The
Digital/Analog Megohmmeter Model 5050 is the latest design in 5000V
insulation testers.
Features include automatic calculation and
presentation of the Dielectric Absorption Ratio (DAR), Polarization Index
(PI) and Dielectric Discharge (DD).
The Model 5050 displays the test
voltage, insulation resistance ad the leakage current during the test.
Capacitance of the sample and discharge voltage present at the test leads
is displayed at the conclusion of the test. This meter is designed with
the highest level of built in safety features.
The Model 5050 can be
operated from an internal rechargeable battery system or from an AC line
power.
