2. General safety summary
Please review the following safety precautions to avoid injury and prevent damage
to this probe or any products that are connected to it.
Observe maximum working voltage
To avoid any injury, do not use the probe above 40 V between each input lead and
earth or between the two inputs..
Do not operate without covers
To avoid electric shock or fire hazard, do not operate this probe with the covers
removed.
Do not operate in wet or damp conditions
To avoid electric shock, do not operate this probe in wet or 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 circuitry
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 proper functioning of this probe, use the 15 V DC / 100 mA regulated
mains adaptor. Do not operate this probe from a power source that applies more
than the voltage specified.
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.

9. Test procedure
a. Connect the BNC output connector to the vertical input of a general-purpose
oscilloscope.
b. Connect the AC mains adapter.
c. Set the oscilloscope input coupling to DC and 0.5 V/div. Center the trace on
the display.
d. Connect the input pins of the probe to a function generator and select a
square-wave output with 10 V p-p amplitude and 100 kHz frequency.
e. A 100 kHz square-wave of 1 V p-p amplitude will be displayed on the screen of
the oscilloscope. This means the probe is working properly.
10. Cleaning
Use a soft cloth to clean the probe, taking care not to cause damage.
a. Do not immerse the probe.
b. Do not use abrasive cleaners.
c. Do not use chemicals contains benzene or similar solvents.

With high bandwidth and high CMRR, this differential probe is ideal for timing
analysis, troubleshooting ground bounce problems in high-speed logic, and design
verification of disk drives, as well as for wireless and data communications design.
4. Installation
a. Simply plug in the BNC output connector to the vertical input of a
general-purpose oscilloscope.
b. Connect the AC mains adaptor to the correct line voltage, and then connect its
output to the power terminal of the differential probe.
c. Adjust the vertical offset (or position) of the oscilloscope.
