ETUP FOR
Use this setup if you are connecting the T750 calibrator directly to other instruments
without the use of any shared manifolds.

To determine if the gas flow on the vent line is ≥ 5 SLPM, subtract the gas flow for each
instrument connected to the outlets of the T750 from the TOTAL FLOW setting for the
calibrator (see Section 2.5.5).
If the T750 has the optional O
3
800 cc /min (0.8 SLPM) of additional flow (see Section 2.5.5 or Figure 2-18).
EXAMPLE: Your system has two analyzers each requiring 2 SLPM of cal gas flow and
the T750 includes the O
10 SLPM:
10 SLPM – 2 SLPM – 2 SLPM - 0.8 SLPM = 5.2 SLPM
Therefore, the vent would require a gas line with an O.D. 3/8 inch.
