SERIES EL 063010
B.111 SYSTem:RANGe:CURRent COMMAND
SYST:RANG:CURR
Syntax:
Short Form: SYST:RANG:CURR
Where
Description: Establishes range for remote interface current readback and front panel AMPS display. LOW
changes the current range to 1/10 of full scale. If the unit is 200A at full scale, entering
SYST:RANG:LO, changes the ammeter range to 0 - 20A full scale.
B.112 SYSTem:RANGe:CURRent? QUERY
SYST:RANG:CURR?
Syntax:
Short Form: SYST:RANG:CURR? Long Form: SYSTem:RANGe:CURRent?
Returns:
Description: Indicates the range for remote interface current readback and front panel AMPS display.
B.113 SYSTem:RANGe:POWer COMMAND
SYST:RANG:POW
Syntax:
Short Form: SYST:RANG:POW
Where
Description: Selects one of two power ranges, low (default) or high for remote interface power readback
and KW meter on front panel. The power ranges are a function of the full scale ammeter range.
For example, for a 5 kW load (600A, 50V), the instrument inherently has a 600A full scale range. So
at, for example, the 100V voltmeter range, the dynamic range of power measurement is: (0 - 100V)
x 600A = 0 - 60,000 Watts, much higher than needed. Therefore, when the voltage is high and the
current is low, SYST:RANG:POW LOW restricts the ammeter to 1/10th of full scale and thus, in this
example, limits the maximum power reading to 6,000 Watts.
B.114 SYSTem:RANGe:POWer? QUERY
SYST:RANG:POW?
Syntax:
Short Form: SYST:RANG:POW?
Long Form: SYSTem:RANGe:POWer?
Returns:
Description: Indicates one of two power ranges, low (1/10 full scale) or high for remote interface power
readback and KW meter on front panel.
B.115 SYSTem:RANGe:VOLTage COMMAND
SYST:RANG:VOLT
Syntax:
Short Form: SYST:RANG:VOLT
where
Description: Establishes full scale voltage range of remote interface voltage readback and VOLTS display
on front panel. This setting is saved in non-volatile memory and is retained for subsequent power-up.
B.116 SYSTem:RANGe:VOLTage? QUERY
SYST:RANG:VOLT?
Syntax:
Short Form: SYST:RANG:VOLT? Long Form: SYSTem:RANGe:VOLTage?
Returns:
Description: Indicates full scale voltage range for remote interface voltage readback and VOLTS display on
front panel.
B.117 SYSTem:REPly COMMAND
SYST:REP
Syntax:
Short Form: SYST:REP
Long Form: SYSTem:REPly
Where
Description: Turns reporting of error messages on (1) or off (0). Turns on/off reporting of error messages gener-
ated when SCPI parser analyses SCPI commands. When set to 0, If command is understood, the EL
load provides the normal or expected response. When set to 1, if command is understood, the EL load
provides the normal or expected response, followed by OK. If the command is not understood, the EL
Load responds with “??” and the appropriate error message is added to the error queue. (see PAR.
B.102 for details).
