Description

A precision instrument suitable for calibrating and testing general purpose insulation

testers and megohmmeters with test voltages up to 2.5 kV. It is constructed in a high

strength co-polymer plastic case and is powered by a rechargeable battery. This ensures

full isolation from the mains and prevents stray leakage.

The insulation tester being calibrated can be tested for open circuit voltage and short

circuit current. These are displayed on the digital meter mounted on the front panel. Nine

selectable precision resistors provide the insulation resistance test. Also fitted are 4 fixed

low resistance values for verification of the low ohm ranges and continuity. Rugged,

compact and portable, the 5068 is easy to transport and ideal for site calibration work.

Also available is the 5069, 10 kV version.
