-DOT Function
−Dot allows negative dot measurements with zeroing to the Base Dot
value. −Dot can be calculated for a Base equal to 100% or can be
adjusted to a value equal to a known Dot size (ex. 97%). -DOT is
normally used for negative films.
-DOT MEASUREMENT
1. Repeatedly depress the [
FUNCTION] key until "-DOT" is displayed.
Previous Dot value is displayed.
2. Select color (ortho or ultraviolet).
3. Zero unit to a Base Dot or Base Fog of film, by pressing [
ZERO]
while measuring this area of the film.
4. Measure the film. −Dot value is displayed. Repeatedly depress
[
FUNCTION] until "+DOT" is displayed. Previous Dot value is
displayed.
Sequence (Disabled from factory)
The Sequence function allows a setup of a measurement sequence to
meet the job requirements. Once a sequence structure has been setup
(see "Setting the Sequence Structure" in Chapter 5 for setup procedure)
the 361T will automatically select the function and advance to the next
step, step by step. Once in the Sequence function, a depression of the
Read button advances to the next step. However, the 361T can
increment or decrement thru the steps by depressing and holding dc
[
ZERO] key and then depressing d [FUNCTION] key to decrement or
c [COLOR] key to increment.
IMPORTANT! The Density/Dot value for each sequence step is
displayed during the measurement (Read button depressed).
When the Read button is released, the display shows the next
step to measure. If you desire to view the Density/Dot value for
the last step measured, press the [ZERO] key to view it, and
then press [ZERO] again to return.
NOTE: During sequence operation, look at the display and
make sure each measurement is correct before releasing the
Read button to proceed to the next step.
The example Sequence procedure below shows a sequence that was
setup using two steps, and it starts out at step1. When entering sequence,
the function will always start at the lowest step enabled.
