Using the Probe

WARNING

Concerning the Oscilloscope or Voltage Measuring Instrument to Which the Probe is

Connected

Whenever it is likely that the ground protection is impaired, you must

make the instrument inoperative and secure it against any unintended

operation.

If you energize the instrument by an auto transformer (for voltage

reduction or mains isolation), the ground pin of the input connector

terminal must be connected to the earth terminal of the power source.

Before turning on the instrument, you must connect the protective earth

terminal of the instrument to the protective conductor of the (mains)

power cord. The mains plug shall only be inserted in a socket outlet

provided with a protective earth contact. You must not negate the

protective action by using an extension cord (power cable) without a

protective conductor (grounding). Grounding one conductor of a

two-conductor outlet is not sufficient protection.

Only fuses with the required rated current, voltage, and specified type

(normal blow, time delay, etc.) should be used. Do not use repaired fuses

or short-circuited fuse holders. To do so could cause a shock or fire

hazard.

Capacitors inside the instrument may retain a charge even if the

instrument is disconnected from its source of supply.
