Testec TT-SI 9001 Mode D'emploi page 12

4. Installation
a. Simply plug-in the BNC output connector to the vertical input of a general purposed
oscilloscope or other measurement instrument, and connects the auxiliary grounding
terminal to a proper ground. The measurement instrument must have a ground referenced.
b. Connect an appropriate power source to this probe and or enter the batteries, then turn it
on.
c. Select the proper attenuation ratio. When measuring signals below 70V, switch the
attenuation ratio to 1/10 (TT-SI 9001) or 1/20 (TT-SI 9002) in order to get higher resolution
and less noise ratio. Otherwise, set the attenuation ratio to 1/100 (TT-SI 9001) or 1/200
(TT-SI 9002) when measuring signals up to 700VDC (TT-SI 9001) or 1400VDC (TT-SI 9002)
d. Using the appropriate probe accessories, connect the inputs to the circuits under
measurement.
5. Appearance
The differential probe looks as follows.
a. Output Cable
b. Input Leads
c. Sprung Hooks
WARNING. To protect against electric shock, use only the
accessories supplied with this probe.
CAUTION. This probe is to carry out differential measurement
between two points on the circuit under measurement.
This probe is not for electrically insulating the circuit
under measurement and the measuring instrument.
The BNC output connector and an auxiliary grounding terminal
are connected to the oscilloscope.
The input leads of the differential probe connect to sprung hooks
that come with the probe.
The sprung hooks are connected safely to test points in
circuits under measurement.
