Frequently Asked Questions

Q1: How many times does the BT2000 smoke meter needs to be calibrated?
A1: Once a year,  latest version of software will start to remind user approximately one month before calibration is due.

Q2: Where do I send my BT2000 smoke meter for calibration and what do I send?
A2: Send the BT2000 smoke meter (meter, sensor, and printer in compact carrying case) to 1232 E Pomona St Santa Ana, CA 92707 with fill out repair service form (RMA).

Q3: How much does it cost and how long will it take to do the calibration?
A3: Typically done by next business day: standard charge (approx $200)
for walk-in, 2-3 hours: (standard charge + rush, by appointment only)


Note: All meters need to be calibrated per manufacture recommendations, either by calibrating the meter or re-measuring the calibration filters (with proof filter is calibrated).

Q4: How many people are needed to use your device and conduct the test on a vehicle?
A4: Typically one person is required to conduct smoke tests on regular cab trucks RVs, buses, box trucks and etc with few exceptions, if the distance between the tail pipe and the steering wheel is greater than 23 ft. and less than 100 ft.

Q5: Does the meter have a GPS?
A5: The meter does not have a built in GPS. Latitude, Longitude, and Altitude can be entered manually in test site menu.

Q6: BT2000 Wireless sensor status light is amber what does the mean?
A6: This typical means that the sensor battery is low. Either recharge the battery or replace with fully charged battery.

Q7: How does ambient conditions effect SAE J1667 smoke results?
A7: If smoke meter ambient correction is turn off, then smoke results are not adjusted. If ambient correction are turn on, then then the smoke results are adjusted using the SAE J1667 Appendix B reference dry air density. The smoke meter has built in humidity, temperature, and pressure sensor to calculate ambient correction.


Note a few artifacts of the ambient correction equation: Extreme humidity variation has a minor effect on the resulting smoke adjustment. Extreme temperature has a bigger effect on smoke adjustment. Extreme pressure/altitude changes has a big effect on smoke adjustment.

Note: In extreme ambient condition, the ambient equations in SAE J1667 Appendix B may not be accurate (as stated in the SAE J1667).

Q8: In California, if the vehicle is subject to Periodic Smoke Inspection Program (PSIP) and/or Heavy-Duty Vehicle Inspection Program (HDVIP), when do they need to start being smoke opacity tested?
A8: In California, those vehicles 2011 and older needs to be smoke opacity tested before the end of 2015. In California, the opacity cut point for 1991 new truck is 40% and for trucks older 1990 the opacity cut point is 55%.  If you have any questions or doubts, about when to start opacity testing your vehicles or the opacity cut points, please contact the ARB.

Q9: How do I clean the wireless sensor windows?
A9: Cleaning the wireless sensor windows is quick and simple. First, slide open the both trap doors on the top of the sensor head. Second, wipe each sensor windows with a clean dry cotton swab. Third, slide close both trap doors on the top of the sensor head. Do not use any liquids or alcohols or window cleaner on the cotton swabs or sensor windows.

Q10: Can I test my own vehicles in California?
A10: Short answer is yes, but it is strongly suggested that you be CCDET trained at a CCDET College. If you plan to smoke test trucks own by others, it is almost required to be CCDET trained.

Q11: How do I know when the Meter or Sensor battery is fully charged?
A11: When charging the meter or sensor the Green LED will blink when the battery is fully charged. However, it is best to leave the adaptor plug into the Meter or Sensor for one to two hours after the green LED starts to blink. If the meter or sensor is not going to be used for a long period of time, it is good to periodically charge the meter and sensor.
