Page 3: Safety
This analyzer extracts combustion gases that may be toxic in relatively low concentrations. These gases are exhausted from the back of the instrument. This instrument must only be used in well-ventilated locations.It must only be used by trained and competent persons after due consideration of all the potential hazards.

Page 5: General Maintenance
eNeral aiNteNaNCe • Check calibration of your instrument annually to ensure it meets original performance specifications • Keep your instrument dry. If it gets wet, wipe dry immediately. Liquids can degrade electronic circuits • Whenever practical, keep the instrument away from dust and dirt that can cause premature wear • Although your instrument is built to withstand the rigors of daily use, it can be damaged by severe impacts. Use reasonable caution when using and storing the meter. eriodiC erviCe WARNING! Repair and service of this instrument is to be performed by qualified personnel only. Improper repair or service could result in physical degradation of the instrument. This could alter the protection from per- sonal injury this meter provides to the operator. Perform only those maintenance tasks that you are qualified to NNual alibratioN... -
Page 6: Battery Replacement
This product has been tested for compliance with the following generic standards: EN 50081-1, EN 50082-1 and is certified to be compliant. The European Council Directive 89/336/EEC requires that electronic equipment does not generate elec- tromagnetic disturbances that exceed defined levels and has an adequate level of immunity to enable it to be operated as intended. Since there are many electrical products in use that pre-date this Directive and may emit electromagnetic radiation in excess of the standards defined in the Directive there may be occasions where it would be appro- priate to check the analyzer prior to use. The following procedure should be adopted. • Go through the normal start up sequence in the location where the equipment is to be used • Switch on all localized electrical equipment that might be capable of causing interference • Check that all readings are as expected (a level of disturbance in the readings is acceptable) • If not, adjust the position of the instrument to minimize interference or switch off, if possible, the offending equipment for the duration of the test At the time of writing this manual (August 2011), UEi is not aware of any field based situation where such interference has ever occurred and this advice is only given to satisfy the requirements of the Directive. -
Page 7: Why Test With The C20
• The UEi C20 combustion set-up meter gives a quick, continuous readout of the combustion process. Readings change in real-time as adjustments are made to help zero in on the proper setting. Compare this to spot tests or other methods, and you will see your productivity rise. • Proper testing will help you provide the proper service or equipment replacement recommendations, and have the data to support this. Sales will increase because you are no longer guessing, and the... -
