Maintenance, Cleaning, Technical Data
6.0 Determination of the Rotary Field Direction
Within a three-phase system the sequence of the three phases determine the
rotary direction of a motor connected.
The correct phase sequence L1, L2, L3 results in a clockwise rotation.
• Connect test probes respecting the correct sequence to the test instrument
• Connect the test probes with the three mains phases
• If the LED "R" is illuminated, a clockwise rotary field is present. If the LED
"L" is illuminated a counter-clockwise rotary field is present.
7.0 Maintenance
When using the instrument in compliance with the instruction manual, no
special maintenance is required.
8.0 Cleaning
If the instrument is dirty after daily usage, it is advised to clean it by using
a humid cloth and a mild household detergent. Prior to cleaning, ensure
that instrument is disconnected from external voltage supply and any other
instruments connected. Never use acid detergents or resolvent for cleaning.
After cleaning, do not use the HDT Phase Rotation Indicator for a period of
approx. 2h.
