4. Installation
a. Simply plug-in the output BNC connector of this probe 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. Install four AA cells or connect an appropriate power source to this probe.
c. Select the proper attenuation ratio. When measuring signals below 700V, switch the
attenuation ratio to 1/100 in order to get higher resolution and less noise ratio. Otherwise,
set the attenuation ratio to 1/1000.

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 circuits under
measurement.
________________________________________________________
CAUTION. This probe is 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.
5. Appearance
The differential probe looks as follows.
a b c
a. Output Lead 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 sprung hooks
that come with the probe.
c. Sprung Hooks The sprung hooks are connected safely to test points in circuits
under measurement.
