RCD Trip Current
 Warning
To prevent possible electrical shock, fire, or personal injury, do
not touch the L or N input jacks while performing the following
tests. These input jacks have line voltage on them during the
test.
To test the RCD trip current accuracy, perform the following procedure for each step in Table 7.
1. Connect the UUT’s L, PE and N to the 5320A as shown in Figure 9.
2. Turn the UUT rotary switch to the ∆T function.
3. On the UUT, set <, , and  to the values shown in Table 7.
4. ON the 5320A, press  and using the MODE key and Cursor key, select
Trip Current.
5. Press the 5320A softkey to select Trip I. Using the cursor keys, modify the Trip I to the
same value as the UUT RCD nominal trip current (< setting).
6. Put the 5320A in OPER and wait to settle.
7. Press .
8. Compare the measured RCD trip current (or Maximum value Parameter) on the 5320A
display to the Current Accuracy limits in Table 7.
If the 5320A did not trip, press the Clear softkey on the 5320A to clear the maximum
value.
