Caution
● Do not input voltage higher than 440V or 440Vrms. It may be possible to display the
voltage value, but it may pose hazard to the Tester.
● To avoid electric shock, please take extreme caution when working with high voltage.
● Remove the test leads away from tested circuits and disconnect them from the input
terminals of the Tester after completing the measurements.
● Do not measure with the battery cover opened.
To Detect Phase Sequence:
(1) Turn the rotary switch to Phase Rotation position.
(2) Insert three connectors of three test leads into input terminals of the Tester(red to red,
green to green, black to black).
(3) Then connect three test leads into three-phase AC system(black to L1, green to L2,
red to L3, refer to Figure 6 for details), after that, the Tester will indicate the phase
sequence and open phase result on LCD.
