(measure voltage at “+9V” relative to
“Gnd”). Check transmitter battery
connections.
Mismatched
frequencies Double check jumper settings on
transmitter. Verify receiver is set on
tra
nsmitter’s frequency by rotating RF
channel knob on rear panel of receiver
through all 8 positions.
Incomplete RF
transmission path Relocate receiving antenna to optimize
transmission path from transmitter.
Double check antenna cable
connections.
Symptom: Unstable data, wandering zero
Problem/Cause
Solution/Corrective Action
Low battery voltage
at transmitter
Check to see if red “Low TX Power” light
is blinking on RD9000 front panel.
Measure battery voltage under load (i.e.
connected to transmitter). Replace if
battery voltage is less than 7.5 volts.
Faulty sensor wiring Check integrity of sensor connections.
Shield sensor leads and move away
from antenna.
Faulty sensor. Temporarily connect BS900 bridge
