a. The supplied voltage must be less than 12 V and greater than 4.4 V, otherwise
the probe could be damaged or might not operate properly.
b. Polarity is “+” inside and “–” outside. If the polarity is wrong, a built-in circuit
protects the probe so that no danger or damage will occur.
c. When the voltage of the cells becomes too low, the power indicator on the
panel will flicker.

Use proper power source
To ensure proper functioning of this probe, use four AA cells or a 6 VDC / 200 mA
mains adaptor or 9 VDC / 120 mA mains adaptor or power leads.
Do not operate the probe if it is damaged
If you suspect there is damage to this probe, have it inspected by qualified service
personnel.
3. Description
By enabling conventional oscilloscopes to display and measure in-circuit waveforms
that are referenced to high common-mode voltages, this differential probe extends
the measurement capability of oscilloscopes to electronic power converters,
inverters, motor speed controls, switch-mode power supplies and many other
applications.
4. Installation
a. Simply plug in the BNC output connector to the vertical input of a
general-purpose oscilloscope or other measurement instrument, and connect
the auxiliary grounding terminal to a proper ground. The measurement
instrument must have a ground reference.
b. Install four AA cells or connect an appropriate power source to this probe.
c. Select the proper attenuation ratio. When measuring signals below 700 V,
switch the attenuation ratio to 1/100 in order to get higher resolution and less
noise. Otherwise, set the attenuation to 1/1000.
WARNING
To protect against electric shock, use only the
accessories designed for use with this differential
probe.
d. Using the appropriate probe accessories, connect the input to the circuits under
measurement.
CAUTION
This probe is designed for carrying out differential
measurements between two points on the circuit
under test. It is not intended for electrically
insulating the circuit under test and the measuring
instrument.
