electrometer circuit

Need schematic for an electrometer.
Thx
 


high voltage probe schematic

Thx to all! But I need a more precise instrument and instructions for calibration of the same in the range 0..5kV and 0..15kV!
Thx

The stuff you need is a high voltmeter, not an electrometer.

Do you really need an electrometer, or simply a high-voltage meter? What input resistance to you require?

Please clarify "more precise". How precise?

A high voltage meter can be as simple as buying a high-voltage probe that plugs into an ordinary DVM. Example Fluke 80K-40:

That probe uses a simple voltage divider made from two resistors. The schematic is in the Instruction Sheet.
 

simple electrometer

I really need an electrometer which is capable of measuring electrical field. I need it to measure voltage of human body for ESD testing. The input impedance Rin=infinite.
The precision requred is 5%.
 

ina116 resistance measure

Yeah, that is really electrometer.

However, as it is related to human safety, you should buy one, it is not expensive, rather than build by yourself. It is very dangerous for you, both by the circuit itself and the safety law.

high voltage probe for electrometer

You can use INA116 for very high input impedance amp (10E15Ω) and bootstrap it to desired voltage. Although, getting accurate measurements might be very difficult even for very experienced engineer and every aspect of design would be critical. If you don't have really a lot of time to burn, buy Kethley or some other electrometer as suggested.\][/u]
