0 ÷ 4000 mg O
0 ÷ 999 mg O
0 ÷ 600 mg O
0 ÷ 250 mg O
0 ÷ 90 mg O
The scale is related to the expected value. The possibility of measuring diluted samples extends the range.
Results are shown as mg O

3.6 Analysis duration and sampling time
Wireless mode
With RESPIROMETRIC Sensor an analysis can last from 5 to
120 days. The sampling time can be selected depending.
on the desired duration of the analysis, from 1 h to 2 days

AL1 Calibration error. Restart the analysis. If the problem persists contact the service.
AL2 Analysis start denied. Check on RESPIROSoft™.
AL3 Max. sensors q.ty reached. 50 analyses are already in progress. Wait the end.
AL4 One parameter or more are wrong
AL5 No PC response. Check the distance between the RESPIROMETRIC Sensor and the Wireless DataBox™.
AL6 The analysis is stopped from the PC
AL7 Unknown command result
AL8 Data sending failed. Restart the analysis. If the problem persists contact the service.
AL9 No PC response. Check if the RESPIROSoft™ is active.
AL10 No automatic measure is done
AL11 Wireless DataBox™ not found. Check if the Wireless DataBox™ is connected.
Wireless DataBox™ connection isn't strong enough
AL12
AL13 Analysis start is denied due to low battery level
bAt Low battery (wireless mode OFF). Remove the batteries with the fingers and replace them with new ones paying
attention to the polarity indicated inside the instrument.
Err Calibration error (wireless mode OFF).
--- The measured value overcomes the maximum value of the chosen scale.
4. Maintenance
RESPIROMETRIC Sensor warns about the required change of batteries when the unit is resetted and the charge is lower
than a minimum threshold. Use a coin lever in the rear part of RESPIROMETRIC Sensor and open it. Batteries are removed
using the fingers. Introduce two fresh batteries at the same time paying attention to the polarity. Battery replacement deletes
any stored value.
