2.3. General Information
2.3.1. General Information
The Nephelometer measures particulate in the air using a laser engine.
Laser light is scattered by the particles in the view volume and detected by
a photo detector. This information is then multiplied by a K factor and
displayed on the screen and logged as a sample event.
The Nephelometer logs each sample event into memory; data is
transferred to a computer using the companion software. A cable is
supplied for connection to the USB port on the user’s computer. Each
sample event records a time, date, serial number, environmental setting
and an average concentration.
Several special features have been included in the 80570 that make it
easy to use.
2.3.2. Environmental Factors
Environmental Factors allow the user to match the Nephelometer to
specific conditions of the area to be monitored. Each Environmental
Factor has a name and a correction factor (K factor) for the specific
environment. These Environmental Factors provide the best accuracy,
and are particularly valuable when diverse environments are measured.
Ten Environmental Factors may be stored in the Nephelometer; the ten
factors are selected by using the companion software and selecting from
the 99 user created factors in the software, each with name, description,
and correction factor.
2.3.3. Sheath Air
Air is drawn in through the top mounted inlet and then the sample air is
surrounded by a sheath of clean filter air. This sheath protects the sensor
from contamination. The inlet may be closed to keep particulate out of the
sensor during periods when the unit is not in operation.
2.3.4. Automatic Power Saving
The unit will power down when the unit is not sampling and no key press
or communication activity for 5 minutes.

.
2.3.5. Selectable Sample Modes
In MANUAL (M) mode a timed one minute measurement cycle begins and
upon completion of the measurement cycle, the collected data is stored.
During the measurement cycle the real time data is displayed, at the end
of the measurement cycle the average concentration is displayed until the
operator either pushes Start/Stop again or the Select button is
depressed.
In CONTINUOUS (C) mode samples are taken as above, however, the
unit will continue to make 60 second measurement cycles until the
Start/Stop sample key is depressed.
In STEL (S) mode 60 second samples are taken for a 15 minute period
and upon completion the unit will stop sampling.
2.3.6. Utility Software
The supplied software is designed to simplify set-up operations and to
download data records from the Nephelometer into a standard data file.
Refer to 360-0139-01 for software operation.

3. Trouble Shooting and Maintenance
There are no user serviceable parts inside of the unit.
3.1. Errors and Alarms
Certain operational failures are displayed and recorded in the Alarm Log. In the
event of one of the following errors, the error is shown on the second line of the
display. Typical display with error is shown below.
3.1.1. Battery Alarm
A low battery condition is checked for when the unit is sampling. When the
battery voltage goes below 6.0 volts the Sample will be stopped and Low
Battery will be displayed. This alarm is logged in the Alarm Log.
3.1.2. Laser Current Error
Laser current is measured (IOP) and if the current exceeds a preset value
the alarm is triggered. As the laser degrades, it takes more and more
current to maintain the same output level. When it fails altogether, the
current will go to maximum.
The unit will display SENSOR FAULT and operation will be suspended.
Only the Power button will be active to turn off the unit. This is due to the
nature of the fault. The unit is not capable of taking valid measurements if
this occurs. This alarm is logged in the Alarm Log.

3.2. Battery Pack
WARNING: There are no user serviceable components inside the
Nephelometer. Do not attempt to change the internal battery pack. The wrong
battery pack could cause serious damage, a fire, or explosion. The
Nephelometer should be sent to a service center where a factory qualified person
would change and properly dispose of the battery pack.
This device contains Lithium Ion battery technology and should only be charged
with the supplied 8.4 VDC Lithium Ion Smart Charger unit. Never connect a
power source greater than 8.4 VDC to this device.
When the battery is low enough to need charging, a “Battery Low” message is
displayed on the display and the pump will not turn on when the Start/Stop key
is pushed.
To charge the battery pack, plug the 8.4 VDC Lithium Ion Smart Charger unit into
an AC power outlet. The module is universal and will work with power line
voltages of 100 to 240 volts, 50 to 60 Hz. Take the barrel connector on the end of
the cord coming from the Charger module and plug it into the charger input
socket on the side of the Nephelometer (See section 2.2 Familiarization). To fully
charge a discharged battery pack should take around 2.5 hours.
NOTE: After the batteries are completely charged, the smart charger will stop
charging. The next time it is used, it must be disconnected from AC power, and
then reconnected to the AC outlet to restart the charge cycle.
The battery pack inside the Nephelometer when fully charged will power the
Nephelometer for about 10 hours of continuous use. Under normal intermittent or
manual operation however, there is considerably less battery drain and up to 25
hours of use is possible.
If the Nephelometer is to be used powered by its battery pack on a daily basis,
connect the charger after every few days of usage, or as needed.

Page 18 of 22 Nephelometer Operation Manual 360-0138-01rB
3.3. Filter
The Nephelometer has a 0.2 micron filter to produce the clean air for the sheath
system. This filter will normally need to be changed on an annual basis but may
require a more frequent change if used in extremely dirty environments.
Remove the filter element by unscrewing the filter holder cap. Replace filter and
install filter holder cap.
