Complete the following steps to configure the particle counter.
1. Open the SetupUtility.exe file. The utility program will open (refer to
2. Find the Comport field. If necessary, change the COM port to match the port on the
PC that the particle counter is connected to. Click
read the data that is stored in the instrument.
3. Make sure that the data in the Instrument Information section is accurate. This
section shows the instrument model number, communication option, firmware version
and communication address (if applicable).
4. Change the parameters in the General section as is necessary. Refer to the
parameter descriptions that follow:
•
Count Mode (for pulse, Modbus or FXB only)—set to differential or cumulative
(refer to
section 4.2.3 on page
•
System Date/Time—enter the current date (YYYY/MM/DD) and time
(HH:MM:SS, 24-hour format).
•
Sample Timing: Sample—the length of time that data is collected for each
sample. The default sample time is one minute (00:01:00).
•
Sample Timing: Hold—the length of time that data collection is stopped between
samples. Use the Hold time to stop data collection during maintenance
procedures. The default Hold time is 0 (00:00:00).
•
Count Alarms—set the number of counts for each size channel that will trigger a
count alarm.
Note: The pulse unit uses only 2 channels for particle counts.
•
Sample Mode—set to Auto.
•
Flow Units—set to CFM (cubic feet per minute) or LPM (liters per minute).
5. The Diagnostics section can be used to make sure that the wiring to an external
light stack is correct. Set the Indicator LED to flash or not flash for one of the colors.

•
Analog—set the count value for each channel that corresponds to the 20 mA
output signal (default = 1000).
