STAND-BY xx:xx
Displayed for 20 minutes after the instrument is
turned on.
Since the heaters and optical system are unstable
during the countdown, measurement data is not
reliable.
Close the door of TC-WA.
(Only when TC-WA is connected)
Displayed if the door is open when the TC-WA tries to
drive a component.
When the door is closed, the process is restarted.

01
A/D FULL
The voltage of the A/D
converter of the optical
system exceeds the preset
value.
Issued if any voltage of SIG1, REF and SIG2 is 5 V or
more.
Possible causes are an increase in the light quantity of
the lamp, an increase in the sensitivity of the phototube,
and an abnormality in a circuit.
If the error persists even after the adjustment of the
optical system described before is made, contact us.
02
LAMP BROKEN
The light quantity of the lamp
(REF voltage) decreases
below the preset value.
Issued if the “REF” voltage is 0.5 V or less.
Possible causes are the deterioration of the lamp and
an abnormality in the phototube to correct the light
quantity or in a circuit.
If the error persists even after the adjustment of the
optical system described before is made, contact us.
03
CELL DARK
Absorption cell is soiled.
Issued if the absorption cell is dirty and the voltage ratio
of “REF” to “SIG1” is 3 or more. Clean the absorption
cell.
04
MOTOR ALARM(PUMP)
The alarm is output from the
IC for driving air pump.
Issued if the IC to drive the air pump is abnormal.
If the error persists even after the instrument is
restarted, contact us.
06
COOLING ERROR(H1)
FAN1 may not be running.
Issued if the temperature of the H1 is 150
°
C or more at
the end of the cooling. The fan may not be operating or
the cooling time may be short.
07
COOLING ERROR(H2)
FAN1 may not be running.
Issued if the temperature of the H2 is 300
°
C or more at
the end of the cooling. The fan may not be operating or
the cooling time may be short.
08
COOLING ERROR(H3)
FAN1 may not be running.
Issued if the temperature of the H3 is 150
°
C or more at
the end of the cooling. The fan may not be operating or
the cooling time may be short.
