Troubleshooting guide

Manufacture of these parts ended several years ago and stocks at Davis and at dealers have long since
been exhausted. Note that it is still possible to replace the temp/hum sensor with a simple temperature
sensor, which is still available – obviously the humidity and dew point readings will be lost, but it may be a
way of prolonging the life of an elderly system.
Other standard sensors (except for the pressure sensor, which is on the console main board) are still readily
available. The 6410 VP2 anemometer is fully compatible with VP1 and older stations. A defective rain gauge
can be repaired either by replacing the reed switch or by substituting a separate 7852 standalone rain
gauge (or its new equivalent, the 7857 pole-mounting rain gauge). And the VP2 6450 solar and 6490UV
sensors are both fully compatible with the VP1 station.
Replacement transmitter parts for VP1 and older stations
Replacement transmitter boards may still be available in principle, but they will be relatively costly and
dealers may be reluctant to source them in practice. Few dealers will maintain stocks nowadays because of
absolutely minimal demand and sourcing a replacement board up the supply chain may be a long and
fraught process.
Console repairs for VP1 and older stations
The situation here is similar to that for replacement transmitter parts – it’s not impossible that parts may be
available or that repairs could be done, but the uncertainty and cost and time taken in sourcing parts might
make attempting the repair seriously unattractive. If such a repair is needed then it’s likely that the
conclusion would be that the station is beyond practical or economic repair.
