At this point the
LED
is
turned off
and the screen flashes a
FINISHED
message. The screen then displays the
overall test result. After the
Green Tick
is tapped some additional test data is displayed which may aid
maintenance personnel to identify any emission-related faults in the engine or fuel management system.

Continuous Measurement
The DPM-RT-2 also has a capability to continuously measure and record DPM concentration. This feature is
very useful if you wish to record DPM over an extended period, such as on-equipment monitoring during
normal workloads.
4.8.1
Test Details
The test’s details are a set of text parameters that allow you identify this
test in the list of previous results. It also allows the user to associate a
piece of equipment with the test.
Tapping on the buttons will bring up an on-screen keyboard for the user
to enter in the required information.
4.8.2
Zero Instrument
Prior to any test, the instrument initiates an auto-zero procedure, prompting the operator to ensure that the
sample probe is in relatively clean air (for instance, not directly downstream from the exhaust of an
operating engine). This procedure ensures the exhaust paths into the machine are clear from exhaust fumes.
