1.3 Probe
1.3.1 Probe safety
Check and obey the rated values of the probe parameters before using it.
A protective cover surrounding the probe main body can prevent fingers from electric
shock.

Connect the probe to the oscilloscope and ground the ground terminal before any
measurement.
Attention:
Keep fingers behind the protective curve on the probe main body to prevent electric shock
when using the probe.
Do not contact the metal part on the top of the probe when the probe is connected to a voltage
source.
The signal measured by the oscilloscope uses ‘‘ground ’’ as reference voltage, and the ground
terminal should be grounded correctly to prevent short circuit.
1.3.2 Probe attenuation setting
The probe has different attenuation coefficients that influence the vertical scale of the
signal. The “ATTENUATION” switch on the probe is ensured to be matched with the
“PROBE” coefficients in the oscilloscope.
Manually set the probe options, press down the vertical menu key, and then select the
“PROBE” option (such as [CH1]
→
“PROBE”).
