Set Molar Mass for ppmw Calculation

Use the MOL command to view and set the molar mass of the gas in the

measurement environment. The molar mass parameter is used in

calculating H

O ppm

Some typical molar masses are:

- Air 28.96 g/mol

- N

28.0134 g/mol

- O

32.00 g/mol

- SF

146.06 g/mol

MOL [n]<cr>

where

Molar mass (in g/mol) of the gas in the measurement

environment

Examples:

mol 146.06

Mol : 146.0600

mol

Mol : 146.0600 ?

NOTE

You can also set the

molar mass when you connect the DMT152 to the

MI70 indicator.
