SAMPLE
The SAMPLE screen configures the number of cycles, count times and
volumes during a sample run. See Figure 5-16.
Figure 5-16 Sample Timing Configuration Screen
• CYCLES: The number of cycles is set to determine how many
times the instrument samples the air in a single location. This is
applicable 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.
Press 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/save the Cycles.
• DELAY: The Initial Start Delay (hh:mm:ss) is the time between
when the START button is pressed and the unit actually starts
counting.
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 23 hours, 59 minutes and 59 seconds.
Press the DELAY button; enter the initial delay time in hours,
minutes and seconds using the numeric keypad. 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.
• HOLD: The Hold Time (hh:mm:ss) is the time between count
cycles when the instrument is not counting particles. The maximum
hold time is 23 hours, 59 minutes and 59 seconds. This field on the
MAIN screen will count down to indicate how much time is left for
the Hold period.
Press 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.
