The 887 PR is a 3 Phase Presence and Rotation Indicator. It does not need any batteries as it delivers its power from the system under test. It can be utilized on a 3 Phase Powered System without having to worry about damage to the tester or the system.
Once connected to a 3 phase power system, it indicates the Phase presence by showing its corresponding LCD symbol. It displays the rotation (closkwise or counter-clockwise) on the LCD.
This instrument represents the quickest and easiest way for verifying the presence and rotation of a 3 Phase System.
You can, before connecting supply to load, and from the supply side quickly and easily verify the presence of the three Phases on a 3 Phase Power System and confirm the phase rotation on a Powered 3 Phase System.
3 Phase Presence Indication circuit: This circuit uses the LCD to indicate if a phase is present. These LCD indicators will light up when the voltage across any two phases are more than 40Vac. This product does not require any batteries as it takes it's power from the circuit under test.
