Daniel MeterLink utility Diagnostics Action(s)
MeterLink Tools Menu • Frequency output • Run the Frequency Outputs
test
• If the output reads zero,
you may require a pull up
resistor 1.2kOHM, 0.5W.
• Analog outputs • Run Analog Outputs test
• Verify outputs are within
4mA-20mA range
- 0% = 4mA
- 25% = 8mA
- 50% = 12mA
- 75% = 16mA
- 100% = 20mA
• Digital outputs • Run the Digital Outputs
test.
• Digital Output Content is in
relation to frequency validi-
ty and flow direction con-
figuration and polarity.
Meter Electronics • Acquisition Module com-
munications error
• Check firmware revision
and upgrade if necessary
using Daniel Meter-

Download.
• If LED 4 and LED5 are not
Solid Green check intercon-
