What to do if Farringdon Measuring Instruments shift lights do not work?
If the shift lights on your Farringdon Measuring Instruments aren't working, first, ensure they are wired correctly, connecting black to black. Then, verify that the RPM settings for the shift lights are properly configured.
Why Farringdon Measuring Instruments tacho does not show correct rpm?
If your Farringdon Measuring Instruments tacho is displaying an incorrect RPM, the trigger pulse setting might be off. To resolve this, reset to the factory setup (refer to the start of section 3) and begin the setup process again. If issues persist, consider contacting Farringdon for further assistance.
How to fix unsteady main hand on Farringdon RCA5 Measuring Instruments?
If the main hand on your Farringdon Measuring Instruments is unsteady, it could be due to an irregular or too short trigger pulse. Try increasing the filter setting, or consider fitting a Filter Unit to stabilize the reading.
What to do if Farringdon RCA5 Measuring Instruments tacho runs against stop but shows no rpm?
If your Farringdon Measuring Instruments tacho runs against the stop upon power on but doesn't display any RPM, the issue might be a missing or incorrect trigger pulse. Ensure the trigger pulse exceeds 5 volts and drops below 0.2 volts. Setting the trigger pulse filter to 1 might also help.
Why Farringdon RCA5 Measuring Instruments main hand drops to 0 above a certain rpm?
If the main hand on your Farringdon Measuring Instruments drops to 0 above a specific RPM, the filter setting may be too high. Try reducing the filter setting to correct this issue.
How to troubleshoot no tacho hands movement on Farringdon RCA5 Measuring Instruments?
If the tacho hands on your Farringdon Measuring Instruments aren't moving when turned on, it could be due to a lack of power. Check for +12 volts between the red and black wires to ensure sufficient power supply.
