Correlates (Figure 2-2) directly with the log bar graph leak rate dis-
play. The units for the measurements are selected on the Units
Set-Up screen (see Section 3.1.5 "Units" on page 3-15).
Appears on the Home screen and represents the test port pressure
as measured by a thermocouple device mounted on the valve
block just below the test port. The pressure transducer and
associated electronics are intended to protect the leak detector
from damage due to over-pressure conditions. Use an external
pressure transducer if the test process requires a more accurate
monitoring of the test object pressure.
