m) 3-Phase rotating direction display "Motor"
TheDMMmayidentifytherotatingdirectionina3-phasecurrentnetworkviathemeasuringfunction“Motor”.Only2
measuringlinesareneededtodisplaytherotatingdirection.Duringidentication,theouterconductorsL1,L2andL3
mustbescannedinsequence.TheDMMrecognisesthephaseoffsetandshowstherotatingdirection(rotatingeld)
with an arrow subsequently.
The 3-phase rotating direction display can be chosen only in the AC-V-range.
Proceed as follows to identify the 3-phase rotating direction:
- TurntheDMMonandselectmeasuringfunction”Motor”.
Thedisplayshows“AC”andtheunit“V”.
- Plug the red measuring line into the V measuring jack (E)
and the black measuring line into the COM measuring jack
(D).
- Keepthebutton“SELECT”pressedforapprox.2s.Two
beepsareoutputand the lockicon(H19)will ash.The
automatic measuring range setting is deactivated and the
600 V-range is selected. The display will show approx. 0.0
V
- Connect the black measuring prod to the outer conductor
L3. This connection remains unchanged throughout the
test. Connect the red measuring prod to the outer conduc-
tor L1.
- Once the meter recognises two outer conductors, the nor-
mal voltage will be displayed and the lock icon will remain
lit.
- Now switch the red measuring prod to outer conductor L2
within 5 seconds. If the time for measuring point change
is exceeded, the DMM will interrupt the measurement and
the function must be restarted.
- The meter will evaluate the phase offset of the three sub-
sequently determined outer conductors at correct meas-
uring point change of the red measuring line, and display
the rotating direction via two symbols in the display. The
arrow direction of the symbols shows the respective rotat-
ing direction:
Clockwise = right turning
Counter-clockwise = left-turning
- Foranothermeasurementpushthebutton“SELECT”once
briey.Todeactivatethefunction,keepthe“SELECT”but-
ton pushed for at least 2 seconds.
- Remove the measuring lines from the object to be meas-
ured after completion of the measurement and switch off the DMM.
 Thefunctionbuttons“RANGE”,“MAXMIN”,“REL”and“PEAK”aredeactivatedinthismeasuringfunction
and cannot be selected.
