Note:
the N-300G should be in the stopped mode
when performing the following calibrations.
Choose
*Set
in the main menu,
figure 88
.
Choose
*Cal
in the set selection menu,
figure 89
.
Choose
*Inputs
in the calibration set menu,
figure 90
.
Choose
*Pres
in the calibration menu,
figure 91
.
Choose
*XTank
in the Calibrate Pressure menu. The
transmitter voltage is 1-5VDC. The only field calibration
is the zero reference, which can be set in this display,
figure 92
.
Zero Adjustment
, is used to calibrate the N-300G con-
troller to a zero pressure reference point. The transmit-
ter is factory calibrated for the span value referenced to
a specific pressure above this set point.
To calibrate the zero set point
, remove all pressure
from the expansion tank by venting the expansion tank
pressure via valve
V-5
. The output from the transmitter
should be 1.00 VDC.
1. Press & release the
*Read
key,
figure 93,
and the
actual voltage present from the transmitter will be
shown flashing in the display.
2. Press & release the
*Accept
key ,
figure 94
, to
load the zero point into the memory. This value will
stop flashing when this is accomplished.
Note:
if an error message appears, figure 95, the volt
-
age is outside of the calibration range of .6V-1.4VDC.
3. If the odorant inlet transmitter requires zero calibra-
tion at this time, proceed to the
sure Transducer Zero Calibration on page 42
prior
to pressurizing the expansion tank.
3a.
Important
, If the odorant inlet transmitter is not to
be zero calibrated at this time, close
V5
and adjust
the expansion tank pressure back to 25 psi
(1.72
Bar)
, by manually opening valve
V4
until the proper
pressure is obtained, then close
V4
.
