To select an appropriate IR current range, please calculate the current by
test voltage and UUT’s insulation impedance, and then select the proper
current range. It will show UUUUU if the IR display exceeds 60GΩ.
CHANNELS : It sets the high voltage channel for output. Select Function Key
[DEFAULT] means to use the “DEF. CHANNELS” settings in “TEST
CONTROL.” Select Function Key [SETUP] means to reset the high
voltage channel for output.
SCANNER : It sets the output mode of A190201/A190202 SCANNER. It can select
[ PS ], [ PC ], [ SC ], [ P+SC ] and [ PS+C ]. It is only valid
when the LINK SETUP in the SYSTEM of 19020/19020-4 is set to
SCANNER.
Please follow the model to set the output channel, for instance, the 19020
can set the output channel to CH1~CH10 while the 19020-4 can only set
the channel to CH1~CH4. The message line on the test screen will show
“Module Fail” if set otherwise and the test is unable to start.

OPEN : It sets the OPEN condition for test result judgment. (Compare it with the
test reading and the read standard capacitance [Cs].)
SHORT : It sets the SHORT condition for test result judgment. (Compare it with the
test reading and the read standard capacitance [Cs].)
CHANNELS : It sets the high voltage channel for output. Select Function Key
[DEFAULT] means to use the “DEF. CHANNELS” settings in “TEST
CONTROL.” Select Function Key [SETUP] means to reset the high
voltage channel for output.
SCANNER : It sets the output mode of A190201/A190202 SCANNER. It can select
[ PS ], [ PC ], [ SC ], [ P+SC ] and [ PS+C ]. It is only valid
when the LINK SETUP in the SYSTEM of 19020/19020-4 is set to
SCANNER.
1. Before conducting the test or testing the new capacitance UUT or
replacing the capacitance UUT in OSC Mode, the action of reading
standard capacitance (GET Cs) has to be done first.
2. Before reading standard capacitance (GET Cs), press Function Key
