4.Preparation Before Use

If it is first-time use or the tester hasn’t been used for over 30 days, pour a little 3M KCl storage

solution in the probe cap (about a fifth of the probe cap), and soak the probe for about 5 to 15

minutes. Do NOT let the storage solution come in contact with the BPB sensor (two black rods),

since it could cause potential damage to the sensor. The black fill line on the cap does NOT

indicate how much the KCL soaking solution should be poured in. The volume of KCL solution

poured in should be less than that. The black fill line indicates the minimum volume for sample

testing in the probe cap. To achieve maximum accuracy for pH testing, we recommend soaking the

probe for one night (12 hours) to activate the glass membrane thoroughly.

When not in use, we recommend store the pH probe in the storage solution (do not let the solution

contact BPB sensor). But even if stored dry, it won’t do any damage to the sensor. Users just need

to restore the sensor’s sensitivity by soaking it again.

5.pH Calibration

5.1 Rinse the probe in pure water and dry it.

5.2 Pour certain amount (about half volume of the calibration bottle) of pH 7.00 and

pH 4.00 buffer solution in separate calibration bottles;

5.3 Long press to enter calibration mode; Short press to exit.

5.4 Dip the probe in pH7.00 buffer solution, stir gently, and allow it to stand still in

the buffer solution until a stable reading is reached. When stable icon is

displayed on the LCD screen (as shown in Diagram 3), short press to

complete 1-point calibration and the tester returns to measurement mode.

Indication Icon will appear at the bottom left of the LCD screen.

5.5 Rinse the probe in distilled water and dry it. Long press to enter calibration mode.

Dip the probe in pH 4.00 buffer solution, stir gently, and allow it to stand still in the buffer

solution. When stable icon is displayed on the LCD screen, short press to complete

2-point calibration and the tester returns to measurement mode. Indication icon will

appear at the bottom left of the LCD screen.

5.6 If necessary, rinse the probe in distilled water and dry it, and dip the probe in 10.01 buffer

solution (sold separately) to complete 3rd point of calibration according to the steps in 5.1 to 5.4

will appear at the bottom left of the LCD.

■Notes

a) Tester will automatically recognize pH buffer solution. Users can perform one-point, two-point,

or three-point calibration. But for the 1st point calibration, only 7.00 pH solution can be used.

Then use other buffer solutions to conduct 2nd or 3rd point calibration. Tester will

automatically recognize 5 kinds of pH buffer solutions. Refer to the table below:

b) For pH Calibration buffer solutions, we recommend that users replace new buffer solution

after 10 to 15 times of use to keep the standard buffer’s accuracy. Do NOT pour the used

calibration solutions back into the solution bottles in case of contamination.

c) pH probes will NOT give accurate and stable readings in distilled or deionized water. This

is because distilled and deionized water do not have enough ions present for the electrode

to function properly. Do NOT store pH probe in distilled water to prevent damage.

d) For the self-diagnosis information, please refer to the table below:

Self-Diagnosis information

Checking and methods to fix

Wrong calibration solution or the range of

calibration solution exceeds standard.

a) Check if calibration solution is correct (1st point

of pH calibration must be pH 7.00)

b) Check if electrode isdamaged.

c) Start over calibration with pH7.00 first, then

pH 4.00 or 10.01

6.pH Measurement

Short press to turn on the tester. Rinse the probe in distilled water and dry it. Dip the probe in

sample solution, stir gently, and allow it to stand still in the solution. Get readings after

comes up and stays.

7.Conductivity Calibration

7.1 Press key to switch to conductivity measurement mode. Rinse the probe in distilled water

and dry it.

7.2 Pour certain amount (about half volume of the calibration bottle) of 1413μS and 12.88mS

conductivity calibration solution into accordant calibration bottles.

7.3 Long press key to enter calibration mode, short press to exit.

7.4 Dip the probe in 1413 μS conductivity calibration solution, stir gently and

allow it to stand still in the solution until a stable reading is reached. When stable

icon appears on the LCD screen, short press key to complete one-point

calibration, the tester returns to measurement mode and indication icon will

appear at the bottom left of the LCD screen.

7.5 After calibration, dip the probe in 12.88 mS conductivity calibration

solution. If the value is accurate, it is not necessary to conduct 2nd point

calibration. If it is inaccurate, follow the steps in 7.1 to 7.4 to complete the 2nd point of calibration

using 12.88 mS buffer solution.

8.Conductivity Measurement

Press key to turn on the tester. Rinse the probe in distilled water and dry it.

Dip the probe in sample solution, stir gently, and allow it to stand still in the solution until a stable

reading is reached. Get readings after comes up and stays. Press to switch from

Conductivity to TDS/SAL/pH.

■Notes

a) The tester uses 84μS, 1413 μS and 12.88 mS conductivity calibration solution. User

can conduct 1 to 3 points calibration. Refer to the table below. Usually calibrating the

tester with 1413 μS conductivity buffer solution alone shall meet the testing

requirement.

b) The tester has been calibrated in factory. Generally, users can use the tester directly or users

can test conductivity buffer solutions first. If the error is large, then calibration is needed.

c) For conductivity calibration solutions, we recommend that users replace new solutions after 5 to

10 times of use to keep the standard solution’s accuracy. Do NOT pour the used calibration

solutions back into the solution bottles in case of contamination.

d) Temperature compensation factor: The default setting of the temp. compensation factor is

2.0%/℃. User can adjust the factor based on test solution and experimental data in parameter

setting P4.

e) TDS and conductivity is linear related, and its conversion factor is 0.40-1.00. Adjust the factor

in parameter setting P5. The factory default setting is 0.71. Salinity and conductivity is linear

related, and its conversion factor is 0.5. The tester only needs to be calibrated in Conductivity

mode, then after calibration of conductivity, the meter can switch from conductivity to TDS or

salinity.
