18 CALIBRATION AND MAINTENANCE FOR MINIMET WEATHER STATIONS
1. DATAHOG2 DATALOGGER
The logger should never be used outdoors without either a sensor plug or blanking dustcap fitted to
any of its sockets. Periodic check that all are in place is advisable.
An annual check / replacement of the internal batteries (if fitted) should be made, and the ‘O’ ring
lid seal replaced.
The logger itself should be periodically checked that the electronics is recording accurately. This can
be done by Skye or by applying known voltages, currents or digital pulses into the logger inputs
and checking the logger’s measurements.
2. RELATIVE HUMIDITY SENSOR
Theses sensors are recommended to be calibrated annually.
The sensor (or DataHog2 logger with integral sensors) can be returned to Skye or the RH
recalibration kit (SKH 1092 or 1093) provides equipment for the user to make their own recalibrations
using the saturated salt solution technique.
The radiation screen and mounting should be kept clean to ensure good air flow over the sensor tip.
3. AIR TEMPERATURE
Theses sensors are recommended to be calibrated annually.
Sensors can be returned to Skye or can be checked by a direct comparison against a reference
thermometer in a controlled environment.
The radiation screen and mounting should be kept clean to ensure good air flow over the sensor tip.
4. SOLAR RADIATION, UV AND LIGHT SENSORS
The light collecting surface of these sensors should be kept clean by gently wiping with a damp
cloth. Do not use solvents. Care must be taken not to scratch this surface.
These sensors require recalibration every 2 years, return to Skye is recommended for accurate
calibration. Pyranometer sensors can be calibrated by a direct comparison against a Reference
Pyranometer under clear sky conditions. Other sensors require calibration using an optical bench
