•
Display CG, PWR
= Factory use only.
•
Internal Temperature
= Electronics temperature.
5.1.2
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
