3. Push the Mode softkey. Then, use the cursor keys or rotary knob to highlight
PAT and select it by pushing the Select softkey or pushing in the rotary knob.
4. On the DUT, set these parameters:
I multiplier set to 1.4XI, 2xI, or 5xI
Nominal trip current (ITRIP) set.
5. On the Product, make these settings:
Nominal trip time in ms
Nominal trip current (ITRIP) set to the same value the RCD is set to.
I multiplier coefficient set to 1.4xI, 2xI, or 5xI, same as that on the DUT.
I level coefficient. Default set to 90 %.
6. Push .
7. On the DUT, push Start.
The Product measures the current. After the nominal trip current is reached,
the Product starts a timer, and then disconnects the output terminals when
the nominal trip time has elapsed.
8. Compare the nominal trip time on the Product display with the trip time
displayed on the DUT. The Product shows actual trip current sourced by
DUT.
