1 Preface
Thank you for selecting CLEAN meter.
Although the meter use advanced technology and meet the requirements of current safety rules,
improper use can still threaten the safety of users, and / or cause harmful influences to factory and
other equipments. Therefore, before using the meter, relevant person must read and understand
contents of this operation manual.
Besides the reasonable prices, Clean meters also have the following advantages:
- Simple operation. This operation manual provides you clear and easy operation guidance.
-Humanized design, Comfortable holding.
-Multiple accessories available, such as sensors, buffer solution etc.

Safety
- Never expose the meter in the explosive environment! Part of the shell case is
not airtight and the invasion of spark or the corrosion caused by the invasive gas
may cause explosion.
ee
- Please follow the operation manual and the laboratory safety regulations when
use the chemicals and solutions.
Safety precautions
>
-Never split the shell case.
-Only the OEM maintenance staff is allowed to maintain the meter.
-Following environment effect should be avoided:
Violent vibration
Expose to sunlight for a long time
Atmospheric humidity more than 9596
Corrosive gas
Ambient temperature below than -10'C or more than 60'C
Strong electric or magnetic field

2 Basic Operation
2.1 Battery — ( 200 Series )
PH200 / CON200 / DO200
Use a coin to remove the battery cover by following the "-"
direction.
Insert 2*1.5V 7AAA batteries in the battery compartment with
The correct Positive and Negative poles.
Tight the battery cover by following the "+" direction.
2.2 Electrode Installation
You can refer to the Electrode operation manual for use and maintenance. The direction of the red
dot marker on the Electrode and the salient point on the unit should be the same when install the
electrode to the unit. Remove the electrode by pulling out the clamp on the electrode.

2. Inset the electrode in the pre-set standard solution. You can refer to P-01 explanation on the
standard solution setting.
3. Press and wait the measuring value to be stabilized. Then press to confirm. The
offset slope will be shown after the calibration.
Note: System defaults first point calibration is 6.86pH or 7.00pH.
After the first point calibration, the second point calibration will begin automatically. Then the third
point calibration will be continued. The meter will back to measurement mode after all the
calibration is done.
Note:
You can press back to the measurement mode during calibration and all the calibration
point is saved. When the measured signal is out-ranged, the sign "Err" will be showed, possibly
the aging electrode or the polluted standard solutions lead to this.

5.5 Measurement Mode
1. You can first set the meter per your request. Otherwise, the setting will be factory defaults.
2. Use tap water or distilled water to clean the pH and the temperature electrode, removing the
adhesive impurities on the surface of electrode.
3. After power on, press to select the operation mode (pH or MV).
4. Immerse the pH and the temperature electrode in the solution and stir gently. The measuring
mark will twinkle. You can read the value once the data is stabilized and shows the stable mark.
