Troubleshooting Siemens MultiRanger/HydroRanger mA Inputs

Recently, I was helping a customer troubleshoot the analog input on his Siemens MultiRanger 200.
For common troubleshooting, using voltage values to confirm a zero, mid point and span is all that’s needed. I find it easier to put a voltmeter across the analog input and read the voltage drop than to wire an amp meter into the circuit to read directly, but that assumes that the analog input’s resistor value is a known. For the most commonly used input resistance (250 ohms), the equivalent voltage drop is 1.0 to 5.0V.
Being the guy who actually reads the user manuals, I looked in the Siemens manual to find the input resistance, and it’s not there.
The 15-30-15 Rule in Ultrasonic Level Measurements

If I’ve heard it once, I’ve heard it a dozen times when talking with a Siemens support guy while evaluating a problematic ultrasonic level measurement application,
“What’s the echo confidence and strength?” “What’s the noise measurement?”
Those are numbers that quantify the echo quality: the floor values for echo confidence and strength and the ceiling value for the noise. I’d look up the value and the guy on the phone would tell me whether the number was good, bad or so-so. Finally, someone wrote down what those values should be, and they’re worth filing for future reference.

Move New Multi/HydroRanger Level Controller Guts into an Existing Multi/HydroRanger Enclosure
Written by: Dan Weise
The venerable Siemens Milltronics line of level controllers, the MultiRanger and HydroRanger Series, recently received a major update. The new models have high resolution LCD displays and built-in configuration tools with English language menus. Configuration time is reduced significantly without the need to reference manuals for parameter codes. These updated models have ‘HMI’ in the model name: MultiRanger HMI or HydroRanger HMI.
