1
Nominal resistance values.
2
Nominal currents. Calculate actual currents from calibrator voltage and actual standard resistor value: I = V/R. Calibrate zero, posi-
tive full-scale, and negative full-scale for each range. Triax cap used for zero cal points.
3
Allow calibration signal to settle for indicated time before calibrating each point.
