• Validation Allowance: Sets the tolerance (±%) for validation
measurements when Val 1 Concentration or Val 2 Concentration is set
to a value greater than 0.
• Validation Wait Time: Sets the amount of time (in seconds) for the
validation gas to purge the system at the beginning of the validation.
• Val Perm Constant Kp: Sets the system constant for the perm
tube.
• Val Perm Rate Rp: Sets the calibrated permeation rate for the perm
tube.
• Val Purge Period: Sets the number of seconds upon validation
initiation that a differential analyzer will purge the system with
validation gas before starting a dry cycle.
• Val Start Time: Sets the hour of the day for the daily autovalidation
to begin.
• Val Time: Time of last validation.
• Wet Pressure (mb): Current measured (live) wet pressure reading
of the gas sample in millibar (mb).
• Wet Temp (C): Current measured (live) temperature of the gas
sample in degrees Celsius.
• Zero Val Tolerance: Sets the maximum acceptable reading (in
ppmv) when validating with zero gas (Val 1 Concentration = 0 or Val
2 Concentration = 0).
• Zero Level: Signal level when the laser is turned off.
