[quantity]
Type one or several of the following quantities: TD/ TDF/
H2O/PW/RH/TW/A/ANTP/X/H/DT/T/P/FLOW/+TDF/
+TD/+PW
TD = dewpoint temperature
TDF = dewpoint/frostpoint temperature
H2O = humid air volume/dry air volume
PW = water vapour partial pressure
RH =relative humidity
TW =wet-bulb temperature
A = absolute humidity
A = absolute humidity in NTP conditions
X = mixing ratio
H = enthalpy
DT = difference of T and Td/f
T = temperature
P = pressure
FLOW = sample gas flow rate
+TDF = error limit value
+TD= error limit value
+PW = error limit value
[u]
[u1...u9]
Type U to show a unit text after a quantity field. By typing
U1 results unit text with only one letter, U9 results space-
padded nine letters text. If needed, change the unit by using
the separate command UNIT (or by using the display
menu). This field shall be defined only after quantity field.
[status]
Type STATUS to insert the state of a dewpoint
measurement system.
The state can be one of the following: STOP (water content
measurement not operating, OK (normal operation), WAIT,
ERR (error in measurement).
[date]
Type DATE to have a date. The date is shown in form of:
yyyy-mm-dd.
[time]
Type TIME to have a time shown. The time is shown in
form of: hh:mm:ss.
[addr]
Type ADDR to have the device address (set with the
ADDR command).
