Note: If the instrument uses G1/8 connections, and the pressure is ≥ 1500 psi (100 bar),
connection method (b) is mandatory.

2.2 Communications Port Connections
Use the communications port (Figure A1 - item [9]) to attach an IDOS Universal Measurement
Module (UMM).
When you attach the cable from a UMM (Figure 8), the instrument automatically changes the
menus to give you all the applicable options (Table 2 & Table 3).
2.3 Measure Pressure
To measure the pressure or the pressure difference (if there are two IDOS pressure ranges).
1.
Connect the instrument (Figure 2) and, if necessary, adjust the Set Up (Table 1).
2.
Select an applicable pressure task from Select Task (Table 2/Table 3) and, if necessary,
adjust the Settings (Table 4).
3.
If necessary, do a zero correction (Table 4).
