will inhibit the test.
