Must be grounded
This probe is grounded with the shell of BNC connector and an auxiliary grounding terminal,
through the grounding conductor of the power cord of the measurement instrument.
Before making connections to the input leads of this probe, ensure that the output BNC connector
is attached to the BNC connector of the measurement instrument and the auxiliary grounding
terminal is connected to a proper ground, while the measurement instrument is properly
grounded.
Use fused test prods if necessary
If this probe is intended to use for measurements in circuits of INSTALLATION CATEGORY III,
it should incorporate with fused test prods.
Do not operate without covers
To avoid electric shock or fire hazard, do not operate this probe with covers removed.
Do not operate in wet/damp conditions
To avoid electric shock, do not operate this probe in wet of damp conditions.
Do not operate in explosive atmosphere
To avoid injury or fire hazard, do not operate this probe in an explosive atmosphere.
Avoid exposed circuit
To avoid injury, remove jewelry such as rings, watches, and other metallic objects. Do not touch
exposed connections and components when power is present.
Use proper power source
To ensure this probe function well, use four AA cells or 6VDC/90mA or regulated 9VDC/70mA
mains adaptor or power lead.
Do not operate with suspected failures
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, the differential probe extends the measurement
capability of oscilloscopes in 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 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 (mains adaptor, battery pack or power lead) to this
probe and then turn it on.
WARNING. To protect against electric shock, use only the
accessories supplied with this probe.
c. Using the appropriate probe accessories, connect the inputs to the circuits under
measurement.
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.

a. The supplied voltage must be less than 16V and greater than 3.3V, otherwise the probe could
be damaged or can’t be operated properly.
b. For wrong polarity of power sources, a built-in circuit will protect the probe and no danger or
damage will occur.
c. When the voltage of the cells become too low, the power indicator on the panel will dim and
then distinguish.

9. Inspection Procedure
a. Connect the BNC output connector to the vertical input of a general purposed
oscilloscope.
b. Connect an appropriate power source to this probe and then turn it on.
c. Set the oscilloscope to DC coupling and 1V/div. Center the trace on the display.
d. Connect the inputs of the probe to power lines.
e. Then, a 50Hz/60Hz sine-wave of proper amplitude will be displayed on the screen of
the oscilloscope and this means the probe is working properly.
10. Cleaning
Use a soft cloth to clean the dirt. Prevent damage to probe.
a. Avoid immersing the probe.
b. Avoid using abrasive cleaners.
c. Avoid using chemicals contains benzene or similar solvents.
