SERIES EL 062011

3.13.3.3 PROTECTION SUBSYSTEM

This subsystem establishes limits for voltage, current and power.

3.13.3.4 [SOURCE:]MEASURE SUBSYSTEM

This query subsystem returns the voltage, current and power measured at the LOAD terminals.

3.13.3.5 [SOURCE:]INPUT, [SOURCE:]OUTPUT SUBSYSTEMS

This subsystem controls whether the UUT is engaged (on) or disengaged (off) from the load.

3.13.3.6 [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.

3.13.3.7 [SOURCE:]RESISTANCE, [SOURCE:]CONDUCTANCE SUBSYSTEMS

These subsystems set the mode and establish setpoints for each mode.

3.13.3.8 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.

3.13.3.9 SYSTEM SUBSYSTEM

This subsystem controls various system functions.

PROTECTION COMMANDS (Terminate command with ? to display the protection setting for that mode.
Exceeding these user-defined protection levels disengages the UUT and displays fault indication (see
PAR. 3.3.1.)

CURRent:PROTection

Set maximum Current level in Amperes

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

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.
