CL800 Intelligent On line Free Chlorine & pH Monitor
1. INTRODUCTION
The CL800 is a micro rocessor controlled Free Chlorine and H
measurement instrument. The unit utilizes a multifunction LCD to dis lay
readings and rovide feedback to the user. It is available with different
o tion to rovide fully configurable control, alarm and feedback with u
to four relays and two 4-20mA current out ut sources. It can be used to
detect the Free Chlorine and H value of the solution in chemical,
etroleum, rubber, a er, tobacco, alcohol, sugar, food, mining,
smelting, iron and steel, ower generation, harmaceuticals, water
treatment and other industries.

4. SETTING AND OPERATION
4.1 User Interface and Description
Front anel descri tion:
(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 H high or low alarm,
when the measured H 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

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 arameters.
(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 ，dis layed the measured values ( Free
Chlorine、H、℃），and can also be dis layed rom t function,
arameter values and error codes in interactive. (When measure
Free Chlorine only, H will be dis layed “none”, and tem erature will
be dis layed “25 ”℃)
4.2 Parameter Setting and Operation
When the instrument is owered security, after a brief self-test rogram,
Meas indicator lights and screen dis lay the Free Chlorine value, H
value, tem erature and time simultaneously as Figure 5. Indicates that the
instrument is working in the measurement state.
7

Instrument has two kinds of o erating states: "Measuring" state and
"Setting" state. In the measuring state, there are two kinds of dis lay:
“only Free Chlorine” and “Free Chlorine & H” dis lay status. Generally，
when the instrument is owered 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 oint ress the UP or DOWN
keys to select various setting functions, ress the MENU key to return to
measuring state.
If there is an error code “ER01” dis lay on the osition 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
e displayed “ER01”)
If there is an error code “ER02” dis layed, indicated the Free Chlorine
value is higher than measuring range.
If there is an error code “ER03” dis layed on the osition of the
tem erature, indicated that there is no tem erature in ut signal.
If there is an error code “NONE” dis layed in front of H, indicated that
there is no H in ut signal.

Instrument has the indication of cleaning function (o tional) on the screen.
When the cleaning function is o ened, there is a “●” mark on the screen
as Figure 7. When cleaning function sto ed, cleaning mark disa ear.

4.2.1 Password
The CL800 Monitor is locked to revent unauthorised access to the
configuration menu’s by using a assword. If you want to enter the
setting menu, you must enter correct assword.
The user assword is a 4 digit number that can be set to any value the
user chooses. When ress the MENU key, the screen will dis lay:
When su lied new, the user assword is set to 2223, we recommend that
this is changed when the instrument is installed. Use UP and DOWN to
modify it, then ress ENTER to enter the main setting menu.
*Note: The factory default assword is 2223, if the assword has been
forgotten lease contact Gold oint technical su ort.
