Operation
4.3 Combustion Test
IMPORTANT! Large rapid changes in the temperature of
the analyzer can affect its accuracy. This is important to
know if the analyzer is stored in a cold place (such as an
unheated vehicle in the winter) and then taken into a warm
furnace area. For the most accurate test results, allow the
analyzer to warm up to room temperature before use (about
10 minutes).
4.3.1 Analyzer Turn On and Warm Up
IMPORTANT! Be sure the probe is at room temperature
before performing the following steps.
1. Make sure that the analyzer is properly set up per Section 3.0.
2. Place probe in an area of fresh, ambient air; then press the analyzer’s
key.
3. Wait for the analyzer to countdown through its 60 second warmup
period; then perform one of the following:
• If no errors were detected during warmup, the Combustion
Test Screen will be displayed. Skip Step 4, and go to Section 4.3.2.
• If an error was detected during warmup, proceed with Step 4.
4. If one or more errors were detected by the microprocessor during
warmup, these errors will be displayed at the bottom of the Sensor
Status Screen. Address any problems now per Section 7.2; then repeat
this procedure starting with Step 1.
NOTE: If the error detected is not critical to your test, the
instrument can still perform any test not using the function
disabled by the error.
