Software
pH calibration• Prepare pH standard solution 6,86 dan 4,01
with calibration container.• Wash the sensor module, wipe the water off.• Immerse the electrode to calibration
container.• Wait stabilized. Press CAL/ENT two second or
more.• are blinking, beep sounds.• pH is stabilized, beep sounds again, mark
are displayed.• Wash again the sensor module, wipe the
water off.• Repeat the same procedure for pH 4,01.
DO Calibration1. Span Calibration.• Put small volume of water to Calib. Container.• Push the sensor module deep into Calib. Container.• Leave it 20 minute or more, until stabilized• Press CAL/ENT, 2 second or more, calibration mark
are dispalayed.2. Zero Calibration.• Prepare 5-10% Sodium Sulfit solution. Immerse the
sensor module• Press CAL/ENT, 2 second or more, calibration mark
are displayed.
Salinity Measurement• The Salt content, TDS and SSG are determined
by conversion from the Electric Conductivity (EC).
• Calibration is normally unnecessary.• Possible conversion beetwen the NACl
conversion and Salt content of Saline water.• The NaCl conversion concentration is percent
(%)• The Salt content based upon the definiton by
UNESCO (1998)
Electric Conductivity
A. The EC has been coincided with cell constan when shipped from the factory.
B. It calibrate when the cell constan to be changed.
C. 1-point calibration using Pottasium Chloride standard solution (B Solution) JIS K0130
D. Does not require calibration in the first year of use.
1. Pour B Solution on a beaker, Display (COND) on the screen.
2. Immerse the module, upon the indication is stabilized, press key 2 > second.
3. Set the calibration value of B Solution using or and press key.4. Calibration is started with and flashing .5. The calib. mark is shown on the screen
with a beep at 10 sec later.
