Atec OMICRON-CP-AL1 - Manual

CP AL1
FFT Voltmeter (Fast Fourier Transformation)
The CP AL1 is used in conjunction with the CPC 100 and
CP CU1 to measure step and contact voltages.
The CPC 100 and CP CU1 can be used to feed signals into
power lines or overhead lines to simulate fault currents.
Step and contact voltages are now easy to measure at various
locations using the mobile CP AL1 handheld device.
The CP AL1 is supplied with special OMICRON software that
enables measurement of frequency-selective voltage levels
through the use of a real-time zoom FFT.
The standardized 1 kΩ testing resistors for body and shoe
resistance, as prescribed by relevant standards, are already
fitted in the connection adapter of the CP AL1. This allows
uncomplicated measurement of step and contact voltages as
per the DIN VDE 0101 regulation.
