Re: Comark Early 1905 Insulation Meter Checks
Hi jimmc 101 and Bazz4CQJ
My Dad's Comark 1905 has discrete components inside and not the later op amp. It has been looked after with no scratches or dents on the bodywork.
Have connected my Fluke 179 true RMS multimeter across the terminals with the results below.
Cal FSD
25v gives 20.73
50v gives 34.33
100v gives 51.4
250v gives 73.1
500v gives 85.6
1000v gives 93.8
The meter does seem to show 10MegOhm but would like to know if the readings are what should be expected for this meter? Thanks for all your help on this old meter but would like to use it for checking shorts or leakage on heating elements.
