Replacement/repair of main PC board is required
E-01
This means the interruption of measurement due to the
deterioration of inteferometric sensor.
Flashing of BRIGHT light means the decrease of light
amount for light source remarkably and flashing CONT
light means the decrease of contrast remarkably.
In any case, replacement/repair of interferometric
sensor is required.
E-02
This means the possibility of damage for setting data of
measuring gas or reference gas, a damage for alarm level
or sensor sensitivity data being set at maintenance
mode. Re-setting for various data or replacement/repair
of main PC board is required.
E-05
This means that the sample flow rate for sample gas or
reference gas to be supplied from GAS IN or REF IN is
zero.
It is thought that external pump, aspirator or reducing
