If there are high chemical concentrations present in the measurement environment, some sensor drift can occur. If you experience this kind of drift, it can be necessary to perform the sensor purge more often. The purge interval can be varied between 1 ... 48 hours. However, note that frequent sensor purges reduce battery operation time.
To change the automatic sensor purge interval:
- Open the menu by pressing Open.
- Select Settings and press .
- Select Measurement settings and press .
- Select Purge interval and press Set.
- Set the desired purge interval with the arrow buttons. Press Ok to confirm.
- To return to the basic display, press Exit.
