Page 15: Operating Procedure
Preparations for Measurement CAUTION 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. -
Page 16: Demagnetizing And Zero Adjustment
• Do not demagnetize when the clamp is connected to a conductor. Doing so might damage the components of the circuit being measured. • Do not begin supplying power to the 701930 after the clamp has been connected to a conductor. Doing so might damage the components of the circuit being measured. -
Page 17: Measurement Procedure
• At high ambient temperatures, the built-in safety circuit may activate at current input levels below the rated continuous maximum. • Continuous input of current exceeding the rated maximum, or repeated activation of the safety function may result in damage to the unit. IM 701930-01E... - Page 18 It is now possible to monitor the current waveform. The output voltage rate of the 701930 is 0.01 V/A. Convert the voltage sensitivity of the waveform observation instrument to current sensitivity. For example, if the voltage sensitivity is 10 mV/DIV, the current sensitivity is 1 A/DIV.
- Page 19 • Accurate measurement may be impossible in locations subject to strong external magnetic fields such as transformers and high-current conductors, or in locations subject to strong external electric fields such as radio transmission equipment. IM 701930-01E...
