installed, you will see the following display:
†
An actual flow value is displayed when the gases are off or not connected. This is not an
error. After the gases are connected and the detector is operational, the actual flow values
will be equal to the setpoint values.
7. If you have an EPC detector, zero the pressure sensors:
a. Make certain that your detector and makeup gases are not
connected to your detector.
b. Press [Options] and scroll to Calibration Front detector or
Back detector.
c. Scroll to Oxidizer zero and press [On].
d. Scroll to H2 zero and press [On].
e. Scroll to Makeup zero and press [On].
8. Turn the GC off and unplug the power cord. Plumb the air, hydrogen,
and makeup gases to your detector. See the Site Preparation and
Installation Manual for instructions.
