Analog Flow Input Calibration,
1-5 VDC / 4-20 mA,
Continued
To calibrate the zero set point,
figure 81, apply 1.00
VDC (4.0 mA) to the TB1 terminal #2 (+ positive signal
input) and terminal #3 (- negative signal input). If a
Differential Pressure Transducer – DPT is used, output
from the transmitter should be 1.00 VDC
(4.0mA) at 0
inches of water column differential
(0” w.c.).
1. Press & release the *Read key and the voltage
present at the input terminals will be shown flashing
in the display.
2. Press & release the *Accept key to load the zero
point into the memory. This value will stop flashing
when this is completed,
figure 82.
Note: if an error message appears, figure 83, the
voltage at the input terminal is outside of the calibration
range of .6V -1.4VDC (2.4 mA - 5.6 mA).
Choose Span to calibrate the full span set point,
figure
84, the span adjustment is used to calibrate the N-300G
controller for 100% of metered flow in the pipeline. The N-
300G is factory calibrated for 100% of flow to directly
correspond to 5.00 VDC
(20 mA) at the flow input terminal
board TB1 terminals #2 and #3,
refer to the Wiring Control
Document on page 117 in Appendix D.
To calibrate the span set point, apply 5.00 VDC (20 mA)
to TS2 terminal #2
(+ positive signal input) and terminal #3
(- negative signal input). If a DPT is used, output from the
transmitter should be 5.00 VDC
(20 mA) at maximum
range of the meter, for example 5.00 VDC
(20 mA) at 100
inches of water column differential (100” w.c.).
1. Press & release the *Read key and the voltage
present at the input terminals will be shown flashing
in the display,
figure 85.
2. Press & release the *Accept key to load the span
setting into the memory. This value will stop flashing
when this is completed,
figure 86.
Note: if an error message appears, figure 87, the
voltage at the input terminal is outside of the calibration
range of 3.0V-5.5VDC (12 mA - 22 mA).
