What to do if there are no output pulses from the DANIEL 1500 Measuring Instruments amplifier module?
- BBrenda HughesJul 30, 2025
If there are no output pulses from the amplifier module, several factors could be at play. First, ensure the input voltage to the amplifier is within the required range of 10-30 VDC. If the voltage is correct, the pickoff might be damaged or shorted; its resistance across the leads should be between 600-900 Ohms, consider replacing it. A damaged amplifier module could also be the culprit, in which case, replace it. Finally, troubleshoot the internal assembly to ensure the meter rotor is turning.
