2.3.8 Programming The Pump
1. When the “LAST” display following the blank
screen is showing, choose one of the programs, PC
or P1 through P6, by pressing
▲
or
▼
to present
the selected flashing “Px” in the display window,
where “x” may be a C or a number from 1 to 6.
2. Press the PROG button to view the value of the first
variable, Delay Time, represented by the “D” icon
in the display window. This variable controls the
number of minutes from the setting of the On/Off
switch to the On position until the occurrence of
the first air sampling run time. The “Clock” icon
will begin flashing to indicate that the programmed
variables are being changed.
3. To change the value of the Delay Time for the se-
lected program, press
▲
or
▼
to increment or dec-
rement the value, respectively, or simply go to
Step␣ 4. If either button is held down, the numbers
will change at an increasing rate of change after an
initial pause.
4. Press the PROG button to accept the displayed De-
lay Time value and present the value of the second
programmed run variable, the Run Time, which is
accompanied by the “R” symbol. The Run Time
variable is the number of minutes that the sampler
will run for data collection before going into the
Delayed Run state.
5. To change the value of the Run Time for the se-
lected program, press the
▲
or
▼
to increment or
decrement the value, respectively.
6. Press the PROG button to accept the displayed
Run Time value and present the value of the third
programmed run variable, the Delayed Run Time,
which is accompanied by the “D” and “R” symbols.
The Delayed Run variable defines the number of
minutes between successive Run Time intervals.
7. To change the value of the Delayed Run Time for
the selected program, press the
▲
or
▼
to incre-
ment or decrement the value, respectively.
8. Press the PROG button to accept the displayed De-
layed Run Time value and present the value of the
fourth programmed run variable, the Cycle Count,
which is accompanied by the letter “C” in the small
digit position. The Cycle Count variable defines the
number of times that the Run Time intervals are ex-
ecuted.
9. To change the value of the Cycle Count for the se-
lected program, press the
▲
or
▼
to increment or
decrement the value, respectively.
10. Press the PROG button to accept the displayed
Cycle Count value and return to the flashing “Px”
display. This completes the programming opera-
tions of the selected program.
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.
