Scientech S200 Vector - Manual (Page 33)

ATTEN <dec num> Sets the attenuation factor to apply in the calculation of energy or power. In the D200
this command applies to the channel selected by the SEL command.
D200P, D200PC, D200C SPECIFIC COMMANDS
DSP A | B | A/B | B/A This command tells the dual channel indicator what to display on the front panel. An
argument of A means display readings from channel A in the front panel. A value of B/A tells it to display the
ratio of the reading on channel B to the reading on channel A on the front panel.
DSP? This query returns either A, B, A/B, or B/A, to indicate what is currently displayed on the front panel.
SEL A | B | A/B | B/A | AB The SEL command is the channel selector for the remote interface. It tells the
Indicator what readings to transmit out the remote interface. An argument of A means transmit readings from
channel A. An argument of AB tells it to transmit readings from both channels. Merely using the SEL
command does not guarantee that readings will be transmitted. The user must then issue a specific request
to transmit readings, such as RPT?, SND?, or COL?. The SEL command has the further effect of
specifying to indicator to which channel it should apply the CAL, CAL?, ATTEN, ATTEN?, RANGE, and
RANGE? commands. If the most recent SEL command involved both channels, then the six commands
above become invalid until the user issues a SEL A or SEL B command.
SEL? This query returns A, B, A/B, B/A, or AB to indicate which channels will be output in the event of a
RPT?, SND?, or COL? query, which channel will be collected in the event of a COL command, and to what
channel the CAL, ATTEN, and RANGE commands apply.
LOG ON | OFF This command turns on or off the logarithmic display of the ratio of channel A to channel B
or the ratio of channel B to channel A. This command turns on or off a flag that has effect only when DSP or
SEL has been used to select a ratio for display or output.
TRIG A | B Tells the D200P which channel to trigger from.
TRIG? Returns A or B depending upon the current trigger channel.
AD30 SPECIFIC COMMANDS
ZERO This command sets the zero point in watts mode to the ambient reading from the calorimeter.
CAL? Returns the time constant in seconds of the calorimeter.
CAL <dec num> Sets the time constant constant in seconds of the calorimeter.
