Hi,
I am trying to measure the output of 10kV DCDC converter (EMCO F101).
The output runs through a voltage divider:
V+(out) DCDC
|
|
120MOhm
|
|
10kOhm
|
|
V-(out) DCDC
I measure voltage across 10kOhm resistor with digital multimeter (MS8264, 10MOhm impedance). In a test case, I apply 2V input to DCDC and expect 2/15*10kV=1333V output. Thus I expect voltage across 10kOhm to be 10E3/(120E6+10E3)*1333=111mV. However, the dmm measured 186mV.
What is the reason for the discrepancy? Is there a better way to measure the output?
