This section provides maintenance information for the probe.
Troubleshooting
LED status lights on the probe can indicate the current probe status or errors. If the
probe LED status light does not glow as expected, or if some function of the probe is
not working properly, there may be an error. See the table below.
Table 6: Probe Troubleshooting
Malfunctions
Possible Cause
Degaussing and auto-zero failed
The wire claw is not locked;
The probe is clamped on the working
circuit under test when the probe is
degaussing and zero.
Unable to measure DC signal
Check whether the probe is powered
properly;
Check the oscilloscope coupling method.
The amplitude of the measurement signal
is too small.
Check whether the input impedance of the
oscilloscope is 50Ω. Please adjust it to
1MΩ to work
properly.
LED status light does not glow
The oscilloscope channel may be damaged,
please try to replace other channels or
other oscilloscopes. After plugging in the
oscilloscope, all LED status lights should
light up for a short time; if the probe works
normally on other channels or oscilloscopes,
it is considered to be caused by the
oscilloscope channel and has nothing to do
with the probe; If the probe does not work
on other channels or on the oscilloscope,
the probe may be defective, please contact
the Micsig after-sales department for repair.
