RPV (read pressure value)
Reading a pressure value for a measurement channel.
Example: RPV[a]<CR>
Response: b[,][TAB]x.xxxxE±xx
SSC
Set Sensor Control
Set type of sensor control for a measurement channel.
RSP
Read Setpoint
Read switching thresholds for a channel.
SSP
Set Setpoint
Set switching thresholds for a channel.
Note:
All changes to values are only permanently saved to the EEPROM after having issued the write
command SAC. For this reason after having set all values, save the current configuration
through the SAC write command before restarting the instrument.
