Can the internal pump operate continuously?

Yes. The pump has a rated lifetime of 5,000 hours (7 months).

Can I use a different program than Hyper-terminal to collect the data?

Yes. A program called Tera-Term is available at the following website: http://hp.vector.co.jp/authors/VA002416/teraterm.html The Tera-Term program is preferred since Hyper-terminal only has a 500 line buffer limit.

Does elevation affect the accuracy of the ozone analyzer?

No. The accuracy of the analyzer will only vary 1-2 PPB for any elevation of 7,000-ft or less.

Is the ozone analyzer sensitive to other gases?

Yes. It is also sensitive to organics but low levels will not contribute significantly to interference. The general rule is that if you can smell the organic, then it may cause slight interference with the reading. Mild odors are typically not an issue. Chemicals like those commonly found in labs do not cause interference with the ozone analyzer.

How often does this monitor require calibration?

The manufacturer recommends a yearly calibration. The readings of all ozone monitors will start to stray over time and need to be corrected when possible.

Will I get a tracking number when my item ships?

For customers who chose UPS: a tracking number is automatically sent via e-mail before the order leaves our warehouse.

For customers who chose FedEx: a tracking number is usually available if requested by either e-mail or phone.

For customers who chose USPS: tracking numbers are only created by USPS for select services, such as insured packages. We will be happy to provide available tracking information if requested.

How often should the unit be re-zeroed?

Upon receipt of the UV-106, you should re-zero the unit so it is set properly for your location. The electronic zero of the instrument may be measured by attaching an ozone destruction cartridge to the air inlet for a period of 5-10 minutes.

For an accurate measurement, the instrument must have been turned on long enough for the internal temperature to stabilize. The observed offset, which can amount to ± a few ppb, can be corrected for by changing this calibration parameter from the front panel, as described below.

Because of noise and/or an inherent offset, some measured values will be below zero at very low ozone mixing ratios or while zeroing the instrument with an external scrubber. Also, the instrument zero may drift by a few ppb over time. For this reason, frequent zeroing of the instrument using an external ozone scrubber to determine the offset is recommended. If the instrument reads an average of 3 ppb with the external scrubber in place, the value of Z should be set to –3.

What type of serial (RS-232) cable do I need to connect my UV Analyzer to my computer's serial port?

For a serial connection, you will need a straight-through cable with female-to-female DB-9 connectors.
