• This -852B phase indicator is design to check the of open phase and phase sequence thru the designated LEDs and an audible buzzer sound simultaneously. This handheld instrument correctly identify the rotary field of a three phase system ensuring that correct phase sequencing is achieved.
• Testing is as easy as connecting the included well insulated clips of the unit to the three phase circuit under test and the unit will indicate the of open phase & phase sequence thru the LEDs and buzzer.
• Continuous Use Time: ≤60 minutes at 200V AC; ≤4 minutes at 600V AC ;Maximum Withstand Voltage: 2000V/min (impulse voltage 4000V)
• It is not allowed to be used in outdoor and humid environment when it is raining to avoid unsafe accidents.
• Do not expose the instrument to water or other corrosive liquids, and do not place it in an environment with direct sunlight or high temperature and relative humidity, so as not to affect its test performance.
