1)
Using a pointed instrument, press MODE/HOLD
button. Display shows “LAST” [1A] followed by
screen showing current program number [1B], fol-
lowed by screen showing the run time,
“R”
, and
the percentage of time the last sampling run var-
ied more than
±
5% from set flow rate. The three
screens repeat.
NOTES
If CAL is displayed instead of LAST, press the MODE/
HOLD button twice more to display the LAST run data.
2)
Press the
▲
or
▼
buttons while “LAST” is dis-
played [2A] to change the program number up-
ward or downward [see 2B]. Continue to press the
▲
or
▼
buttons to further increase or decrease
the program number (Px, where x can be “C” or a
number from 1 to 6).
3)
Press the PROG button to view the current Delay
Time (represented by “D” icon in the display win-
dow [3A]). The clock icon is flashing. Press the
▲
or
▼
buttons [3B] to either increase or decrease
the Delay Time [3C].
The Delay Time is the number of minutes after
the pump is turned on before it actually starts
sampling.
4)
Press the PROG button again to view the current
Run Time (represented by “R” icon in the display
window [4A]). The clock icon is flashing. Press the
▲
or
▼
buttons [4B] to either increase or de-
crease the Run Time [4C].
The Run Time is the number of minutes the pump
will sample before stopping and going into Run
Delay mode.
5)
Press the PROG button again to view the current
Run Delay Time (represented by “D” & “R” icons
in the display window [5A]). The clock icon is
flashing. Press the
▲
or
▼
buttons [5B] to either
increase or decrease the Run Delay Time [5C].
The Delayed Run Time is the number of minutes
between successive Run Time intervals.
6)
Press the PROG button again to view the current
Cycle Count (represented by “C” icon in the dis-
play window [6A]). The clock icon is flashing.
Press the
▲
or
▼
buttons [6B] to either increase
or decrease the Cycle Count [6C].
The Cycle Count variable defines the number of
times that the Run Time intervals are executed.
7)
Press the PROG button again to accept the pro-
gram changes and return to the flashing “Px” dis-
play [7A]. This completes the programming phase
for this selected program number
NOTE
If the Run Time and Cycle Count variables are large
enough to result in a total run time of more than 9,999
minutes, the unit will remain in the Cycle Count pro-
gramming mode with a flashing “E” in the small digit
area, until a value for Cycle Count is acceptable when the
PROG button is pressed.
Once the pump is programmed it will default to the
program number used for the last sampling run when
the display is turned on [1].
To switch to another program number without making
any changes, follow Steps 2A and 2B. Continue press-
ing the PROG button only in Steps 3 through 6 until
the display shows the flashing program number [7A].
