[x] = formatter string

The formatter string consists of parameters and modifiers. The maximum length of the form string is 74 characters. When entering the command, use the abbreviations of the parameters. The parameters are presented in Table 1, and modifiers in Table 2.

FORM /<cr> Return to default format.


form 4.2 TDF #r #n
form 3.1 “H2O= “ ppm “ “ U3 #r #n
Table 1. FORM command parameters
Parameter Description
TDF Dew point / frost point temperature
PPM Water content in parts per million
PPB Water content in parts per billion
PPMW Water content in parts per million by weight
For accurate ppm, ppb, or ppmw reading, you must compensate for the pressure and molar mass of the process gas.
