The Phase Multimeter SICO 2074 combines two AC voltage meters, a frequency meter, and a phase meter in a firm and lightweight housing.
The phase measurement refers to the fundamental components (Sinus form) of both AC voltages.
Thanks to an elaborate meter technology convenience and safety are perfectly combined.

Overview of the features

  • two independent but simultaneously working AC voltage meters

  • both inputs are entirely electrically isolated

  • highest protection against contact (even electrically isolated battery box)

  • simultaneous display of voltage, frequency, and phase angle

  • convenient wave form report for both channels

  • frequency range up to 10000 Hz, voltage up to 300V

  • to choose from ±180° or 360° display

  • large illuminated LC display

  • extra high wave form tolerance and immunity against interference by the use of virtual selective reference (vsr) phase measurement

  • sturdy housing, which is resistant to environmental influences

  • universal accessory for further connections

Note for users in the field of railway signalling and safety systems:

The Phase Multimeter SICO 2074 is used for the testing and start-up of track circuits with phase evaluation up to 10 kHz (i.e. two layer and three layer motor-driven relays, and valve track circuit relays).

It replaces the Phase Angle Meter PSM 100 and the Phase Angle Tester PWP 1000.
