In order for the indicator to show current values, the cur-
rent transformers connected to the indicator must first be
programmed.
The DMA-3 CT indicator is adapted for use with the following
current transformers with 5A secondary and primary current:
20, 25, 30, 40, 50, 70, 75, 80, 100, 120, 125, 150, 160, 200, 250,
300, 400, 500, 600, 700, 750, 800, 900, 1000 A.
