z
Check of converter and detector installation condition. (Refer to “ Installation method ”
(page 11))
z
Check if the wirings are correct. (Refer to the “ Wire connection ” (page 16))
z
Are the terminal block screws firmly tightened?
z
Is the fluctuation of the power supply voltage within
±
10
%
of the rated voltage?
z
Check if the piping for mistake. (Refer to the “ Piping ” (page 12))
z
The piping and wiring for the solenoid valve to control zero calibration should be properly
carried out.
(Refer to “ Auto zero calibration ” (page 54))
z
The ceramic beads should be properly filled in the bead tub. (Refer to “ Cleaning/
replacing the bead filter A, bead filter and ceramic beads ” (page 50))
z
The sampling flow rate can be adjusted within 0.1 and 0.5 L/min. (Refer to “ Checking the
sample flow rate ” (page 47))
z
Initial setup (selection of transmission signal setting, operation condition settings for relay
contacts, etc.)
z
Calibration (zero and span) (Refer to “ Calibration ” (page 53))
J
Initial setup
The converter is shipped with initial settings.
