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
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).
