4.3.3.9 Extended Meters
When Extended Meters is on, it can be switched to display I-maximum or MD Voltage by
press ENTER key during testing. When Extended Meters is off, the switch function is disable.
I-maximum function will measure and display the max. current for each test. MD Voltage
function will measure and display the voltage between two terminal of MD.
4.3.3.10 AC / DC Display Selection (Option)
Pressed AC/DC softkey, user can select the leakage current value to be AC+DC, AC or DC.
4.3.3.11 Ranging Mode Setting
When Ranging Mode is Auto, system will auto select the suitable current range. At the mode,
Dwell time can't be shorter than Ranging judgment time. If Dwell time is shorter than
Ranging judgment time, the Dwell time will be forced to be changed to same as Ranging
judgment time.
When Ranging Mode is Manual, system will judge the current range depends on Leakage-HI
setting.
4.3.3.12 Continuous Setting
The softkey can set the output power status for step link. When Continuous is on, and both two
link step are at the same line status, the power will continue output during two steps link. If
Continuous is on but two link step are not at the same line status, the power will stop output
first after first step test is finished.
When Continuous is OFF, whenever two link steps are at the same line status or not, it will
stop output first after the step test is finished. Then it will restart to process next step.
PLC Control (Option for Opt. 752)
Please use the up and down arrow keys or the ENTER key and scroll the highlighted area to
the PLC Control parameter. The display will appear as follows:
Please press PLC Control softkey to select the power mode. If option AC power source to be
the DUT input power, there are 7 memories M1 to M7 for selected. If option 1931 series, there
are three voltage rate 1.0, 1.06, and 1.1 times for selected. If option 1931S series, there are six
voltage rate 0.8, 0.85, 0.9, 1.0, 1.06, and 1.1 times for selected.
