of 10 minutes, results in a 1 minute test performed every 10 minutes. Setting the
interval to a value less than the Test Duration (for example zero) results in a new
test being started immediately a test finishes.
Log Continuous controls whether tests are logged during continuous testing. This
is to avoid the test log being cluttered by potentially large numbers of unwanted test
results. If Log Continuous is not selected, then only the "final’’ test in a sequence
is logged (see Alarm Modes section and "Stop Testing When Clean’’ below).

If continuous logging is used, then the Log Interval can be set to control the pro-
portion of tests that are actually logged. For example the ICM could be set to test
every 10 minutes, but only log a result hourly. The log interval, test interval and
test duration are distinct parameters that work together to control the test and data
logging. So that for example a test duration of 2 minutes, a test interval of 10 min-
utes, and a log interval of 1 hour could be set. This would result in 2 minute long
tests, repeated every 10 minutes, with a test logged hourly.
Start Testing Automatically sets the ICM to begin a test soon after it is powered up.
This is ideal for unattended systems.
Stop Testing When Clean is a feature intended for cleaning rigs or "filter trolley’’
type applications. The ICM continues testing until the fluid is "clean’’, at which
point an alarm is signalled and testing stops.
Confirm Target Level Before Stopping This helps to ensure that a test sequence is
not terminated too soon, when there are still a few large particles in the system.
When selected, two successive "clean’’ results are needed before testing halts.
12.8 Alarms
The ICM has two switched "alarm’’ outputs that can be used to signal external
equipment in various ways, according to the test results and the alarm settings.
There is also a multi- colour front panel light which indicates how the result com-
pares to the set alarm thresholds.
The alarm settings are comprehensive and flexible, allowing the ICM to be used in
many different scenarios.

This feature is intended for a "Filter Trolley’’ type application where system runs a pump until the oil
is sufficiently clean. Typically only the final "clean’’ result requires logging.
