1.9. Sensor reconditioning

Over time, the internal sensor may become compromised as a result of pollutants,

chemical vapours or other environmental conditions. This can lead to inaccurate

readings. To recondition the internal sensors, use following procedure:

• Heat the datalogger to +80°C (+176°F), humidity < 5% for 36 hours.

• Keep the datalogger at+20~+30°C (+70~+90°F), humidity >74% for 48 hours
