2. General Safety Summary

Review the following safety precautions to avoid injury and prevent damage to this probe
or any products that connected to it.

Observe Maximum Working Voltage

To avoid any injury, do not use the probe under the condition that the voltage between
either input lead or earth is above 1000Vrms CAT III. This voltage rating applies to both
settings 1/10 & 1/100.

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 MEAUSREMENT
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/60mA or regulated
9VDC/40mA mains adaptor or power lead. Do not operate this probe from a power source
that applies more than the voltage specified.

Do Not Operated 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 applications.
