7500 Smoke Meter Support
PROBLEM:

What is the proper procedure for powering on the 7500 meter ?

SOLUTION:

When powering on the 7500 system, start with the laptop. Power on the laptop, and wait for the computer to boot until you see the WagerDCU icon. Next, connect all sensors to the DCU. Next, connect the USB-Serial adapter to the computer. Now, power on the DCU and hit the reset button. Wait 10 seconds, and then doubleclick the WagerDCU icon.

PROBLEM:

I have loaded my 7500 software onto a new laptop, and I am unable to calibrate my system.

SOLUTION:

Typically, this error is caused due to an incorrect setting in the system configuration section of the program.
You must match the com port setting shown in the program to the physical com port number that is listed in the
device manager, ports (com & lpt) section.
If your configuration port setting does not match the actual port number in the device manager, then your
system will not function.

PROBLEM:

I am not able to calibrate my system, and I am seeing zero’s on my weather conditions.

SOLUTION:

Back out of all the screens and close out the Wager software.

Check all of your connections, and power off then power on the dcu. Then press reset the DCU.

Wait 10 seconds and then reenter the program and try operating the system again. This will clear up about 90% of your problems but if you still have issues with calibration or weather conditions, contact technical support.

PROBLEM:

My RPM sensor reading is 2 – 3 times higher than it should be. 

SOLUTION:

Start off by painting the damper black and ensure there is only one piece of reflective tape. The reflective tape has two surfaces same as a peak of a mountain so if you are looking straight down at the mountain top, you can see both the front and back sides of the mountain. The RPM sensor needs to be placed at a 45 degree angle to the damper. This will allow for only seeing one side of the mountain or tape for a proper reading.

PROBLEM:

I am getting an error message stating that my “weather conditions exceed specifications” What does that mean ?

SOLUTION:

Your meter is programmed to run from temperature ranges from 35 degrees to 95 degrees Fahrenheit.  In order to run a valid test, the temperature reading must be within this range, and the temperature must also be above the dew point. If it is not, moisture may affect the readings and the test is considered invalid.

PROBLEM:

Why is my ambient correction saying disabled ?

SOLUTION:

While you will always see weather conditions reported from our built-in weather station, the ambient correction feature is either enabled or disabled depending on what state you are testing in and that state’s requirements.

PROBLEM:

What exactly is “zero drift” and how does that affect my test results ?

SOLUTION:

“Zero Drift” refers to the amount of soot or build-up on your lens set. When the system first calibrates, the meter checks and references your “zero” . It then stores that value. After your testing, the meter then rechecks the “zero” value, and stores that value. It then compares both values and determines the meter is returning to “zero”. If it does not, that means the lenses have accumulated soot, and the test is invalid.

 
It is important that the sensor head be removed from the stack both with the initial calibration, and before taking your final “zero” check. Even with the engine off, hot gases are still present, and can affect your final reading.

PROBLEM:

I am having problems with my filter calibration.

SOLUTION:

If during filter verification test, the system fails calibration immediately, then there is a communication error and contact customer support.

If during filter verification test, the system draws a line and then fails, it means that the measured filter value is different than what the system is expecting. If your filter is reading higher than expected, then most likely your filter is dirty. Clean and retest. If your filter reading is lower than expected, then the filter most likely degraded and needs to be either recertified or replaced.
