OPERATION

NB. If User 1, 2 or 3 is selected as the carrier gas then a new parameter box

will appear underneath the carrier gas toggle box called ‘User Gas’. This can

be seen below.

Figure 29

Measurement Screen

When the User Gas option is selected from the carrier gas list, the user can enter the

user gas settings, using the User Gas Setup page which is opened. See Appendix F for

further information on calculating User Flow Correction Factors.

3.7.1.2 DP Calculation Method

Selects the calculation method used for dew point and lbs/MMscf. Options are:

•

IGT - as per IGT Bulletin #8

•

ISO - as per ISO18453

• Ideal

Gas

3.7.1.3 Pressure Input

Selects the pressure source. Options are:

• Atmos.

• Fixed

• External

If the external option is selected the ‘Fixed’ selection box is hidden and replaced with

the ‘Ext. 4mA’ and ‘Ext. 20mA’ selection boxes as shown below:
