GENERAL INFORMATION
Product Description
The Model 3150 Suspended Solids Analyzer is a handheld analyzer designed for the measurement of
suspended solids in aqueous solutions. The microprocessor-based electronics of the Model 3150 analyzer
provide a high degree of flexibility and ease of use. The instrument is designed to operate in a variety of
applications. The sensor operates on the principle of single gap light absorption as a means of detecting the
presence of suspended solids.
The Model 35 sensor has been designed for medium ranges (0 to 30,000 mg/l) as commonly found in
aeration basins and activated sludge lines of wastewater treatment plants. The Model 35L sensor has been
designed for low ranges (0 to 1500 mg/l) as commonly found in effluent streams. Both sensors utilize an
infrared emitter to minimize color effects and compensates for emitter variations due to temperature by
measuring source brightness.
The Model 3150 has built-in data logging. Up to 50 points may be logged with a time stamp. Each point
may be labeled with a six character location description.
Packaging
The analyzer is housed in a watertight handheld enclosure and is designed for harsh environments.
Batteries and Charging
The Model 3150 is powered by a three cell rechargeable NIMH battery pack. A battery charger is included
with the Model 3150. The red LED on the charger’s connector indicates the batteries are in quick charge
mode when illuminated or trickle charge when not illuminated. Fully discharged batteries will take about four
hours to charge. The Model 3150 may be connected to the charger for extended periods of time without
damage.
A fully charged battery can provide approximately 12 hours of continuous use. A low battery message
appears on the display when recharge is necessary.
Automatic Shutoff
If no keys are pressed, the Model 3150 will automatically shut off after 15 minutes.
DisplayBacklighting
The Model 3150 has a backlit display, but this backlighting is the main power consumer of the analyzer.
To conserve battery power, this backlight turns itself off after 2 minutes. It can easily be turned on again
without disturbing the operating mode of the analyzer by pressing the ON key.

OPERATION
Run Mode
The RUN mode is the normal operating mode of the analyzer and is entered upon power-up. When the
Run mode is entered, the analyzer will begin displaying the TSS value. When running in MLSS or RASS
measurement modes (CAL1 or CAL2 modes for the Model 35L), the TSS reading takes about 15 seconds to
stabilize. The display is continuously updated with the current date, time, TSS value, and measurement
mode. In the event of an error or alarm condition the display will indicate the problem in plain English text.
The analyzer and sensor have been zero calibrated at the factory and given a default span. In most
cases, the factory default span will read reasonable values, but a span value based upon lab analysis should
be performed as soon as possible. Span calibration can be accomplished using the snapshot/span feature
described later in this manual. Separate span values for MLSS and RASS samples are available to insure
maximum accuracy throughout the plant.
Once a TSS reading is stable, the operator may log the current TSS value. Pressing the ENTER key will
display the Select Log Locale screen.
A log locale may be selected by pressing the UP and DOWN keys until the desired locale is highlighted.
Pressing the ENTER key will display a Log conformation screen.

PCExtract
When the Model 3150 is in the PC extract mode, a PC may extract the logged data. The download kit
includes a cable and an Excel spreadsheet with embedded extract function.
The InsiteIG TSSLog (version 3.0) spreadsheet is a convenient tool for extracting logged data from the
Model 3150. It is a Microsoft Excel spreadsheet with an embedded Visual Basic program (macro) capable of
reading the logged data from the Model 3150 through a serial port and sorting it into location worksheets. The
user must have Microsoft Windows 98 (2nd edition) or later versions with Microsoft Excel 97 or later versions to
use this utility.
Installation
There are 2 steps that the user must complete before using the InsiteIG TSS Log Data spreadsheet for
the first time:
1. Copying the included files to the computer’s hard drive:
•Insert the InsiteIG CD into the CDROM drive.
•After a few seconds, an installation SETUP program should run automatically.
•If the Setup program does not start automatically, click your Windows START button, then
click RUN…BROWSE. Find the “IIGSetup.exe” file on the CDROM drive and select it and
click OPEN…OK to run it.
•Follow the installation instructions on the screen.
2. Enabling the use of “macros” in Microsoft Excel. (Excel 2000 and 2002 only; Excel 97 users
may ignore this step)
•Start Excel
•Click on Tools…Macro…Security
•Choose the Medium Security option
•Click OK
Startup
You should now be ready to use the InsiteIG TSSLog30.xls spreadsheet. The file is loaded into Excel like
any other spreadsheet. The CD SETUP routine copied the file to C:\InsiteIG, but the file can be moved using
Windows Explorer if it is more convenient to the user. The file itself can be dragged to the Windows desktop
for convenience, or a shortcut to the file can be created on the desktop. To create a shortcut from Windows
Explorer, right-click on the file and choose “Create Shortcut”. A shortcut will be added to the file list. Drag this
shortcut to the desktop.
If you have adjusted MACRO security according to step 2 of the installation procedure, Excel will present a
pop-up box every time you load the InsiteIG TSSLog30 spreadsheet. The box will ask if you would like to
enable macros for this spreadsheet. You must choose ENABLE MACROS or the serial port function will not
work!

Setting COM port
On the right side of the “Main” worksheet is a box for selecting the serial port to be used for
communications with the Model 3150. Using the supplied cable, connect the Model 3150 to an available serial
port 9 pin connector on your computer. If you know the “COM” number for your computer’s connector, click
this COM number on the spreadsheet. If not, the simplest approach is to find the correct number by trial and
error. Turn on the Model 3150, press the MENU button, then choose the “PC Extract” option and press
ENTER. The Model 3150 screen should read “Waiting for request from PC…”
You are now ready to click on the spreadsheet button that reads “Click here to retrieve data from the
Model 3150”. If you have chosen the wrong COM port, you will get a communications error box on the screen
after about 5 seconds. Try choosing another COM port number in the spreadsheet, and click the “…retrieve..”
button again.
Normal Operation
Once Excel has been properly configured for using this spreadsheet, the operation should be very
intuitive. Pressing the “…Retrieve..” button causes all of the following actions to take place:
•The PC will read all stored data points (as many as 50) from the Model 3150. This action does not
erase these data points from the Model 3150 memory.
•The newly extracted data points will appear on the “Main” worksheet of the Excel file for review.
(Previously extracted data will be erased from the Main worksheet at this time. Only the currently
extracted data appears on the Main Worksheet.) Each log point contains a location name, a time
stamp, and a TSS value.
•All data will be archived by adding it to a worksheet named after the “locale” or location name given to
each data point. If a worksheet for the location does not exist, it will automatically be created. If a
data point has the same time stamp as one that has already been archived, a new entry will not be
created in the worksheet.
Note: The time stamp given to each point uses the month/day/hour/minute that was stored in the Model
3150. However the year is deduced from the PC system clock
Once the data is retrieved into the .xls file, it can be treated as any other spreadsheet data with normal
Excel copy, graphing, and computational functions available.
The .xls file should be saved after every use for continued archiving of data.

Setup Mode
This mode of operation allows the user to customize the unit to the specific operation and needs of the
facility. There are a total of nine options that may be adjusted.
Operation of the Setup MODE proceeds as follows:
First, after pressing the "MENU" key, use the “ARROW” keys to move the cursor to the setup option, then
press the “ENTER” key. A menu with four of the ten options will be displayed. The options are;
MEASURE MODE
CLEAR ALL LOGS
DEFAULT SPAN
SENSOR ZERO

SET LOG MODE
SET CLOCK
PASSCODE
Second, use the “ARROW” keys to move the cursor to the desired setup option, then press the “ENTER”
key. When the user is finished making the adjustment, press the “MENU” key to return to the previous page.
Finally, to return to the RUN MODE, press the “MENU” key until the MAIN MENU is displayed. Use the
“ARROW” keys to move the cursor to the run option, then press the “ENTER” key.
Measure Mode
The Model 3150 can operate in one of three measurement modes:
FAST – no data filtering, fast response and factory default span (useful for measuring blanket level
depths).
MLSS - normal 15 second data filtering and low range span calibration factor.
RASSS – normal 15 second data filtering and high range span calibration factor.
Note:
MLSS mode will be displayed as CAL1 mode when using Model 35L sensor.
RASSS mode will be displayed as CAL2 mode when using Model 35L sensor.

The passcode is a three digit security number which will disallow unauthorized access to the setup mode.
To change the passcode, press UP or DOWN until the desired code is displayed, and then press ENTER.
The value of “000” will disable the passcode function.

Sensor Calibration
To do a complete calibration, three steps are required. The analyzer must first be zeroed in clean water.
Secondly, a sample/snapshot reading should be taken in a normal representative water sample. The sample
water can then be given a laboratory analysis, and the span of the analyzer can be adjusted by recalling the
snapshot and matching the reading to the analysis. As long as the lenses are kept clean, frequent
recalibration should not be necessary. Every six months should be more than adequate for a complete
calibration. The Model 3150 allows the operator to save both a low range (MLSS/CAL1) and a high range
(RASSS/CAL2) span calibration. The Model 3150 will use the MLSS/CAL1 or RASSS/CAL2 span calibrations
as selected by the measure mode.
Any optically based device for measuring suspended solids should only be span calibrated against a
typical sample of the actual process water being measured. Synthetic laboratory standards will add
unnecessary inaccuracies to the system and are not recommended. The Model 3150 utilizes its
microprocessor memory in a unique way to make span calibration as easy and accurate as possible. This
calibration is performed as a two step process. First, the SNAPSHOT function of the analyzer is used to store
actual process conditions to the instrument’s memory. Later, when standard laboratory analysis results are
available for those previous conditions, the analyzer’s SPAN function will recall the stored value and allow the
user to adjust the span value accordingly.
The range of operation of the Model 35 sensor is 0-30,000 mg/l total suspended solids. Within this range,
accuracy and repeatability are only specified over a range of +/- 50% of the user’s point of calibration.
Accuracy will be +/- 5% of the current reading or +/- 100 mg/l, whichever is greater. Repeatability will be +/-
1% of the current reading or +/- 20 mg/l, whichever is greater.
The range of operation of the Model 35L sensor is 0-1500 mg/l total suspended solids. Within this range,
accuracy and repeatability are only specified over a range of +/- 50% of the user’s point of calibration.
Accuracy will be +/- 5% of the current reading or +/- 2 mg/l, whichever is greater. Repeatability will be +/- 1%
of the current reading or +/- 2 mg/l, whichever is greater.
Sensor Zero
Each TSS sensor will have a unique zero reference. This calibration mode will calculate and store the
zero reference for the current sensor.
Select the "Sensor Zero" option from the calibrate menu using the up and down arrow keys. Press the
"ENTER" key. Submerge the sensor in clean water. It is important that the water used to zero the sensor be
clean. At the very least use potable water for this, and distilled water is even better. Do not use plant process
water of any type. With the sensor submerged in clean water, wait about 15 minutes and then press
"ENTER". The analyzer will take about 15 seconds to zero. The display will return to the calibrate menu
automatically when it is finished. Press the "MENU" key to exit or use the up and down arrow keys to select
another calibration mode.
Snapshot
This calibration mode simply stores a reading in a special memory location within the analyzer. The
operator should take a physical sample of the process water from the same location so that it can be analyzed
using standard laboratory techniques to determine suspended solids concentration. When the lab analysis is
complete, this stored reading can be recalled in the SPAN mode. Matching the stored reading to the lab
analysis adjusts the span of the analyzer.

With the sensor submerged in the process to be measured and stable, select the "Snapshot" option from
the calibrate menu using the up and down arrow keys. Press the "ENTER" key. Pressing the "ENTER" key
again will cause the analyzer to take a snapshot of the conditions. The analyzer will take about 15 seconds to
obtain a sample value. The display will return to the calibrate menu automatically when it is finished. At this
point, the calibration of the analyzer has NOT been altered; only the conditions of the process water have
been stored in memory for future use. Press the "MENU" key to exit or use the up and down arrow keys to
select another calibration function.
Sensor Span
This step is performed when an accurate laboratory value has been obtained from the sample previously
taken during the Snapshot procedure.
Select the "Sensor Span" option from the calibrate menu using the up and down arrow keys and press the
"ENTER" key. The value that was previously saved snapshot will be displayed. Use the up and down arrow
keys to adjust the analyzer reading to the value of the laboratory analysis. Press the "ENTER" key when done.
The system is now calibrated and ready for normal operation. Press the "MENU" key to exit or use the up
and down arrow keys to select another calibration mode.
Default Span
This calibration mode will replace the current span calibration value (MLSS or RASSS) with the factory
default value. This may be useful when using the system in a new application. If the analyzer has been
properly zeroed in clean water, the analyzer will read values that are typical for an average waste treatment
plant. No absolute accuracy is guaranteed after this procedure, but the numbers will, in the least, be useful for
observing trends in the suspended solids concentration over time.
Select the "Default Span" option from the calibrate menu using the up and down arrow keys and press the
"ENTER" key. Pressing the "ENTER" key again will cause the analyzer to use the factory default span
calibration value. Press the "MENU" key to exit or use the up and down arrow keys to select another
calibration mode.
Sensor Curve
This option allows the user to select between the standard TSS curve or a special TSS curve. The
standard curve was modeled after typical waste treatment plants and should be used for most applications. In
applications that has a very dark sludge or nonstandard characteristics, the special TSS curve may be used.
When the special TSS curve is selected, the user will be prompted to enter a brown factor and a black factor.
These factors are calculated by the factory based on field data collected at the site.

Autolog Mode
The Autolog Mode will cause the Model 3100 to automatically log up to 50 entries at the selected interval.
After 50 entries are logged the Model 3100 will turn off.
Note: The Model 3100 should be fully charged prior to the start of an auto log session, because it must
remain on for the entire auto log session.
To select the AUTOLOG mode select Log Mode from the Setup menu, then select auto.
Note: When auto log mode is selected, all previous logged entries will be erased.
The Model 3100 will prompt for the log interval and then the locale.

ERRORMESSAGES
During operation, the Model 3150 analyzer may determine that an error condition exists. If this happens,
the display will contain an error message. The 3 possible error messages are as follows:
**Sensor not Responding**
This error message indicates that the analyzer is not receiving any data from the sensor. This would most
likely be caused by a faulty sensor cable or possibly a faulty sensor or analyzer electronics.
**Zero Sensor**
The analyzer is indicating that a zero cal operation is required for proper operation. This can occur if the
sensor was not properly zeroed and the current sensor reading is 5% above (negative) the pervious stored
zero value.
*Ambient Error*
This error message will be displayed if the sensor is exposed to too much ambient light (exposed to direct
sunlight). Or the sensor LED is faulty.

MAINTENANCE
The analyzer does not require any periodic maintenance. The sensor must be kept clean for accurate
readings.
