SDELAY
With the sdelay command you can set delay (response time) for user port
(RS-232 or RS-485), or view currently set delay value. Value
corresponds to tens of milliseconds (eg. 5 = 0.050s minimum answer
delay). The value can be set between 0...254.
Example:
>sdelay
Serial delay : 0 ? 10
>sdelay
Serial delay : 10 ?

Sensor Functions
AutoCal
To obtain the best possible accuracy in measurements taken in dry
environments, DMT345 and DMT346 have a built-in AutoCal feature.
During the AutoCal, the transmitter adjusts the dry-end reading to
correspond to the calibrated values. This is a unique and patented method
to avoid errors in accuracy when monitoring low dewpoints.
The AutoCal is carried out if the following criteria for the measurement
environment are fulfilled:
- Relative humidity must be <10 %.
- Temperature must be 0<T<140 ºC.
- Humidity environment must be stable. The maximum change in the
dewpoint can be 2 ºC in 15 seconds.
NOTE
AutoCal cannot operate if the above conditions are not fulfilled.
