2.1 Intended Use / Use for Intended Purpose
The instrument is a phase sequence indicator with elec-
tronic rotary dial, frequency display and nominal line volt-
age display.
Note!
It’s not a voltmeter in the usual sense of the word –
it only indicates voltage within the specified ranges.
Safety of the operator, as well as that of the instrument, is
only assured when it’s used for its intended purpose.
2.2 Use for Other than Intended Purpose
Use of the instrument for any purposes other than those
described in these operating instructions is contrary to use
for intended purpose.

3InitialStartup
Batteries
The phase sequence indicator is shipped ready to use with
four AA batteries. Before initial startup, be sure to read
section 7.1, “Battery”.
Battery Test
If none of the LEDs light up after applying voltage, or if
they’re very dim, the batteries need to be replaced.
Switching the Instrument On Automatically
The instrument is switched on automatically when a volt-
age of at least 100 V is applied to 2 measuring sockets.
Automatic Shutdown
The instrument is switched off automatically when voltage
is no longer applied. Battery service life is extended in this
way.
4Operation
Attention!
!
Measurements per DIN EN 61010-031 may only
be performed in environments in accordance with
measuring categories III and IV with the safety cap
attached to the test probe at the end of the mea-
surement cable.
Note!
In order to establish contact inside 4 mm sockets,
the safety caps have to be removed by prying open
the snap fastener with a pointed object (e.g. the
other test probe).
Note!
The phase sequence indicator does not include
any fuses!
4.1 Voltage Display
Voltage is displayed by means of 3 red LEDs (5) which are
allocated to the respective nominal line voltages. The high-
est voltage which occurs within the circuit between two
phases is always detected.
Voltage is displayed for nominal voltages 120 V/208 V,
230 V/400 V and 400 V/690 V.
Missing or Unconnected Phase
If one of the phases isn’t connected to the phase
sequence indicator, or if it isn’t included in the wiring, its
potential is too small relative to the artificial neutral point.
The corresponding phase LED does not light up in this
case. However, the voltage value LED lights up in accor-
dance with line-to-line voltage.

GMC-I Messtechnik GmbH 9
GB
Special case: If the phase is missing at the L1 connector
socket, the voltage value LED indicates the next lower volt-
age because in this case the instrument no longer has an
internal reference point.
Attention!
!
The L1 socket on the METRAPHASE 1
must always be contacted first
in order to prevent erroneous measurements.
4.2 3-Pole Connection
Symmetrical Clockwise Rotation
If symmetrical clockwise rotation is measured, phase LEDs
L1, L2 and L3 are continuously lit up and an illuminated
green spot (rotary LED) rotates in the clockwise direction
around the display loop (approx. 30 RPM).
Symmetrical Counterclockwise Rotation
In the case of symmetrical counterclockwise rotation,
phase LEDs L1 through L3 light up as well, but color and
direction of the rotating spot are changed: it rotates in the
counterclockwise direction and lights up red.
Frequency Display
In the case of clockwise rotation, the LED assigned to the
momentary frequency briefly lights up red, as soon as the
illuminated rotating spot passes its position. In the case of
counterclockwise rotation, the corresponding LED lights
up green.
Instrument Sockets Connected to N or PE
If one of the sockets is connected to N or PE, the LED for
the incorrectly connected phase doesn’t light up. Phase
sequence indication is the same as for clockwise or coun-
terclockwise rotation.
Incorrect Wiring
If wiring has not been completed correctly, e.g. 2 x L1,
indefinite displays can be expected.
4.3 2-Pole Connection
ABC

10 GMC-I Messtechnik GmbH
Phase sequence can also be determined with just 2 con-
nector cables if line frequency is 50 or 60 Hz:
1 Contact phase L1 first via connector socket L1 and
then connect phase L2 via connector socket L2 (see
figure A).
Phase LEDs L1 and L2, as well as the corresponding
voltage value LED, light up red. The two LEDs for 100
and 400 Hz also light up. This indicates that the instru-
ment has synchronized itself to phases L1 and L2.
2 Disconnect socket L2 from phase L2 (see figure B).
The two LEDs for 50 and 200 Hz light up during this
standby mode.
3
Now connect phase L3 via the L2 socket (see figure C).
Phase LEDs L1 and L3 light up red. L2 is generated in-
ternally. Phase sequence and line voltage value can be
read from the display.
Note!
Changing from L2 to L3 must be completed within
approximately two seconds. If this duration is
exceeded, the instrument is no longer able to
maintain synchronization with the mains. The 60,
100, 300 and 400 Hz LEDs light up simultaneously
to indicate that this is the case. The 100 and
400 Hz LEDs then light up, in order to indicate that
2-pole measurement has been restarted. The
same display sequence is used in the event that
the same phase is contacted again erroneously
instead of changing from one phase to the other.
