B.92 SYSTem:RANGe:CURRent COMMAND

SYST:RANG:CURR

Syntax:

Short Form: SYST:RANG:CURR Long Form: SYSTem:RANGe:CURRent
Where = HIGH (HIGH = factory default) or LOW

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.93 SYSTem:RANGe:CURRent? QUERY

SYST:RANG:CURR?

Syntax:

Short Form: SYST:RANG:CURR? Long Form: SYSTem:RANGe:CURRent?
Returns: = HIGH or LOW

Description: Indicates the range for remote interface current readback and front panel AMPS display.

B.94 SYSTem:RANGe:POWer COMMAND

SYST:RANG:POW

Syntax:

Short Form: SYST:RANG:POW Long Form: SYSTem:RANGe:POWer
Where = HIGH or LOW (LOW = factory default)

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.95 SYSTem:RANGe:POWer? QUERY

SYST:RANG:POW?

Syntax:

Short Form: SYST:RANG:POW?

Long Form: SYSTem:RANGe:POWer?

Returns: = HIGH or LOW (LOW = factory default)

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.96 SYSTem:RANGe:VOLTage COMMAND

SYST:RANG:VOLT

Syntax:

Short Form: SYST:RANG:VOLT Long Form: SYSTem:RANGe:VOLTage
where = 100V, 200V, 400V or 800V

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.97 SYSTem:RANGe:VOLTage? QUERY

SYST:RANG:VOLT?

Syntax:

Short Form: SYST:RANG:VOLT? Long Form: SYSTem:RANGe:VOLTage?
Returns: = 100V, 200V, 400V or 800V

Description: Indicates full scale voltage range for remote interface voltage readback and VOLTS display on

front panel.

B.98 SYSTem:REPLY COMMAND

SYST:REPLY

Syntax:

Short Form: SYST:REPLY Long Form: SYSTem:REPLY
Where = 0 or OFF = replies off or 1 (or ON) = replies ON

Description: Turns reporting of error messages on (1) or off (0). Turns on/off reporting of error messages gen-

erated 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.83 for details).
