How To Implement The Probe Compensation - Owon FDS Series User Manual

(2) Turn on the channel output, then ensure the channel is in Constant
Voltage output mode.
(3) Set some different voltage values on this channel; check if the actual
voltage value displayed is close to the set voltage value, and also that the
actual current value displayed is nearly to zero.
(4) Check CH1 and CH2 channel if the output voltage can be adjusted from
0.1V to the maximum rating.
2. Current Output Inspection
The following steps check basic current functions with a short across the
power supply's output:
(1) Power on.
(2) Connect a short across (+) and (-) output terminals with an insulated test
lead on this channel. Use a wire size sufficient to handle the maximum
current.
(3) Set the output voltage to the maximum rating on this channel.
(4) Turn on the channel output. Ensure the channel you used is in Constant
Current output mode.
(5) Set some different current values on this channel; check if the actual
current value displayed is close to the set current value, and to check if the
actual voltage value displayed is nearly zero.
(6) Check CH1 and CH2 channel if the output current can be adjusted from
zero to the maximum rating, When it is set to the maximum or minimum, a
beep is heard, indicating that the limit has been reached.
(7) Turn off the channel output and remove the short circuit from the output
terminals.

How to Implement the Probe Compensation

When connect the probe with any input channel for the first time, make this
adjustment to match the probe with the input channel. The probe which is not
compensated or presents a compensation deviation will result in the
measuring error or mistake. For adjusting the probe compensation, please
carry out the following steps:
1. Set the attenuation coefficient of the probe in the menu as 10X and that of
the switch in the probe as 10X (see "How to Set the Probe Attenuation
Coefficient" on P13), and connect the probe with the CH1 channel. If a
probe hook tip is used, ensure that it keeps in close touch with the probe.
Connect the probe tip with the signal connector of the probe compensator
and connect the reference wire clamp with the ground wire connector of
