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.

4.2.2 Main Setting Menu Directory
Figure 8 main setting menu directory
After entering into the setting menu, the main menu is dis layed on the
screen as Figure 8. By ressing the UP and DOWN keys to select menu
o tion, then ress the ENTER key to enter this menu subdirectory.
4.2.3 Set Parameter

4.2.3.1 Set Free Chlorine Measuring Range
Select “Set CL Range”, ress
ENTER key to enter the next menu
level.
When the character starts flashing,
ress DOWN key to select the digit,
the UP key is to modify the selected
digit. After modifying the value,
ress ENTER key to save and
return to the revious menu.
※ This value must be equal to the measurement range of the
chlorine electrode.
4.2.3.2 Set CL PH Compensation Mode
Press UP and DOWN keys to switch
"ON / OFF", ress ENTER to
confirm.
Because chlorine value changes is affected by PH value changes, So
when the PH value is higher than 8.00 H or lower than 6.00 H, it need to
set CL-PH Com ensation to "ON".
4.2.3.3 Set PH Temperature Compensation
(
This function is disabled when Free Chlorine only)
11

CL800 has Auto and manual tem erature com ensation function. Use
manual tem erature com ensation, according to the manual in ut
tem erature value to com ensate. Use automatic tem erature
com ensation, according to the measuring tem erature value by the
tem erature sensor to com ensate.
Press UP and DOWN keys to select
“Auto” or “Manual”, ress ENTER
key to confirm.
When selected tem erature com ensation mode to manual, you need to
enter the tem erature value. Range is 0~100℃, and the factory default is
25.0℃.
The tem erature com ensation coefficient is different for each ty e of
solution, so the tem erature com ensation coefficient is designed to be
adjustable(25 ℃ as the reference), and the range is -2~+2%/℃. The
tem erature com ensation coefficient works both in automatic and manual

(minute).
*Note: " Clean Duration " and " Clean Interval " can not both be set to 0.
Sensor cleaning equi ment is the o tional configuration, lease confirm
the device are connected correctly before set cleaning to “ON”.
4.2.4 Set Alarm
The CL800 monitor has four alarm out uts designated high alarms(H)
14

and low alarms(L). The alarm value and alarm hysteresis can be set
within the currently selected measuring range.
Alarm Relay
During normal o eration when the alarm is not active, the alarm out ut
will be in its NORMAL condition, the N/O (normal o en) contact will be
o en. When the alarm is active, the alarm out ut will be in its ALARM
condition and therefore the N/O contact will be closed.
Alarm Hysterisis
In a normal condition an alarm turns on and off at the same value. For
exam le, if a high alarm turns on at 10.00 H the alarm occurs when the
reading increases to 10.00 H. When it decreases through 10.00 H the
alarm turns off.
Some a lications may demand that the alarm turns off at a different
value, for a high alarm this would be value lower than the alarm value,
and for a low alarm this would be a value higher than the alarm value.
The hysterisis value determines the difference between the alarm switch
on oint and the alarm switch off oint. In the case of a high alarm,
hysterisis causes the alarm to turn off at a value that is less than the
alarm value. For a low alarm, hysterisis causes the alarm to turn off at a
value greater than the alarm value.

Select “Set Alarm”, ress ENTER key to enter the next menu level.
Press UP and DOWN keys to select the item you want to modify, then
ress ENTER to enter into. When the character starts flashing, ress
DOWN key to select the digit, the UP key is to modify the selected digit.
After modifying the value, ress ENTER key to save and return to the
revious menu. The factory default alarm value as below:
CL H Alarm 2.00 m PH H Alarm 13.00 H

CL L Alarm 0.10 m PH L Alarm 1.00 H
CL L Hysteresis 0.01 m PH L Hysteresis 0.10 H

*Note: The setting should meet (high alarm - high hysteresis)≥(low alarm +
low hysteresis)
4.2.5 Set Current Output
CL800 has two 4~20mA current out uts. One in ut source is H or ORP
and the other is tem erature. The current out ut can be set work over the
whole range of the in ut source.
The out ut can be set work over the whole of selected measurement
range (curve1) or a ortion of it by setting of the out ut start and end
values (curve2).
Select “Current Out ut”, ress ENTER key to enter the next menu level.
