Multifunction Electrical Tester Calibrator
Use the RCD Test Functions
59
Note
The incremental step level for RCD Trip current from a DUT
depends on the manufacturer’s design and lies between 2 % and
10 % per step. Full wave or pulse trip current can be used
depending on the DUT.
To perform an RCD Calibration:
1. Push .
2. If RCD Trip Current is not already displayed, push the Mode softkey.
3. Using the cursor keys or rotary knob, highlight the Trip Current selection and
either push the Select softkey or push in the rotary knob.
The last nominal trip current and the series resistance for touch voltage
simulation settings are shown in the PARAMETERS area of the display. If the
nominal trip current setting needs to be changed, see To Change the
Nominal Trip Current section below. If the resistance setting needs to be
changed, see To Change the Touch Voltage section below.
XWWarning
To avoid electric shock, ensure the Product is in standby while
making connections to the L and N connectors. Lethal voltages
are present on the L and N connectors during RCD Trip Current
calibration.
4. Referring to the terminals part of the display, connect the DUT to the Product.
5. Push to start the calibration process.
6. Push Start on the DUT.
When the level of test current flowing from the DUT reaches the set nominal trip
current value, the Product starts to measure current amplitude. The measuring
process lasts for several power line cycles. The Product simulates tripping of a
breaker by disconnecting the output connectors and displays the measured trip
current.
