CAUTION: Although the analyzer itself is not damaged by extremely cold
temperatures, the electrochemical sensors may sustain damage. The O
2
sensor’s
electrolyte will freeze at approximately -13ºF (-25ºC), and the other sensors at
approximately -94ºF (-70ºC). If the analyzer is exposed to extremely cold conditions,
it is strongly suggested that the sensor housings be examined for hairline cracks.
Be aware that a leaking sensor can cause chemical burns to the skin and possibly
damage the surrounding PCB assemblies.

3.1 Setup
Properly preparing the analyzer is critical to accurate analysis and safe operation. Be
sure to read the following instructions prior to use of this instrument.
3.1.1 Operation Tips
Allow Analyzer to Warm-up Slowly
When an analyzer is brought in from a cold vehicle, allow it to warm-up slowly to minimize
condensation. Temperatures below freezing will not damage the analyzer.
