2. Operation
This section gives examples of how to connect and use the
instrument. Before you start:
• Read and understand section "Safety" on page 1.
• Do not use a damaged instrument.
2.1 Pressure Connections
CAUTION
To prevent damage, do not apply
torque to the body of the instrument. If
available, use the flat faces on the pressure
connector to hold the instrument in position.
Use an applicable method to seal the pressure
connections, and then tighten to the applicable torque
(Figure 1).
Note: If the instrument uses G1/8 connections, and the
pressure is ≥ 1500 psi (100 bar), connection method (b) is
mandatory.

4 (G1/8 only) Applicable bonded seal.
5 Reference port connector: M5 or 10-32 UNF (Table 11)
Maximum torque: 1.5 lbf.ft (2 Nm)

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).
4. Before you disconnect the instrument, isolate and
bleed the system.

Figure 2: Example Configuration - Measure Pressure
The examples in Figure 2 shows:
• How to measure one or two pressures in a system.
• How to measure pressure difference.
Note: ∆P = High range IDOS - Low range IDOS. If
Pressure (p2) > Pressure (p1), the result is negative.
2.4 Leak Test
To do a leak test on a pressure system:
1. Connect the instrument (Figure 3) and, if necessary,
adjust the Set Up (Table 1).
2. Select an applicable leak test from Select Task
(Table 2 & Table 3) and, if necessary, adjust the
Settings (Table 4).
3. Set the period for the leak test (Table 4).
4. If necessary, do a zero correction (Table 4).
5. To start the leak test, select Start (). When the test
is finished, the instrument calculates the leak rate in the
applicable units/minute.
