Frequently Asked Questions

Q1: How many times does the BT2000 smoke meter needs to be calibrated?
A1: Once a year

Q2: Where do I send my BT2000 smoke meter for calibration?
A2: Send the BT2000 smoke meter to 1232 E Pomona St Santa Ana, CA 92707

Q3: How much does it cost and how long will it take to do the calibration?
A3: for next business day: standard charge
      for walk-in, 2-4 hours: (standard charge+$50, by appointment only)
Note: All meters need to be calibrated per manufacture recommendations, either by calibrating the meter or re-measuring the calibration filters.

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. only the BT Wireless meter can test these vehicles using one person.

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: How to read the Old Calibration sticker?
A6: The following is an example of sensor calibration label "CAL, YOK - 101119". In this label example, the meter calibration would be good till Nov 19, 2010. The date code is YYMMDD (first year, second month, and then date).   New calibration labels now standard date format and  are easy to read.  The calibration expiration is printed on every smoke test.

Q7: BT2000 Wireless sensor status light is amber what does the mean?
A7: This typical means that the sensor battery is low. Either recharge the battery or replace with fully charged battery.

Q8: How does ambient conditions effect SAE J1667 smoke results?
A8: 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).
