Figure 2. Load Current/GFCI Current Test
GFCI Trip Test
To test the GFCI Trip current accuracy, set up the UUT and equipment as shown in Figure 2, and
complete the following procedure:
Note
When you press the GFCI pushbutton, the resulting test will last for up to
seven seconds.
1. Set the DMM to the mA ac function.
2. Apply 100 V, 60 Hz from the Source. The DMM reading should light the 12 – 48 V
LEDs and Hazard symbol.
3. Press the UUT GFCI pushbutton for one second. The UUT DC + and DC – LEDs
should alternately switch on and off while the beeper sounds. The DMM reading
should be between 6 and 9 mA ac during the test.
Rotary Field Test (T+ PRO)
To test the rotary field direction indicator, complete the following procedure:
1. Connect the UUT to a 60 Hz, three-phase source of > 120 V, with the UUT red lead
to A-phase and the UUT COM lead to B-phase. The UUT’s rotary field direction
indicator arrow should point to the right.
2. Move the UUT COM lead to C-phase. The rotary field direction indicator arrow
should point to the left.
