Operation level
Setting level
Service level
The operation of the FC400G free available chlorine analyzer (non-reagent type) is determined in the
following three control levels.
(1) Operation level
(2) Setting level
(3) Service level
The operation level applies to daily inspection or maintenance. Keystroke in this level can be
accomplished with the converter case cover installed.
The setting and service levels are used to select a function and set data. Function selection and data
setting are generally made once before starting operation. Also, inadvertent change of such selection
or setting should be prevented; operation keys used for the setting level or service level cannot be
externally accessible. To change such selection or setting, remove the converter case cover.

The FC400G can enter or exit from the operation level using the key. The operation level has the
following modes.
(1) MEASURE : Allows mg/l (or ppm) and auxiliary indications.

(3) DISP : Allows selection of the message area display content. Temperature, diffusion
current, applied voltage, output, slope, and zero point
(4) HOLD : Selects HOLD ON/OFF.
