TROUBLESHOOTING
Problem:
No Reading
• Check that you have the correct supply
voltage at the power terminal blocks.
• Check that wiring configurations and all
DIP switch settings are as in Figures #1,
#2 and #7.
• Verify that the terminal screws are all
connected tightly and that all of the wires
are firmly in place.
Erratic Readings
• Verify that all of the wires are terminated
properly.
• Make sure that there is no condensation
on the board.
• Check that the input power is clean. In
areas of high RF interference or noise,
shielded cable may be necessary to
stabilize signal.
Inaccurate Readings
• If you suspect that the transmitter is not
reading within the specified tolerance,
please contact the factory for further
assistance.
