Column Two Hidden Diagnostics Values

• 4-20(1) Zero = Analog counts to calibrate zero on analog output 1.
• 4-20(1) FScale = Analog counts to cal. full scale on analog output 1.
• 4-20(2) Zero = Analog counts to calibrate zero on analog output 2.
• 4-20(2) FScale = Analog counts to cal. full scale on analog output 2.
• 4-20(3) Zero = Analog counts to calibrate zero on analog output 3.
• 4-20(3) FScale = Analog counts to cal. full scale on analog output 3.
• Ext. 4 mA Cal. = Enter 0 for auto calibration or enter factory supplied A/D counts. Note: You must connect a
known 4.00 mA input if you are going to calibrate the unit.
• Ext. 20 mA Cal. = Enter 0 for auto calibration or enter factory supplied A/D counts. Note: You must connect a
known 20.00 mA input if you are going to calibrate the unit.
• External Input = Enter what the external 4-20 mA input represents, i.e. Temperature 1, Temperature 2, or
Pressure. The meter will use this for its internal calculations.
• Ext. Full Scale = Enter the full scale units that correlate to the 20 mA point. Note: It must be in the units for the
selected input type such as Deg F, Deg C, PSIA, Bar A, etc.
• Ext. Zero Scale = Same as previous value, but for the 4 mA point.
• Alarm (1) Test = Used as a test to verify that the alarm circuit is functioning. When low is selected the alarm will
initiate a low alarm on the output. When High is selected it will give a high alarm on the output.
• Alarm (2) Test = Used as a test to verify that the alarm circuit is functioning. When low is selected the alarm will
initiate a low alarm on the output. When High is selected it will give a high alarm on the output.
• Alarm (3) Test = Used as a test to verify that the alarm circuit is functioning. When low is selected the alarm will
initiate a low alarm on the output. When High is selected it will give a high alarm on the output.
• Reynolds Corr. = Reynolds number correction for the flow profile. Set to Enable for MV82 insertion and set to
Disable for MV80 inline.
• Gain Control = Manual gain control (factory use only). Leave set at 1.
• Filter control = Manual filter control. This value can be changed to any number to force the fi value to a
constant. A value of zero activates the automatic filter control which sets fi at a level that floats above the f
value.
• High Pass Filter = Filter setting - Factory use only
• Factory Defaults = Reset factory defaults. If you change this to Yes and press ENTER, all the factory configuration
is lost and you must reconfigure the entire program. Consult the factory before performing this process, it is
required only in very rare cases.
• Meter Type = Insertion (MV82) or Inline (MV80) meter.
• Config Code = Factory use only.
• Test Pulse Out = Force totalizer pulse. Set to Yes and press ENTER to send one pulse. Very useful to test totalizer
counting equipment.
• Test Scaled Freq = Enter a frequency value to test the scaled frequency output. Return to 0 to stop the test.
• Output Type = Factory use only.
• Calibration Mode = Factory use only.
• A2D Ref. Resistor = Factory use only.
• Pressure Cal Current = Calibration value for the electronics and pressure transducer combination. Consult
Factory for value.
• Pressure 9Cs = Nine pressure coefficients unique to the pressure transducer. Use the RIGHT ARROW to access all
nine coefficients.
• Press. Max psi = Based on installed sensor.
• Press. Min psi = 0 psia
