7. Probe Compensation
Before working the probe with either of input channels (Channel 1 / Channel 2), better to
adjust its compensation, to assure ideal measurement effect. Since the probe in
non-compensated, or improperly-compensated (overcompensated / under-compensated)
status always possibly cause error or mistake of measurement result.
Following operation steps to adjust probe compensation -
i. From PC software operation interface, mouse-click
function menu, choose "Channel", then "CH1", set the "Probe Rate" as "x10". Switch
probe attenuation to X10 option, then get the probe through Channel 1 input via device
communication interface. Provided introducing a probe hook tip, make sure it is in close
touch with the probe. Connect the probe tip with the signal output coupler of probe
compensator, and connect the reference wire clamp with the ground wire coupler of the
probe compensator, and then click

ii. The probe compensation goes in 3 different status (as Figure 7- 2 shows),
Overcompensated
provided probe in overcompensated or under-compensated status, use probe adjust (from
device accessories) to adjust the screw (leftwards or rightwards) of probe body (Figure 7- 3).
For different brand-new probe, please repeat these steps to get ideal compensation.
