What to do if my Seametrics iMAG 4700r Measuring Instruments display is blank?
- A
  Adam MosleyAug 14, 2025
  If your Seametrics Measuring Instruments display is blank, it could be due to several reasons: * Check the wiring from the power source to the meter for any incorrect connections. Use a DMM to measure the voltage at the terminal block TB1 on the back of the display, ensuring correct polarity and a steady voltage between 9Vdc and 32Vdc. * Ensure the backup battery is properly plugged in. * If the battery is plugged in, it may be dead and require replacement.

Why is the pulse/frequency output erratic on my Seametrics Measuring Instruments?
- T
  Tara GardnerAug 23, 2025
  If the flow rate on your Seametrics Measuring Instruments appears correct, but the pulse/frequency output is erratic or too high, the issue might stem from electrical noise interfering with the pulse frequency signal. Try to isolate, remove, or reduce these noise sources. Also, ensure you are using the correct type of cable – only twisted pair cable should be used, with both signal wires on the same twisted pair. A grounding problem could also be the cause, so try improving or changing your grounding method.

How to fix low pulse/frequency output on Seametrics Measuring Instruments?
- L
  Lisa PetersAug 30, 2025
  If the flow rate on your Seametrics Measuring Instruments appears correct, but the pulse/frequency output is low, erratic, or absent, there are a few potential causes. First, verify that the wiring is correct by comparing it with the recommended wiring diagram. Second, the external device input impedance might be too low; try using a sourcing rather than a sinking interface connection. Finally, if the cable is too long, reduce the interface pull-up resistance.
