CL800 Intelligent On-line Free Chlorine & pH Monitor
1. INTRODUCTION
The CL800 is a microprocessor controlled Free Chlorine and pH
measurement instrument. The unit utilizes a multifunction LCD to display
readings and provide feedback to the user. It is available with different
option to provide fully configurable control, alarm and feedback with up
to four relays and two 4-20mA current output sources. It can be used to
detect the Free Chlorine and pH value of the solution in chemical,
petroleum, rubber, paper, tobacco, alcohol, sugar, food, mining,
smelting, iron and steel, power generation, pharmaceuticals, water
treatment and other industries.

4. SETTING AND OPERATION
4.1 User Interface and Description
Front panel description:
(1) CL alarm light，Under the conditions of setting Free Chlorine high or low
alarm, when the measured Free Chlorine value of the solution is
higher than the value of High alarm or lower than the value of Low
alarm, the CL alarm light will be turned on.
(CL high alarm light when only CL measuring)
(2) PH alarm light，Under the conditions of setting pH high or low alarm,
when the measured pH value of the solution is higher than the value
of High alarm or lower than the value of Low alarm, the PH alarm light
will be turned on.
(CL low alarm light when only CL measuring)
(3) UP key. In the setting state, using the UP key the user can cycle
through the front menu. To adjust a value, the UP key is used to

Figure 5 measurement state 1
increment the digit.
(4) MENU switch. Press this key to enter or exit the setting state.
(5) DOWN key，In the setting state, using the DOWN key the user can
cycle through the next menu. To adjust a value, the DOWN key is
used to select a digit.
(6) ENTER key is the enter button to confirm enter the menu and store
the setting parameters.
(7) Meas indicator light, the light will be turned on when entering the
measuring state.
(8) SET indicator light, the light will be turned on when entering the
setting state.
(9) LCD digital Monitor ， displayed the measured values ( Free
Chlorine、pH、℃），and can also be displayed prompt function,
parameter values and error codes in interactive. (When measure
Free Chlorine only, pH will be displayed “none”, and temperature will
be displayed “25 ”℃ )
4.2 Parameter Setting and Operation
When the instrument is powered security, after a brief self-test program,
Meas indicator lights and screen display the Free Chlorine value, pH
value, temperature and time simultaneously as Figure 5. Indicates that the
instrument is working in the measurement state.
7
Instrument has two kinds of operating states: "Measuring" state and
"Setting" state. In the measuring state, there are two kinds of display:
“only Free Chlorine” and “Free Chlorine & pH” display status. Generally，
when the instrument is powered on, it enter into the measuring state. Use
the MENU key to switch the "Measuring" state or "Setting" state. Press
MENU key in the measuring state, it will enter the setting state, and the
SET indicator light will be turned on. At this point press the UP or DOWN
keys to select various setting functions, press the MENU key to return to
measuring state.
If there is an error code “ER01” display on the position of measurement
reading as Figure 6, indicated the Free Chlorine value is lower than
measuring range. (In the case electrode unused for more than two hours,
it need activation for period of time, during which the meter readings will
be displayed “ER01”)
If there is an error code “ER02” displayed, indicated the Free Chlorine
value is higher than measuring range.
If there is an error code “ER03” displayed on the position of the
temperature, indicated that there is no temperature input signal.
If there is an error code “NONE” displayed in front of pH, indicated that
there is no pH input signal.
Figure 6 measurement state 2 (error code)

Instrument has the indication of cleaning function (optional) on the screen.
When the cleaning function is opened, there is a “●” mark on the screen
as Figure 7. When cleaning function stopped, cleaning mark disappear.

4.2.1 Password
The CL800 Monitor is locked to prevent unauthorised access to the
configuration menu’s by using a password. If you want to enter the
setting menu, you must enter correct password.
The user password is a 4 digit number that can be set to any value the
user chooses. When press the MENU key, the screen will display:
When supplied new, the user password is set to 2223, we recommend that
this is changed when the instrument is installed. Use UP and DOWN to
modify it, then press ENTER to enter the main setting menu.
*Note: The factory default password is 2223, if the password has been
forgotten please contact Goldpoint technical support.
