• CYCLES: The number of cycles is set to determine how many
times the instrument samples the air in a single location. This is
used only in AUTO mode. The range is 0 - 999. When Cycles is set
to 0, the instrument will continue running samples indefinitely until
the STOP button is pressed.
Select the CYCLES button; enter the number of desired cycles
using the numeric keypad on the right. Press ERASE to erase a
number, if needed. Press ENTER to set the Cycles.
• DELAY: The Initial Start Delay (hh:mm:ss) is the time between
pressing the START button and the unit actually starting counting.
Note:
The pump starts
immediately when START
is pressed. In order to
operate properly when a
Delay is set, the Delay
should not be less than 5
seconds.
The Initial Start Delay gives the operator time to exit the area under
test so that the measurement is taken under a controlled condition.
The maximum delay time is 99 hours, 59 minutes and 59 seconds.
Select the DELAY button; enter the initial delay time in hours,
minutes and seconds using the numeric keypad on the right.
After the value is entered, press ENTER.
Note:
If the Hold time is
set to 00:00:00 in Auto
Mode, the instrument will
run the samples according
to the sample time and the
# of cycles, but with no
hold time in between
cycles.
The maximum hold time is 99 hours, 59 minutes and 59 seconds.
This field will count down to indicate how much time is left for the
Hold period.
Select the HOLD button; enter the time in hours, minutes and
seconds using the numeric keypad on the right. Press ERASE to
erase a number, if needed. Press ENTER to set the Hold Time.
Note:
If the Hold time is
greater than one minute,
the pump will shut off
during the specified hold
time.
• HOLD: The Hold Time (hh:mm:ss) is the time between count
cycles when the instrument is not counting particles.
Note:

Sample Time is
23:59:59.

seconds using the numeric keypad on the right. Press ERASE to
