What are the general safety precautions for handling the probe?
Make sure to comply with the safety precautions mentioned hereafter when handling the probe. YOKOGAWA ELECTRIC Co. assumes no responsibility for any consequences resulting from failure to comply with these safety precautions. Also, read the User’s Manual of the measuring instrument thoroughly so that you are fully aware of its specifications and handling, before starting to use the probe.
How should the measuring instrument be grounded?
The protective grounding terminal of the measuring instrument must be connected to ground.
How should the probe be connected to the object of measurement to avoid electric shock?
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.
What should be done if damage to the probe is suspected?
If you suspect that there is damage to this probe, have it inspect by a service personnel.
What is the warning regarding nondestructive input voltage range?
Do not apply any voltages exceeding ±40 V(DC+AC peak) between input and earth.
What grounding steps are necessary before connecting the probe’s input terminal?
Before connecting the input terminal of the probe to the object of measurement ensure that the measuring instrument is properly grounded and that the probe’s output connector is attached to the BNC connector of the measuring instrument.
Why should the probe not be operated without its cover?
To avoid electric shock or fire hazard, do not operate this probe with the cover removed.
Can the probe be operated in wet or damp conditions?
To avoid electric shock, do not operate this probe in wet or damp conditions.
Can the probe be operated in an explosive atmosphere?
To avoid injury or fire hazard, do not operate this probe in an explosive atmosphere.
What precautions should be taken to avoid injury from 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.
What is the caution regarding nondestructive input voltage range for the probe?
Do not apply any voltages exceeding the Nondestructive input voltage range to the probe.
What type of power source should be used for the probe?
Use the power supply connector for the probe of DL series or use the 700938 power supply. Do not operate this probe from a power source that applies more than the voltage specified.

How do you operate the differential probe?
1. Connect the power supply probe of the product to the power supply connector of DL series or to 700938.
2. Simply plug-in the BNC output connector to the vertical input of a oscilloscope. In this case set the input resistance of the oscilloscope to 50 Ω.
3. Using the appropriate probe accessories, connect the input to the circuits under measurement.
What are the warnings regarding probe operation?
To protect against electric shock the ground side of the output cable (the shielded side of the BNC connector) must be grounded.
When disconnecting the BNC connector, always first separate the probe from the high voltage parts of the circuit under measurement.
How should the probe be cleaned?
Use a soft cloth to clean the dirt. Prevent damage to the probe.
Avoid immersing the probe. Avoid using abrasive cleaners. Avoid using chemicals contains benzene or similar solvents.
What does the “Note” symbol indicate in this manual?
The “Note” symbol indicates information that is important for proper operation of the instrument.
What might affect accurate measurements with the probe?
