The CA6525 Megohmmeter Insulation Tester is designed to be straight forward and convenient for measurement with is giant backlit display. It has a number of measuring aids. It has a programmable high and low thresholds trigger 'beep' sound, meaning there is no longer need to read the values to verify the result. It also has a timer function which can automatically measures time with a stop watch display. The CA 6525 also has lead compensation meaning precise measurement in continuity is guaranteed.
