METRAPHASE 1
Phase Sequence Indicator

2/8.99
GOSSEN-METRAWATT GMBH
Applications
Phase sequence, line frequency and phase voltage are tested
and displayed simultaneously after the METRAPHASE 1 test
instrument has been connected to the system under test at all
phases with the included, contact-protected connector cables.
The instrument is suited for initial testing, as well as for testing
after repairs and modifications.
Features
Convenient Testing with Only 2 Cables (2-pole measurement)
In addition to normal testing with 3 measurement cables, phase
sequence can also be tested with only 2 cables. After connection
to L1 has been established, phases L2 and L3 are scanned
separately, one after the other.
This operating mode is indicated by means of intelligent software
which rules out the possibility of erroneous measurements.
Automatic Activation
The instrument is activated automatically as soon as a voltage of
at least 100 V is applied to any 2 measurement sockets.
Battery Saving Circuit
The instrument is shut down automatically when zero voltage is
applied in order to extend battery service life.
