Erratic Readings on Your FINCH Display
Troubleshoot Fluctuating Volume Readings
If the volume reading on your FINCH display is fluctuating unexpectedly and the values seem illogical, this could indicate a problem with your transmitter that needs attention.
Troubleshooting
Key Areas to Check
Below are some key areas to examine when encountering this situation.
- Probe Issue: Check the probe for physical damage, corrosion, or product build-up. If the probe is bent, repair or replace it. If the shorting block is missing or loose, replace or tighten it as needed. If build-up is present, clean the probe using a suitable solvent such as brake cleaner. For Dual Rod Probes, check the gap between the rods at the height where the erratic readings start to appear on the FINCH display — any product stuck on the probe needs to be cleaned with a suitable solvent.
- Transmitter and Probe Connection Issue: Check the connection between the probe and transmitter for contamination such as water, anti-seize compound, or oil. Clean all surfaces of contaminants to ensure a good mechanical connection. Refer to the installation video before putting the transmitter back onto the probe.
- Power Supply Issue: Check the power supply to the FINCH.

If Nothing Above Resolves the Issue
There is an internal issue with your transmitter, and it will need to be repaired or replaced.

Radio Interference Note
Erratic readings can also be caused when a mobile radio is transmitting too close to the TD100 components. This can happen when the system is installed in fiberglass tanks. In that case, a metal stilling well will need to be installed if the transmitted signal is too strong to isolate. Contact Titan Logix's Service Team for more information if you feel this is causing an issue for you.
