4. Installation
a. Simply plug-in the BNC output connector to the vertical input of a general purposed
oscilloscope or other measurement instrument. The measurement instrument must be
ground referenced.
b. Connect an appropriate power source to the probe or enter the batteries, then turn it on.
c. Select the proper attenuation ratio. When measuring signals below 70 V or 140 V, switch
the attenuation ratio to 1/10 (RT-ZD002) or 1/20 (RT-ZD003) in order to get higher resolution
and less noise. Otherwise, set the attenuation ratio to 1/100 (RT-ZD002) or 1/200
(RT-ZD003) when measuring signals up to 700 V or 1400 V.
WARNING. To protect against electric shock, use only the
accessories supplied with this probe.
d. Using the appropriate probe accessories, connect the inputs to the circuit under test.
CAUTION. This probe is built to carry out differential measurements
between two points on the circuit under test.
This probe is not meant for electrically insulating the
circuit under test and the measuring instrument.
5. Appearance
The differential probe looks as follows.
a. Output cable
The BNC output connector and an auxiliary grounding
terminal are connected to the oscilloscope.
b. Input leads
The input leads of the differential probe connect to
appropriate accessories with 4 mm sockets.
c. Connection accessories
The accessories are connected safely to test points in the
circuit under test.
