Note
：
1. If REVERSE parameter is ON or AUTO, probe will not have the
Ground To Neutral
and
AUTO
selection items.
2. It belongs to the application of Standard IEC 60335-1 Fig.2 that both the switch SH and SL are on the A
position.
When the Probe is set to AUTO, the system will measure the leakage current that probe switch
is on A and B position. Whichever is larger, the LCD always displays the larger value.
Leakage Measuring
1.
Ground To Line (G-L)
：
SH, SL and Probe Switch are on A position.
2.
Ground To Neutral (G-N)
：
SH and SL are on A position
，
Probe Switch is on B position.
3.
Probe-HI To Line
(PH-L)
：
SH is on B position, SL and Probe Switch are on A position.
