Function of judging whether the detection tube is clean
This function judges whether the detection tube is clean when the washing process ends after manual/auto operation.
When the washed detection tube is not clean
When it is judged the detection tube is not clean, "Warning: cell too dirty" is displayed on screen.
When this message is displayed, manually wash the detection tube (see “8-2-1”), shut off the primary power supply and clean the sensor
(with brush, see”8-4”). After that, the primary power supply again and perform manual running using mineral water (see “8-1-1”).
Since stain level of sample water detection tube is judged after manual operation is finished, this message disappears when the detection
tube is clean. If the message is still displayed, repeat the above steps. (clean the sensor (with brush, see”8-4”), manual operation using
mineral water (see “8-1-1”) and judging the stain level of sample water detection tube).

When th-e inside of the detection tube is too dirty to be measured
"Warning [112]" is displayed on screen when the inside of the detection tube is too dirty to be measured.
Clean the sensor (with brush, see”8-4”) to maintain the performance of the detector. It is necessary to temporarily cancel the Warning state
to enable sensor cleaning (with brush, see”8-4”). Press “Enter.” Then display changes to “Warning: cell too Dirty.” Shut off the primary
power supply, and clean the sensor (with brush, see”8-4”). After that, supply the primary power supply again and perform manual
operation using mineral water. (see “8-1-1”) Since stain level of sample water detection tube is judged after manual operation is finished,
this message disappears when the detection tube is clean. If the message is still displayed, repeat the above steps. (cleaning the sensor
(with brush, see “8-4”), manual operation using mineral water (see”8-1-1”) and judging the stain level of sample water detection tube).

Ɣ When warning message still remains on screen after the sensor cleaning (with brush), the fresh water may be
contaminated. Do not use industrial water or circulating reclaimed water in the fresh water line since such water may
be cloudy or contaminated.

This
oil concentration detector is equipped with a “Zero-point compensation” function. However never use this function
when “Warning: cell too dirty” or ”Warning [112]” (to alarm dirtiness of sample water detection tube) is displayed on
screen. If used, a detector trouble may occur.
