Battery – B30A/B/X/Z only Check battery voltage. Should be 3.6V DC. Replace if low or bad.
Loop Power
OTE:N Not available on B30S
Check 4-20 mA input. Voltage must be within the minimum and maximum
supply voltage and capable of supplying enough current to run the display.
The input voltage is checked “across” or in parallel with the 4-20 mA terminals.
and current is checked with the ammeter in series with the 4-20 mA output.
Solar Place meter with solar cell exposed to a strong light source for 24 hours.
No Rate or Total Displayed
Check connection from meter pick-up to display input terminals.
Check turbine meter rotor for debris. Rotor should spin freely.
Check programming of flow monitor.
Flow Rate Display Interprets Reading
Constantly
This is usually an indication of external noise. Keep all AC wires separate from
DC wires.
Check for large motors close to the meter pick-up.
Check for radio antenna in close proximity.
Try disconnecting the pick-up from the monitor pig tail. This should stop the
noise.
Flow Rate Indicator Bounces
This usually indicates a weak signal. Replace pick-up and/or check
all connections.
Examine K factor.
