Visual and Audible Alarm
The Visual Alarm conditions can be viewed from either a
red, yellow or green LED that light up under the
F1
,
F2,
or
F3
keys on the keypad.
As an example, when using the 5 step English test block
with thicknesses of 0.100, 0.200, 0.300, 0.400 and 0.500
inches, if you enter alarm high-low you will first need to
enter the high value. Enter 0.500 and press enter. Next
you will need to enter the low value of 0.100 in. The
display will ask you to enter the percent reading of the
high low. The gauge will default to 20% (this can be
changed with the up or down keys), so any reading within
20% of the high value (approaching high, between 0.400
and 0.499 as 0.400 is within the 20% range of 0.500.) will
result in the yellow keypad lighting up. Also, any reading
above the low value of 0.101 and 0.120 will result in the
yellow F2 keypad lighting up as you are approaching the
minimum
So, in
Alarm
mode, choosing a non-zero percent value
provides the user with warning for readings approaching
the selected percent value of the high or low limits. For
example, if the alarm value is 0.100" and 20% is entered
as the “percent value”, reading from 0.101" to 0.120" will
result in the
F2
“yellow” key being illuminated. Also,
reading less than 0.100" will result in the F1 key “Red”
being illuminated and greater than 0.120" will result in
the
F3
“Green” key being illuminated.
