Handling Precautions

Preparations for Measurement

1-4
• Do not clamp bare conductors to avoid short circuits or personal injury
when the sensor head is open or measuring.
• Be careful not to damage the insulation surface of the conductor under
measurement.
• Do not short-circuit between the two measurement lines with the metal
part of the sensor unit. It may lead to a serious accident such as the
occurrence of an arc.
• Connect the power supply to the probe power terminal (option) of a
waveform measuring instrument such as Yokogawa DL/DLM series, or
use the power supply 701934 or 700938.
• Be careful of electric shock when connecting the probe to the device
under measurement.
• Read and observe the safety precautions of the instruments to be
connected to.
• To avoid electric shock, do not get the instrument wet or use it with wet
hands.
When using a 701930 current probe, it may not be possible to use multiple
active probes at the same time with the 701934, 700938 power supply,
or the probe power supply from a YOKOGAWA waveform measuring
instrument. Make sure that the total current consumption of each active
probe does not exceed the current specifications of the probe power
supply. The current consumption of the probe depends on the measured
current (refer to the figure below).
See the following YOKOGAWA website for the usage limitations for each
measuring instrument.
