Applications
The CP 30, CP 330, CP 1100 and CP 1800 AC / DC current
probes have been designed for reliable and accurate, contactless
measurement of AC, DC and complex waveform currents.
Their special characteristics make these current probes high-per-
formance instruments for the measurement of inverters, swit-
ched-mode power supply units, industrial control systems and
other applications which require current measurement or wave-
form analysis.
Features
Auto Power OFF
The device is switched off automatically after approx. 10 minutes
if none of its keys have been activated during this time. Automatic
shutdown can be deactivated.
