Calibration Information

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:
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
3. Press the UUT GFCI pushbutton for one second. The UUT DC + and DC – LEDs

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
2. Move the UUT COM lead to C-phase. The rotary field direction indicator arrow
