Unless the REVERSE parameter is “ON”, the OFFSET setting always and indicates the value
that S2 is on the A position(OFF). When the REVERSE parameter is “AUTO”, system will
display the offset value of A position and save the value of B position to RAM to further
calculate the leakage of A and B position then indicates the max. one. The calculation of
leakage is:
Leakage Current = READING
2
- OFFSET
2
The LCD always displays and indicates the max leakage current of test result. For an
example
：
If the setting of REVERSE and OFFSET parameters are “AUTO”, the Offset and leakage
value are separately 5.0uA and 145.0uA for B position (ON) and the Offset and leakage value
are separately 8.0uA and 140.0u for A position (OFF) after “TEST” was pressed.
For A position (REVERSE=OFF)
：
Leakage Current = 140.0
2
- 8.0
2
=139.8uA
For B position (REVERSE=ON)
：
Leakage Current = 145.0
2
- 5.0
2
=144.9uA
So the LCD will indicates the Leakage Current is 144.9uA and Offset is 8.0uA.
4.3.3.5 Line Configuration (NEUTRAL; REVERSE; GROUND)
Please use the up and down arrow keys or the ENTER key and scroll the highlighted area to
the
NEUTRAL
,
REVERSE
, or
GROUND
parameter. The display will appear as follows:
The LINE configuration is determined by the switches S1, S2 and S3 (refer to Figure 2) and is
set using the corresponding Line Configuration Soft keys. S1 relay is represented as
NEUTRAL and is controlled by the Neutral soft key. S2 relay is represented as REVERSE
and is controlled by the Reverse soft key. S3 relay is represented as GROUND and is
controlled by the Ground soft key.
