Displayed results:
Uc ........ contact voltage
Rl ......... fault loop resistance
5.5.2 Trip-out time (RCDt)
Trip-out time measurement verifies the sensitivity of the RCD at different residual currents.
Trip-out time measurement procedure
 Select the RCD function using the function selector keys.
 Set sub-function to RCDt using UP / DOWN keys.
 Set test parameters (if necessary).
 Connect test cable to the instrument.
 Connect test leads to the item to be tested (see Figure 5.20).
 Press the TEST key to perform the measurement.
 Store the result by pressing the MEM key (optional).
