4-20(1) Zero Analogue counts to calibrate zero on Analogue output 1.
4-20(1) FScale Analogue counts to cal. full scale on Analogue output 1.
4-20(2) Zero Analogue counts to calibrate zero on Analogue output 2.
4-20(2) FScale Analogue counts to cal. full scale on Analogue output 2.
4-20(3) Zero Analogue counts to calibrate zero on Analogue output 3.
4-20(3) FScale Analogue counts to cal. full scale on Analogue output 3.
Ext. 4 mA Cal.
Enter 0 for auto calibration or enter factory supplied A/D counts.
Note: You must connect a known 4.00mA 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, Psi a, Bar A, etc.
Ext. Zero Scale Same as above 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.
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
