To avoid injury, death of personnel or damage to the instrument, the operator must refer to an explanation in the User's Manual or
Service Manual.
• Grounding of the measuring instrument
The protective grounding terminal of the measuring instrument must be connected to ground.
• Earth cable of the probe
Make sure to connect the earth cable of the probe to the ground (grounding potential).
• Connecting the object of measurement
Make sure to avoid an electric shock when connecting the probe to the object of measurement. Do not remove the probe from
the measuring instrument after the object of measurement is connected.
• Do not operated with suspected failures
If you suspect that there is damage to this probe, have it inspect by a service personnel.
• Observe maximum working voltage
To avoid any injury,do not use the probe above 1400Vpeak between each input lead and earth or between the two inputs.
This voltage rating applies to both 1/100 and 1/1000 settings.
• Must be grounded
This probe must be grounded with the BNC shell and an auxiliary grounding terminal, through the grounding conductor of the
power cord of the measuring instrument or other appropriate grounding conductor.
Before making connections to the input terminals of the product,ensure that the output connector is attached to the BNC
connector of the measuring instrument and the auxiliary grounding terminal is connected to a proper ground,while the
measuring instrument is properly grounded.
• Do not operate without cover
To avoid electric shock or fire hazard,do not operate this probe with the cover removed.
• Do not operate in wet/damp conditions
To avoid electric shock,do not operate this probe in wet or damp conditions.
• Do not operate in explosive atmosphere
To aviod 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.
• Maximum input voltage
Do not apply any voltages exceeding the maximum input voltage to the probe.
• Correct use of the power supply
Power the probe with either 4 AA dry cells, a 6 VDC/200 mA or 9 VDC/150 mA external power supply, or by connecting the
probe's power cable to a probe power supply terminal on a DL series measuring instrument or to the 700938 or 701934.
Operating the probe under a power supply greater than the voltage specified above may cause damage to the instrument.
• Connecting the external power supply to the probe
Always turn OFF the probe's power switch when connecting or disconnecting the external power supply.
Also, do not install AA batteries when using an external power supply.
