Description
1
Tech Password
Used to change the password that is required to access the tech webpage.
2
Date/Time
Used to set the internal date and time of the instrument. This date and time will
be stamped to each particle record.
3
Set Location
Use to enter an ASCII string to describe the location of the instrument.
4
Addressing
Used to set the addressing of the instrument. The instrument needs to be
rebooted for these changes to take effect. The factory default IP address for the
instrument is 192.168.200.90.
5
Alarm Threshold
Used to set a threshold that will trigger the particle alarm. A threshold can be
set for each of the three channels.
Sample/Hold Time
Used to set the sample time and hold time of the instrument. These will drive
the operation of the instrument when in “automatic” mode. For example and
sample time of 6 seconds and a hold time of 0 seconds will take consecutive 6
second samples with 0 seconds between each reading.
6
Select Channel
Used to select the three particle channels that will be reported by the
instrument. Any three combinations can be selected.
Enable Differential mode
Used to put the instrument in differential mode. If this check box is not selected,
then the instrument will report particle counts in cumulative mode.
7
Sample Data
Used to read back records from the 3000 record buffer.
8
View buttons
Used to view the data in the buffer.
<View all> will output all particle readings currently stored in the 3000 record
buffer.
<Clear Current> will delete the latest record stored in the buffer.
<Clear All> will delete all records stored in the buffer.
9
Control Button
Used to control the instrument.
<Auto> will put the instrument in automatic mode where it will take readings
according to the sample and hold time set in section 5.
<Manual> will start the unit counting particles that will continue unit the <Stop>
button is pressed.
