Step
Action
 
1.
Connect the Probix adapter of an HX0030 probe
having a 1/10 ratio to the CH1 input.
2.
Connect the probe (with its ground) to the calibrator
output (Probe Adjust:
≈3
V,
≈
1kHz) on the side of the
instrument.
Connect the cold of the probe to the cold of the
calibration output of the probes.
4.
Check that the 1/10 coefficient of the probe has in
fact been taken into account.
