STB6684/A Operation Manual
2) Use above softkeys to set the measurement range.

3.1.8 Rin_L

STB6684/A employs 10kΩ low input impedance when the current range is larger than 10nA;
and 1MΩ internal impedance when the current range is less than 10nA, shown as follows:
Range 1 :10OuA – 1mA ; input internal impedance 10 kΩ
Range 2 :10uA – 100uA ; input internal impedance 10 kΩ
Range 3 :1uA – 10uA ;
Range 4 :100nA – 1uA ;
Range 5 :10nA – 100nA ; input internal impedance 10 kΩ
Range 6 :1nA – 10nA ;
Range 7 :10pA – 1nA ;

3.1.9 TRIG

STB6684/A has 3 trigger modes: MAN, EXT, BUS.
In MAN mode, STB6684/A makes a measurement by each press of [TEST].
In EXT mode, STB6684/A makes a measurement when the HANDLER interface receives
a positive impulse trigger signal.
In BUS mode, STB6684/A makes a measurement when the IEEE488 interface receives
a "TRIGGER" command. Bus mode can not be set on the front panel of the instrument.
————————————————————————————————————
NOTE: If a trigger signal is received by STB6684 in the phase of test, it will be
ignored. Therefore, trigger signals can be sent to STB6684 when the test ends.
When the optional HANDLER interface is used to trigger STB6684, the trigger mode
should be set to EXT mode.
