Troubleshooting
“I see no current data.”
Check the sensor cable’s RJ connectors to make sure they are firmly plugged into the
correct receptacle.
If you have placed the Sensor Transmitter into Test Mode, make sure you have turned
off DIP switch #4.
Check the battery and replace if necessary.
Bring the receiver closer to verify that the transmitter is actually transmitting.
Use the Sensor Transmitter’s Test Mode to further investigate the problem.
Test Mode
DIP switch #4 on the SIM (see illustration on page 3) is the TEST DIP switch. Switch it
to the ON position using a ball-point pen or paper clip. This puts the transmitter in Test
Mode
.
An LED indicator light, located above and to the right of the battery
compartment, will flash each time the transmitter broadcasts a signal, which should be
every 2.5 seconds.
If the LED flashes only once and then remains dark, there is a problem with the Sensor
Transmitter. See “See “Contacting Davis Instruments” on page 10.
If the LED flashes repeatedly but your receiver isn’t picking up a signal anywhere in the
room, it could be related to one of the following causes:
1. The DIP switches were not correctly set on the Sensor Transmitter. See “Set the
Transmitter ID” on page 3.
2. The ID was not correctly set on the receiver.
3. Reception is being disrupted by RF (radio frequency) interference. Interference has to
be very strong to prevent the console from receiving a signal while in the same room
as the anemometer transmitter!
4. There is a problem with the receiver. See “Contacting Davis Instruments” on page 10.
Note: Remember
to
turn the Test DIP switch OFF
when you’re finished testing wireless transmission.
If it is left ON, the blinking LED will reduce battery life significantly.
“Readings aren’t what I expected them to be.”
Be very careful. Comparing to measurements from TV, radio, newspapers, or a
neighbor is NOT a valid method of verifying your readings. Davis Instruments
sensors are carefully tested at the factory. If you have questions, contact Technical
Support.
