Figure 7-17. RCD Trip Time and Trip Current Calibration
Calibrating Using 1 X I Multiplier
In the 1 x I Multiplier mode, the Calibrator acts like a circuit breaker with a set nominal
trip current and trip time. To perform a calibration of RCD time:
1. Using Figure 7-17, connect the UUT to the Calibrator’s L, PE, and N terminals.
2. Press R.
3. If RCD Trip Time does not already appear in the Output area of the display, press
the Mode softkey. Then, using the cursor keys or rotary knob, highlight Trip Time
and select it by pressing the Select softkey or pushing in on the rotary knob.
4. On the UUT, set the following parameters:
I multiplier set to 1xI
Nominal trip current (ITRIP) set.
S or G type RCD NOT set
AC or DC sensitive testing NOT set
Phase polarity NOT set
Maximum touch voltage NOT set
Note
Not all parameters can be accessed on the UUT. However, nominal trip
current must always be set or known.
5. On the Calibrator, make the following 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 1xI
I level coefficient. Default set to 90%.
Series resistance of touch voltage will be simultaneously tested. The default
series resistance is set to the minimum value.
