MD 126 Detector
Phase Sequence Test Mode
Place the tip of the tester close to the L1 phase wire.
The tester will beep once. The green and yellow LED
will rapidly alternately flash to indicate the
measurement of the first phase in sequence is
complete.
Move the tip of the tester close to the L2 phase wire.
When the measurement is complete there will be two
possible results:
1. The tester beeps and green LED turns on for
about 5 seconds to indicate a correct phase
sequence (L2 is ahead of L1 by 120 degrees).
2. The tester beeps and the yellow LED turns on
about for 5 seconds to indicate an incorrect phase
sequence (L2 is lagging after L1 by 120 degrees).
Test L1 and L3, L2 and L3 in the same way.
Note: To improve test accuracy, do not place the tester
tip in the middle between two phase lines.
Note: If the phase sequence test is not completed
within 1 minute, the red LED will turn on, the green and
yellow LED will flash alternately, and the tester will
beep 5 times to indicate that phase sequence test is
invalid. The test will reset to the phase sequence test
mode. L1 must be measured again.
Low Battery Indication
