0.5 – This setting is used for Installation testers that test non-tripping RCDs. When this
value is set, the Calibrator measures UUT trip current for 5 seconds and then disconnects
the output terminals. If the UUT current exceeds the set nominal trip current or is greater
than 4000 mA, the Calibrator disconnects the output connectors and displays a “Trip
current too high” error message.
1 – This setting is the most common for Installation testers. Depending on the I level
parameter, the Calibrator may or may not ignore any pretest pulses generated by the UUT
which are below the value determined by I level and nominal trip current settings. Pretest
pulses are ignored if their level is below the pretest I level value. If the pretest pulses are
higher than the I level parameter, the Calibrator reads them as real trip current pulses.
1.4 and 2 – These settings are used for testing UUTs that measure current overloading.
The Calibrator’s and UUT’s current multiplier should be set to the same value when
calibrating using this setting. These settings multiply the nominal trip current setting by
1.4 or 2 and uses it as the trip point. If the trip current exceeds 300% of the nominal
current setting or 3000 mA, the output terminals are disconnected and a “Trip current too
high” error message displayed. The maximum nominal trip current that can be used with
this setting is 1500 mA.
5 – This setting multiplies the nominal trip current by 5 and uses that value as the trip
current value. If the trip current exceeds 750 % of the nominal trip current setting or 3000
mA, the output terminals are disconnected and a “Trip current too high” error message is
displayed. The maximum nominal trip current that can be used with this setting is 600
mA.
Note
Multiplier values of 2 and 5 are for testing of fast tripping RCDs.
To change the current level detection setting:
1. Press the Setup softkey.
2. Using the cursor keys or rotary knob, highlight the RCD selection and either press
the Select softkey or press in on the rotary knob
3. Using the cursor keys or rotary knob, highlight I level and either press the Select
softkey or press in on the rotary knob.
4. Using the cursor keys or rotary knob, highlight the desired current level (5, 30, 60,
75, 90, 100, and 120) and either press the Select softkey or press in on the rotary
knob.
The I level parameter allows the Calibrator to ignore pretest pulses generated by
many UUTs. Pretest pulses can be a high as 50 % of the nominal trip current value.
This parameter is also used for testing UUTs that generate trip currents less than the
nominal trip current. The recommended setting is 90 % and is set as the default value
for the current level.
Note
The Calibrator independently evaluates trip current on each half-wave of
the measured trip current.
Installation testers can be set for Standard or Sensitive RCDs. Standard RCDs have a trip
time range between 10 ms and 500 ms. Sensitive RCDs range between 40 ms and 5
seconds. Although the Calibrator cannot detect which of these two settings the UUT is
