5000V Graphical Megohmmeter Model 5070

The Model 5070, the latest design in
5000V Megohmmeters, is the most
innovative product in its class on the
market today. The features and
functions incorporated in this product
are the results of many years of
analyzing how megohmmeters are
used in everyday applications. The
most advanced technology available
has been applied to automate and
facilitate the testing process for these
applications.

Many features incorporated in the
Model 5070 (not found in any other
megohmmeter on the market today)
include automatic calculation and
presentation of the Dielectric
Absorption Ratio (DAR), Polarization
Index (PI) and Dielectric Discharge
(DD). The PI ratio times are also user
defined. This new ad vanced
megohmmeter displays the test
voltage, insulation resistance and
the leakage current during and
after the test.

Capacitance of the sample and
discharge voltage present at the test
leads is displayed at the conclusion of
the test. The Model 5070 is the only
megohmmeter to offer both a graphical
plot of the test right on the instrument,
as well as a digital presentation of the
test results. The Model 5070 also offers
the ability to program up to three step
voltage profiles, each containing up to
five steps.

The Model 5070 is designed with the
highest level of safety features built in.
The unit is packaged in a rugged
insulated case. The Model 5070
incorporates test inhibit capabilities
which will not allow test voltages
to be generated if a live sample is
detected. The test terminals are
recessed to ensure operating safety.
The test leads, rated for 5000V for both
testing and measurement, are the only
truly safety approved 5000V leads on
the market today. The Model 5070 can

5000V Graphical Megohmmeter Model 5070 (pdf) Rev. 06 02/08

be operated from an internal
rechargeable battery system or from
AC line power.

The Model 5070 offers additional
functionality in that an RS-232 port
provides the ability to configure the
units from a PC and run the test from
the PC. Automatic documentation of
test conditions and test results
eliminates the need for writing down
information. Test reports can be
generated directly from the instrument
to a printer or through the PC using the
DataView
software provided.

The list of features, functions and
benefits goes on and on. If you are
looking for a truly advanced 5000V
Megohmmeter, the AEMC Model 5070
is the best in class and available at an
affordable price.

Insulation can be subject to slow, gradual degradation
over long periods of time, as well as sudden damage.
The effects of moisture, dirt, corrosion, chemical
penetration and even vibration can cause degradation
of insulation. The effects of this degradation can easily
be documented by using the automatic Polarization
Index test feature standard on all models. Comparing
the results over time will provide valuable information for
preventative maintenance measures.

Key Functions

Smooth Function – This function is very

useful when the readings on the display are
unstable and hard to read. It applies a digital
filter to the displayed readings to smooth out
the presentation. It does not effect the
measurement or recording of data.

Alarm Function – Allows for the setting of a

low limit resistance value for each test voltage,
below which a buzzer will sound alerting you to
a problem condition.

Selectable Voltage – Provides the flexibility

to program an exact voltage for a specific test
to any voltage from 40 to 5100V in 10V
increments. The Model 5070 also allows for
storage of three different voltage selections.

Test Voltage Lock-out – Gives the flexibility

to limit the maximum output test voltage to
any value from 40 to 5100V to protect delicate
equipment from accidental exposure to
excessive test voltages.

Timer Function – Program a test run time

from one minute to 50 hours.

Record Function – provides the option to

automatically store the data from a timed test
at programmable intervals or to store the
results of the test manually at the push of
a button at the end of the test.

Print Function – Provides a direct print

out to a printer of test results in a predefined
format.

Graph Function – Provides a graphic

representation of a time test on the display of
the Model 5070 of insulation resistance vs. time.
If the step voltage mode is selected, the step volt­age is also shown graphically.

Ramp Function – Allows programming of three

different ramp test profiles, each containing up to
five voltage steps between 40 and 5100V and
time per step of up to 10 hours.

Temperature Function – Provides the ability

to display insulation resistance temperature
corrected to a specific reference temperature.
