General Information:
Operation
A programming card is supplied inside the LS-MC, a copy is on page 10.
The programming card shows the pre-programmed parameters
that are held in the memory.
Power Up
On power up, the LS-MC will take a few seconds to initialise, then the display will run through a set-up routine, showing a full set of
figure eight’s, then the software revision and finally a full set of zeros whilst the microprocessor identifies the correct return echo and
confirms this repeats enough to be acceptable.
The instrument is now ready for use, and is set-up using the 3 coloured push buttons.
Refer to the programme menu which is on
page 10
, and also in the instrument itself on a card tucked between the electronics housing
and the body.
Display Units
The LS-MC default value is meters.
The display units can be changed using the blue button
. Simply hold the blue button
down for 10 seconds and the units will
change to the next option in the following sequence :
Metres to Feet to Inches and back to Metres again.
This is indicated by the position of the decimal point in the displayed value :
Once the units have changed from default to the next option, the blue button
can be released, in which case the new units selected
are confirmed, or the blue button
can continue to be held down, in which case the next units option is given after a further three
seconds.
When the display units have been programmed, please note that you must use the same units when programming in the bottom
reference, 4 and 20mA points.
The 4-20mA output may be set to operate over all or just a part of the total measuring range. There is no theoretical limit on the
minimum span of the current output, although in practice a span below 100mm is not recommended. With small spans, be aware that
a high value of damping will greatly affect the performance of LS-MC.
The 4mA level may be set above or below the 20mA level to suit the monitoring or control equipment.
Note: The LS-MC measures and calculates at all times in metres. The units of display are derived as a last operation using a pre-
programmed conversion factor.
