Digimet 3000 display will blink when a
parameter value falls outside the
desired limits. This will give guidance to a
user as to a potential problem with a
pulsator and/or an indication of values that
are not appropriate.
Limits for the following Pulsator Ratio
parameters can be set:
• Minimum and Maximum limits can be
set for Maximum Vacuum per Pulse; A,
B, C & D Phases; and Pulses per
Minute.
• A Maximum limit can be set for B
Fluctuation and a Minimum limit can be
set for Minimum Vacuum per Pulse.
When viewing data in real time or
viewing stored data, the values that are
outside the set limits will blink on the
Digimet display.
To set limits, first go to the Utility Menu
which is the Function Menu number 5.
Press the Enter key, then the down arrow
key to Set Pulsator Limits which is number
11 in the Utility Menu. 11 Set Pulsator
Limits is the last item in the Utility Menu.
Then press the Enter key.
To set limits, move the arrow at the left, by
pressing either the Up or Down arrow key.
When the arrow is beside the parameter
that you desire to set limits, press the
Enter Key. An E will appear in the upper
right corner of the Digimet display
indicating that you are in the Editing Mode.
Use the Up or Down arrow keys to set the
desired values.
Limits for the following Pulsator Ratio
parameters can be set:
B Fluc Max can be set from 0.00 to 3.00 in
increments of .50 inches Hg.
Max Hi Vac/Pulse can be set from 5.50" Hg to
16.00" Hg in increments of 0.50 inches of Hg.
Min Hi Vac/Pulse can be set from 5.00" Hg to
15.50" Hg in increments of 0.50 inches of Hg.
Min Vac / Pulse can be set from 0.00" Hg to 4.00"
Hg in increments of 0.50 inches of Hg.
Max A Phase can be set from 30 to 300 in
increments of 1 msec and must be at least 10
msec greater than Min A Phase.
Min A Phase can be set from 20 to 290 in
increments of 1 msec and must be at least 10
msec less than Max A Phase.
Max B Phase can be set from 110 to 750 in
increments of 1 msec and must be at least 10
msec greater than Min B Phase.
Min B Phase can be set from 100 to 740 in
increments of 1 msec and must be at least 10
msec less than Max B Phase.
Max C Phase can be set from 30 to 500 in
increments of 1 msec and must be at least 10
msec greater than Min C Phase.
Min C Phase can be set from 20 to 490 in
increments of 1 msec and must be at least 10
msec less than Max C Phase.
Max D Phase can be set from 110 to 500 in
increments of 1 msec and must be at least 10
msec greater than Min D Phase.
Min D Phase can be set from 100 to 490 in
increments of 1 msec and must be at least 10
msec less than Max D Phase.
Min PPM (pulses per minute) can be set from 20 to
198 in increments of 1 PPM and must be at least 2
PPM less than Max PPM.
Max PPM can be set from 22 to 200 in increments
of 1 PPM and must be at least 2 PPM greater than
Min PPM.
Press the Enter key to Save that
parameter. To set another parameter, use
the same procedure. To exit Set Pulsator
Limits, press the Menu key.
If measurement Units is set to kPa then
the pulsator parameters must still be set in
Inches of Mercury but readings will
respond to their kPa equivalent.
