Page 17: Replacing Batteries
REPLACING THE BATTERIES This meter has been designed for use with both alkaline and rechargeable Nickel Metal Hydride (NiMH) batteries . No other types are recommended . The analyzer is supplied with 4 “AA” size alkaline batteries . These should be installed into the instrument as shown in the diagram indicated on the back of the unit . -
Page 18: Other Important Factors Related To Combustion
. As an example you would measure the CO2 level and the stack tempera- ture and then reference a slide scale that would give you the relative efficiency number . UEi’s electronic combustion analyzers perform the measurements on a continuous basis, and can calculate the efficiency as adjustments are being made . -
