1. Connect the probe and water trap to the unit. Make sure the probe tip is at
room temperature.
2. Turn the analyzer on. Make sure that the “battery low” message does not
appear on the display.
3. Make sure that the analyzer pump is on. (Always zero the instrument
with the pump on, for flue stack measurements!)
4. Press the ZERO button. Press ENTER to confirm. Wait for the
countdown to end.
5. If no error messages appear at the end of the countdown proceed with
your measurements.
B. SPAN CALIBRATION
You must always span calibrate the instrument every time you replace a sensor. At
a minimum, once every 3-4 months you should perform a span calibration of the
instrument. For greater accuracy you should check the calibration of the instrument
before and after each emissions test. The parameters that require a span calibration
are, depending on the available options: carbon monoxide, nitric oxide, nitrogen
dioxide, sulfur dioxide, combustibles and draft.
You can carry out all span calibrations in sequence or just one, if you wish.
You can use your own span gas, or if you need to calibrate the ENERAC in the
field, you can use the convenient gas calibration kit supplied by ENERAC.
