Figure 9 Pyranometer CMP6, Arrow Points to Drying Cartridge
Calibrate CMP every 2 years and change the silica gel desiccant. When changing the
desiccant in the drying cartridge (indicated with an arrow in the preceding figure), perform
the following checks:
• Make sure the surfaces of the pyranometer and the drying cartridge that touch the
rubber O-ring are clean. Corrosion, dirt, and water can damage the sensor.
• The rubber O-ring is coated with silicon grease to improve the seal. If the rubber O-ring
looks dry, apply grease or Vaseline to it.
O-ring type: 24 × 3.0 NBR (nitrite rubber).
• Check that the drying cartridge is tightly threaded into the sensor body.
