times, six if in LOG mode) before the DUSTTRAK monitor goes back into the
measuring mode.
PRINT Key
Use the PRINT key to print information on the optional Portable Printer.
The information printed will be different depending on what the D
USTTRAK
monitor is currently doing.
When the D
USTTRAK monitor is displaying real-time readings, pressing the
PRINT key causes the reading to be printed along with the time and date.
Each time the PRINT key is pressed, one reading will print. The reading
printed reflects the current time-constant; therefore, it is the same as the
displayed reading.
When the D
USTTRAK monitor is displaying any statistic, pressing the PRINT
key causes the current statistics to print.
When the D
USTTRAK monitor is in one of the LOG modes and is idle
(“%MEMORY” is displayed), pressing the PRINT key causes the logging
setup for the current LOG mode to print.
During the power-up sequence, if you press and hold the PRINT key after
the time is displayed, a printout will be generated showing certain system
information (printer must be connected and turned on).
SAMPLING MODE Key
The SAMPLING MODE key allows you to select among the four sampling
modes: Survey, LOG 1, LOG 2, and LOG 3. Each time you press the
SAMPLING MODE key, the D
USTTRAK monitor sequences to the next
mode. When the D
USTTRAK monitor is in Survey mode, the current
measurement will be shown on the display. When one of the LOG modes is
selected, the LOG mode number, i.e. LOG 1, LOG 2, or LOG 3 will be
displayed along with the percentage of free memory available.
Survey Mode
When the D
USTTRAK monitor is first turned on, it will always be in
Survey mode. Survey mode allows you to make real-time measurements
of aerosol concentration, and to obtain statistics for that sample. The
statistics include the average, minimum, and maximum values, as well
as the elapsed time for that sample. Individual data points are not
recorded (this can be done in any of the LOG modes). Each new sample
taken in Survey mode clears the previous sample data from memory.
Data taken in Survey mode remains in memory until another sample is
made, or until samples are taken in one of the LOG modes. Turning the
