Appropriate Usage
The instrument may only be used under those condi-
tions and for those purposes for which it was con-
ceived. For this reason, in particular the safety refer-

4.0 Control Elements
1. Test lead connection sockets
2. Lamps for indication of the individual phases L1, L2,
L3
3. LED to display clockwise rotary direction (right-
hand rotation)
4. LED to display counter-clockwise rotary direction
(left-hand rotation)
5. LED to display operation status
6. Button to switch on the instrument
5.0 Determination of the Rotary Field
Direction
Within a three-phase system the sequence of the three
phases connected determine the rotary direction of
the motor connected. The correct phase sequence L1,
L2, L3 results in a clockwise rotation.
" Connect cables and test probes respecting the cor-
rect sequence to the test instrument
" (yellow to L1 / green to L2 / red to L3)
" Connect the test probes with the three mains phas-
es.
