Syntax Description
a.aaaaa
Range 0.00001 ... 1.0
1.0 = No filtering, latest measurement is output without averaging
0.5 = Average of last two measurements
0.1 = Average of approx. 16 measurements (default)
Example (show current setting):
filt
Filter : 0.10000 ?
Example (set filtering to 0.5):
filt 0.5
Filter : 0.50000
7.8.3 Set Pressure Compensation Value
The pressure of the measured system must be known for accurate dew point and ppm
measurement. The pressure compensation value has been set at the factory according to the
order form. You can view and set a new value using the PRES command.
Command XPRES should be used if the value is changed frequently. The value set using the
XPRES command overrides the PRES value, but it is not retained at reset. When the XPRES is
set to 0, the last value set with PRES is used instead.
It is enough to set an approximate pressure value (±1 bar) to meet the accuracy
specification of the DMT143.

Description
pp.ppppp
Absolute pressure (bar

) in the measuring point.
Range 0.001 ... 50 bar.
Example (set pressure compensation value to 3 bar):
pres 3
Pressure : 3.000 bar
