• This parameter defines the measuring time of the change in

dewpoint prior to the auto-calibration (see the parameter 0D[

G7GS.

• If the setting is correct, press ENT.

• If the setting needs to be changed, press CL and change the value

with arrow keys. Acknowledge the setting with ENT.

• This parameter defines the maximum correction (%RH) the

transmitter does during each auto-calibration cycle. If the

correction exeeds the limit, the calibration is ignored. Note that

normally, this parameter does not have to be changed.

• If the setting is correct, press ENT.

• If the setting needs to be changed, press CL and change the value

with arrow keys; acknowledge the setting with ENT.

• This parameter defines the time the output values prior to the auto-

calibration are frozen after the calibration. The time is for sensor

temperature stabilization.

• If the setting is correct, press ENT.

• If the setting needs to be changed, press CL and change the value

with arrow keys; acknowledge the setting with ENT.

NOTE

Auto-calibration takes place only when the security lock jumper is

connected. During auto-calibration, the reading on the display is

frozen.

NOTE

If the process pressure differs from the normal ambient pressure, the

value has to be entered in the transmitter memory to ensure the best

possible measurement accuracy. The pressure setting is used for

pressure compensation of the DMP248 transmitter.
