The lamp will take a maximum of 15 seconds to illuminate, after which the sensor will be stable.

After periods of storage or non-usage the MiniPID 2 may be susceptible to baseline settlement issues as the light from the lamp can generate an ion current when impacting the electrodes within the detection volume. In such an event, it is recommended that the MiniPID 2 sensor is left powered in a clean air environment for an hour or two.
