Getting Started
1.
Connect the BNC output connector to the vertical input of
a general purposed oscilloscope or other measurement
instrument. The measurement instrument must have a ground
referenced.
2.
Connect power source.
3.
Select the proper attenuation ratio. When measuring signals
below 70 V, switch the attenuation ratio to 10x in order to get
higher resolution and less noise ratio. For voltages up to 700 V,
set the attenuation ratio to 100x.
4.
Plug the hook probes onto the test leads and connect the circuit
to be tested.
5.
Slide the power switch on the probe to the “ l ” position. The
indicator will light up.
CAUTION
This probe is used to carry out differential measurements between
two points on the circuit under test. This probe is not designed for
electrically insulating the circuit under test or the measuring instrument.
