Operation - Communications port connections
Use the communications port (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 2/3).
Operation - 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 2/3) 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 show:
• 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.
Operation - 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 2/3) 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.
6. Before you disconnect the instrument, isolate and
bleed the system.
