USING THE INSTRUMENT IN CUSTOM CHANNEL
MODE
4.1 OVERVIEW
Customer channel operation provides for increased accuracy but requires
that a "once off" set-up is performed for each lacquer type used. In use a
channel is calibrated exactly to the known sample of a given lacquer type.
Readings of that lacquer type are then taken when that channel or lacquer
number is selected. The instrument can be calibrated to cope with up to 99
different lacquer types.
To prepare the instrument to cope with a new lacquer it is necessary to
perform a set-up, however, as the set-up data is permanently stored, this
operation need never be repeated.
4.2 SETTING UP A LACQUER TYPE
When the gauge is first received no lacquers will be set-up in its memory and
this situation will be returned to if a master reset is performed (see 2.7). In
this state the unit is incapable of taking readings.
To enter a lacquer type first enter set-up mode as described in 2.11
(simultaneously press
CALIBRATE
and
LACQUER NUMBER
followed by
the 4 digit password). When this has been done the SET-UP indicator will
illuminate and the lacquer number display will show the last used lacquer
number, or if none are programmed, it will show lacquer number 1.
Next press the
LACQUER NUMBER
key, the display will indicate two
question marks and a number in the range 1 to 99 must now be chosen to
assign to the particular lacquer type that is being set-up. If you wish to see
which lacquer numbers are already in use, repeatedly press the up or down
arrow keys and the display will cycle through all lacquer numbers already
programmed.
Enter a 1 or 2 digit lacquer number followed by the
ENTER
key and the film
weight display will then show 4 question marks.
It is now necessary to enter the value of the known sample for that lacquer
type (1 to 4 digits including decimal point with 1 or 2 decimal places as
selected - see 2.8) followed by the
ENTER
key.
That channel has now been set-up, to set-up a further channel press the
LACQUER NUMBER
key again or to finish setting up press the
END
key and
the unit will drop back to MEASURE mode.
