HV test meter multiplier >Project by Geo

10ea 99 Megs in series, 1/10%

 

990 MegOhms
Goes in series with 10 Meg DVM to measure HV in Geiger Counters with precision, without loading down the high impedance circuits. Total 1000 MegOhm including the meter resistance for a X100 multiplication factor on voltages read.
I use one with a dedicated panel meter that has 0-20 Volts full scale= 0-2000V.

 

Regular DVMs can't be used to measure the HV on a Geiger Counter because they will load down the extremely high impedance circuits and give unrealistically low readings. . At least 100 MegOhms is required, and 1000 MegOhms is best.

 

This is not an offer to sell these kits, they are all gone now. Use the information to construct your own version or contact author for advice.
