SERIES EL 070312
3.13.3.2 PROTECTION SUBSYSTEM
This subsystem establishes limits for voltage, current and power.
3.13.3.3 [SOURCE:]MEASURE SUBSYSTEM
This query subsystem returns the voltage, current and power measured at the LOAD terminals.
3.13.3.4 [SOURCE:]INPUT, [SOURCE:]OUTPUT SUBSYSTEMS
This subsystem controls whether the UUT is engaged (on) or disengaged (off) from the load.
3.13.3.5 [SOURCE:]VOLTAGE, [SOURCE:]CURRENT, [SOURCE:]POWER SUBSYSTEMS
These subsystems set the mode and establish setpoints for each mode. Also establish protec-
tion limits and the range of the front panel display (VOLTS, AMPS or KW, respectively) for each
mode.
3.13.3.6 [SOURCE:]RESISTANCE, [SOURCE:]CONDUCTANCE SUBSYSTEMS
These subsystems set the mode and establish setpoints for each mode.
3.13.3.7 STATUS SUBSYSTEM
This subsystem programs the Series EL status register. The electronic load has two groups of
status registers: Operation and Questionable. Each group consists of three registers: Condition,
Enable, and Event.
VOLTage:PROTection:OVEr Set maximum Voltage level in volts
VOLTage:PROTection:UNDer Set minimum Voltage level in volts
POWer:PROTection Set maximum load Power in watts
STATUS CLEAR COMMANDS. Trip error prevents INPut 1 or OUTPut 1 from engaging the load. See STA-
Tus:QUEStionable register for error definitions (see PAR. 3.13.7.3)
CURRent:PROTection:STATe 0 Clear overcurrent error
POWer:PROTection:STATe 0 Clear over power error
VOLTage:PROTection:UNDer:STATe Clear undervoltage error
VOLTage:PROTection:OVEr:STATe Clear overvoltage error
VOLTMETER RANGE COMMANDS. Terminate command with ? to display the range setting. The voltme-
ter range is determined by the lower of: the range setting below and the lowest range that includes the
current VOLT setting.
SYSTem:RANGe:VOLTage 100V Set Voltage measurement range 0 – 100V
SYSTem:RANGe:VOLTage 200V Set Voltage measurement range 0 – 200V
SYSTem:RANGe:VOLTage 400V Set Voltage measurement range 0 – 400V
SYSTem:RANGe:VOLTage 800V Set Voltage measurement range 0 – 800V
= Numeric Values with or without a decimal point. Examples: 0.0156, 15.6, 156 or 1.56E+3 (scientific
notation: digits with decimal point and exponent).
NOTE: If commands that expect a boolean are entered without an argument, the argument is interpreted as 0.
