Step 3
•
Select
Multiplier
of Nominal differential current as follows:
•
Press the
SELECT
key after setting Nominal differential current, last set
Multiplier starts to blink.
•
Select appropriate value by using the
↑↑↑↑
and
↓↓↓↓
keys. The following values are
available to be selected: ×1/2, ×1, ×2, ×5. The value × 5 is not available, if
Nominal current I
∆
N = 1000 mA.
Step 4
•
Select Type of tested RCD as follows:
•
Press the
SELECT
key after setting the Multiplier, last set type starts to blink.
•
Select appropriate type using the
↑↑↑↑
and
↓↓↓↓

according to the figure 21. (Plug commander) or figure 22. (Universal test cable).
Step 6
Press the
START
key and release it. Measurement will be carried out and result
displayed afterwards (Trip-out time at set differential current).
Double click to
START
key will change positive start polarity of test current to negative
one; see the figure below.

•
Check Contact Voltage at set Nominal differential current (Standard RCD type)
or at double Nominal differential current (Selective RCD type) and set Limit
Contact voltage by using the
DISPLAY
key.
•
Store displayed results for documentation purpose; see instructions how to store
it in chapter 4.1. Storing of test results.
