L60iF Issue 9 November 2018 4
3. Installation and operation
3.1 Installation
The L60iF is a portable instrument with a permanently connected mains cable. Unless otherwise marked, it is
designed to operate from a 110V 50Hz supply. The power cable uses the standard colour code of
Live - Brown; Neutral - Blue; Yellow/Green – Earth
When locating the sampler it is important that the rear of the unit should not be too close to a wall etc.,
which could impede the free flow of cooling air through the Sampler. No other installation procedure is
required.
If the DC/AC converter is to be used, connect the Sampler to the 3-pin socket on the converter. Then
connect the 12V input leads securely to a suitable battery.
NOTE that the operating current is approximately 15A. For example, a fully charged 12V 85Ahr battery will
run the L60iF for about 5 to 5½ hours.
3.2 Preparation for sampling
3.2.1 Selection of test routine (Refer to flow charts at rear of manual)
The Sampler will be in Operator mode, if switched on with no buttons pressed.
In operator mode, selecting Run test will display the routine set up in Supervisory mode. Selecting confirm
will run this test. Unless cancelled, the test will then run as described on the display. If an alarm condition
causes a test to stop, the results of the test until stoppage can be displayed, and the system can then be
returned to the opening menu by pressing end.
To change the type of test, Supervisory mode must be entered as follows. With the instrument switched OFF,
press and hold the Up (n
) and Down (
) keys and switch the unit ON. The following options will then be
available by scrolling up or down.
Test results
The results of previous tests can be displayed in turn for reference. (The operator can access the
most recent test only, in case the results were not noted, or there was a power failure when the
operator was not present.). Each result is displayed with a code to indicate how the sample ended.
Where a sample has several parts as a result of power failures the separate parts can be viewed
labelled PF and a summary result is also displayed labelled FI.
A sample stored in a single uninterrupted run is labelled OK.
