⑧ Short Circuit Operation:
The first line shows measured voltage and current levels. The second line shows set level in
short circuit (Take 3721A as an example, short circuit test current in CCL is 4.4A; short circuit
test current in CCH is 44A; short circuit test voltage in CV is 0V; short circuit test resistance in
CRL is 0.018Ω; short circuit test resistance in CRM is 1.8Ω; short circuit test resistance in CRH
is 18Ω; short circuit test power in CPV is 420W; short circuit test power in CPC is 0W), short
circuit operation mode (sCCL，sCCH，sCV，sCRL，sCRM，sCRH，sCPC，sCPV； “s” indicates
short circuit test), and input status of the load (ON, OFF).
⑨ Display Actual Power:
Pressing
and key can switch the display of load status and actual power. On the
display screen of actual power, the first line shows actual voltage and current; the second line
shows set level and actual power level.
⑩ Protection Status
If the protection function is active, LCD will display corresponding protection status. For
example: the display of reverse voltage protection status is shown as below:
Protection status includes overcurrent (OC), overvoltage (OV), overpower (OP), over temperature
(OT), load protection (PT), and reverse voltage (RV).
1.8 Remote Programming
The commands are sent to electronic load via remote interface (RS232, GPIB, USB), and will be
executed after decoding by the processor. If there is any error occurs to the command, the processor
can detect the wrong command and error type, and it can maintain the status register as well.
