Fyrite Pro Quick Reference Guide Operating Tips • When an analyzer is brought in from a cold vehicle, let it warm up slowly to minimize condensation. Temperatures below freezing will not damage the analyzer; however, bringing a cold analyzer into a warm, humid environment may cause condensate to form inside the case. • If the CO channel (Model 100/105/120/125) is set up for Auto Zero (refer to Section 3.5.3 in Instruction 0024-9395), ensure that the analyzer is sampling fresh air when turned ON.
Fyrite Pro Quick Reference Guide CO Channel Zero (Model 100/105/120/125) If the CO channel is set up for manual zero (refer to Section 3.5.3 in Instruction 24-9395), and if the CO Screen shows a value other than zero when sampling fresh air, then zero the CO channel as follows: 1. With the analyzer turned OFF, place the unit in fresh, ambient air; then press and hold down the ENTER button. 2. Press the I/O button and release it. Observe that all LCD segments are turned ON. 3. Release the ENTER button.
Fyrite Pro Quick Reference Guide Saving Test Data in Memory (Model 105/110/120/125) Up to 10 individual sets of test data can be saved in memory as follows: Note: When memory is full, the next reading saved will overwrite the oldest reading. Note: The analyzer’s setup information is stored along with the test data. For example, temperatures stored in °C are recalled and printed in °C even if the analyzer is currently set up for °F. 1.
Fyrite Pro Quick Reference Guide 2. Press the or button until the Open Screen is displayed, and then press ENTER to open the memory locations for viewing. The number shown in the second screen represents the most recent memory location where data was stored. 3.
