INPut
{A | B | C | D}
Default: Auto
BRANge
{Auto | 1.0MA | 100UA | 10UA}
Sets or queries the resistance bridge range. This is a range-hold function.
Normally, this is set to auto so that the instrument will autorange excitation.
For special applications, the resistance bridge may be set to a specific
excitation range.
INPut
{A | B | C | D}
:SENSor <ix>
Sets or queries the sensor index number. <ix>, is taken from Appendix A
INPut
{A | B | C | D}
:SENSPwr?
Queries the sensor power dissipation in Watts. Response is in scientific
notation.
INPut
{A | B | C | D}
:BRUNlock?
Queries the bridge unlock indicator. Returns a space character if the bridge is
locked or an asterisk (*) character if the bridge is unlocked.
If the bridge is unlocked, it is still searching for a balance point. The sensor
reading will be correct, but the excitation current and power dissipation will be
incorrect.
INPut
{A | B | C | D}
:ALARm?
Queries the alarm status of the specified input channel. Status is a two
character string where:
--
indicates that no alarms are asserted
SF
indicates a Sensor Fault condition.
HI
indicates a high temperature alarm
LO
indicates a low temperature alarm.
The user selectable display time constant filter is applied to input channel
temperature data before alarm conditions are tested.
INPut
{A | B | C | D}
:ALARm:HIGHest <setpt>
Sets or queries the temperature setting of the high temperature alarm for the
specified input channel. When this temperature is exceeded an enabled high
temperature alarm condition is asserted.
INPut
{A | B | C | D}
:ALARm:LOWEst <setpt>
Sets or queries the temperature setting of the low temperature alarm for the
specified input channel. When the input channel temperature is below this, an
enabled low temperature alarm condition is asserted.
Temperature is assumed to be in the display units of the selected input
channel.
INPut
{A | B | C | D}
:ALARm:DEAdband <setpt>
Sets or queries the dead-band setting. Dead-band is assumed to be in the
display units of the selected input channel.
INPut
{A | B | C | D}
:ALARm:HIENa
{
YES
|
NO
}
Sets or queries the high temperature alarm enable for the specified input
channel. An alarm must be enabled before it can be asserted.
