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.
