Carry Out Gas Analysis - Ecom EN3 Operating Instructions Manual

3. Carry out gas analysis

If the calibration has been successfully completed and all previous queries have been
answered, the instrument is ready for operation.
Hint
The following minimum times must be observed in order to obtain correct
measured values:
- 1 minute for fresh air calibration of the sensors
- 2 minutes for stable measured values at the instrument
Hint
To obtain accurate measurement values it's important to re-calibrate the
instrument after each measurement (at the latest after one hour)!
- Switch off the instrument and wait for the switch off phase
- Switch on the device and refer to chapter "2. Measurement Preparations".
The current measured values of the active sensors are displayed in the measurement menu.
In addition, various measuring procedures are available:
