. You can do this yourself using a
humidity reference (for example, the Vaisala Humidity
Calibrator HMK15), or send the probe to a Vaisala Service
Center for calibration
For instructions on setting a calibration reminder message
(3-24 month interval), see Reminder on page 34.
If the calibration shows that the measurement accuracy is
no longer within specification, the probe must be adjusted.
If accuracy cannot be restored with adjustment, the probe
must be replaced. All probes that are ordered from Vaisala
are delivered calibrated. See section Accessories and Parts
on page 53.
If you think the meter is not measuring humidity
or temperature correctly, calibration and
adjustment is not the first thing to do. Try the
following first:
- Make sure nothing is interfering with the
measurement: heat sources, temperature
differences, or condensation.
- Check that there is no moisture on the
probe. If the sensor has become wet, you
must allow it to dry before you can measure.
- Always wait for the measurement to
stabilize.
