Avoid Condensation and Rain
If the humidity sensor element becomes wet, the meter
cannot measure until the sensor is dry again. Avoid rain
and conditions where condensation can form on the
sensor.
Do not replace the transport protection cap if the probe
or the cap is wet, since it will prevent the probe from
drying.
Do not touch the sensor or blow on it to dry it
out.
Calibrate the Meter Regularly
It is recommended that you calibrate the probe
once a
year
, or if you have any reason to believe it is no longer
within its accuracy specification. See section Calibration
on page 47.
You can set a reminder for calibration at preferred
calibration intervals (3, 6, 12 or 24 months). See section
Reminder on page 34.
