3.1.7 PRES ON/OFF Key and LED Monitor
Depressing PRES Key will be ON, further depressing will be OFF, further depressing
will be ON again and so on. ON means Preset ON, e.g., to preset condition display to
ON. OFF means preset OFF, e.g., the condition is not preset and shall be the actual
condition of the voltage and current of the load.
Under Preset OFF condition, the upper 4 1/2 digit monitor displays the voltage input
to electronic load while the lower 4 1/2 digit monitor displays the current flowing into
electronic load with the unit as
〝
Vrms
〞
&
〝
Arms
〞
respectively and the unit indicator
will come on also.
Under Preset ON condition, PRES LED monitor is ON, both upper and lower 4 1/2
digit monitors will have different displays with the change of working mode as shown
below:
3.1.7.1
C.C.Mode:
The setting value of Level A / B load current can be displayed on the lower
4 1/2 digit monitor with the unit as
〝
Arms
〞
, LED indicator will be ON.
3.1.7.2 Linear C.C. Mode:
The setting value of Level A / B load current can be displayed on the lower
4 1/2 digit monitor with the unit as
〝
Arms
〞
, LED indicator will be ON.
3.1.7.3
C.R.Mode:
The setting value of Level A/B load resistance can be displayed on the
lower 4 1/2 digit monitor with the unit as
〝
Ω
〞
, LED indicator will be ON.
