Display Values in Consideration of Measuring Uncertainty
Table for determining minimum display values for insulation resistance in
consideration of the instrument’s measuring uncertainty.
Table for determining maximum display values for low-value resistance
in consideration of the instrument’s measuring uncertainty.
Voltage at Device Under Test During Insulation Resistance
Measurement
Measuring voltage Ux at the device under test depending upon its
resistance Rx at nominal voltages of 10, 100 and 500 V:
