MENU Using the Menu The Menu position on the Rotary Dial allows for the customization of the default settings for the analyzer as per the user’s requirements. Navigation through the Menu system is via the dedicated user’s interface buttons (Up, Down, Enter). Menu Option to edit As you navigate up or down through the Menu, the items will scroll accordingly, eventually back to the beginning.
STORED LOGS MEMORY The C161 utilizes a shared memory system much like a computer hard drive. The different Log types are stored sequentially until the shared memory area is full. This means the log types are not restricted to a smaller number of memory locations as the full memory capacity is available as required for Logs of any type.
Viewing Stored Logs Once the view has been selected from the Logs Menu the following screen will be displayed: List of available Logs (Navigation and selection via the buttons). Log View Menu Options View stored Combustion Logs (Option will appear if Logs are available). View stored Auxiliary Logs (Option will appear if Logs are available).
Log Navigation Menu Options Print the currently selected Log Navigate to the next available Log of the selected type (Option will only appear if there is more than one Log). Navigate to the previously selected Log of the selected type (Option will only appear if there is more than one Log).
HEAT EXCHANGER TEST NOTE: Test results; O2, CO and Excess Air will show on the printout. There are many methods to test heat exchanger integrity. One of these is to observe the Excess Air, O2 and CO readings both before and after the blower turns on.
To print, simply press and release the PRINT BUTTON. Printing can be aborted by pressing the PRINT BUTTON again. UEi Infrared Printer Make sure the printer is switched on, ready to accept data and its infrared receiver is in line with the analyzer’s infrared emitter (on top...

POWERING OFF When you power off the C161, there is a 10 second purge. Make sure you do not exceed the analyzer’s operating specifications. In particular: • Do not exceed the flue probes maximum temperature (1112˚F) • Do not exceed the analyzer’s internal temperature range •...
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 and will void warranty. The analyzer is supplied with 3 (AA) size NiMH rechargeable batteries. These should be installed into the instrument.
Same Day Service: All qualifying analyzers received for recertification through UEi Service+ are returned on the same business day .* Free Shipping: UEi Service+ offers free shipping both to and from our service center . When customers book their recertification, they receive a prepaid UPS Ground shipping label .
UEi’s electronic combustion analyzers perform the measurements on a continuous basis, and can calculate the efficiency as adjustments are being made. Combine this with a printout and you are able to provide a before and after comparison of the combustion equipment in relatively little time as part of normal servicing.
Any implied warranties, including but not limited to implied warranties of merchantability and fitness for a particular purpose, are limited to the express warranty.
