Setting the Visual and Audible Alarm
The Visual Alarm conditions can be viewed from either a red, yellow or green LED that
lights 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.
The Audible Alarm turns the beeper on the gauge either on or off based on the same
alarm conditions used for visual alarm stated above.
Setting the Vibra Alarm
The gauge will physically vibrate when the Vibrating Alarm is active based on the same
alarm condition used for visual alarm. The Vibrating Alarm, noted as
vib
on the gauge
display, can be enabled with varying alarms and alarm conditions as shown on the
screens below:
