Chapter 2. Initial Setup
2.6.0d Selecting Mass Flow Units
1. Scroll to the desired Mass Flow units for the flow rate display and press
[Enter].
The available units for this prompt
are determined by the selection made at the System Units prompt. See Table 9 below.
2. Scroll to the desired Mass Flow Time units for the mass flow rate display and press
[Enter]
.
3. Scroll to the desired number of Mdot Decimal Digits (digits to the right of the decimal point in the mass flow rate
display) and press [Enter] .
4. Scroll to the desired Mass (Totalizer) units for the totalized mass flow rate display and press
[Enter]
. The available
units for this prompt are determined by the selection made at the System Units prompt.
5. Scroll to the desired number of Mass Dec. Digits (digits to the right of the decimal point in the totalized mass flow
rate display) and press [Enter].
After completing the above steps, the XGM868i returns to the
Channel PROGRAM
