NOTE
4-20 MILLIAMPERE OUTPUT CALIBRATION
(4CAL)
The 801P5 is factory calibrated to generate 4 mA when the
pressure sensor is at 0 psig, and 20 mA when rated pressure is
applied. Tolerances in your signal conditioning equipment may
result in readings varying from these values, so you can calibrate
the 4-20 mA output as follows to correct these readings.
1. Connect a calibrated milliammeter to the 4-20 mA output.
2. Press
[MENU],
then press the
[UP/DOWN ARROW]
key
until
4CAL
is displayed.
3. Press
[SELECT]
. The display will show
LO-C
.
4. While reading the milliammeter, use the
[UP/DOWN
ARROW]
keys to adjust the output to 4 milliamperes.
5. Press the
[STORE]
key. The display will read
HI-C
.
6. Use the
[UP/DOWN ARROW]
keys to adjust the output to
20 mA, then press the
[STORE]
key to temporarily save the
calibration data and return to the main menu.
7. Press
[RUN]
and
[SELECT]
to save the changes and return
online.
If the 0 or Full Scale output has shifted by 4% of F.S.O. or more
from the factory calibration,
EROR
will be displayed.
