Conditioning Before First Use: Precipitation of the sensor electrolyte may cause white
crystals to form around the cap. This is normal and does not affect the tester’s performance.
1. Fill the transparent cap of the tester with 20 mm of tap water
2. Recap the tester and soak* tester for one hour
3. Rinse the cap after use
4. The sensor is now activated and ready for use
Testing:
1. Remove cap and press to turn on the tester
2. Dip sensor in at least 20 mm of test solution
3. Stir once and let the reading stabilize. Note the measured value
4. To hold reading, press . Screen flashes
HO once, then displays measurement
with blinking unit (pH) to indicate that tester is in the hold mode. Press again to
cancel hold mode (
HC )
5. Press to shut the tester off
Note: Tester automatically shuts off after 8.5 minutes of non-use to conserve batteries.
Calibration: The tester is factory calibrated. However, to ensure accuracy, regular
calibration is recommended.
1. This tester allows up to 3-point calibration. Start with pH 7.00 buffer
2. Press to turn on the tester
3. Dip sensor in 20 mm of standard solution, stir gently and wait for the value to
stabilize at or near pH 7.00
4. Press to enter the calibration sequence. Display flashes
CAL momentarily, then
shows a flashing default reading
5. To confirm calibration, press and wait for the auto confirmation (
En )
6. You have successfully completed the first calibration point
7. To obtain your second and third calibration points, proceed to the next buffer value
(pH 4.00 or pH 10.00) and repeat step 3 - 6
8. To abort calibration, press to escape (
ESC )
Maintenance:
1. Rinse sensor in tap water after each use
2. In harsh samples, take readings quickly, then rinse sensor with de-ionized water
immediately to remove residues and prevent electrode contamination
Useful Notes:
1. To avoid cross contamination, rinse between samples and calibration standards with
de-ionized water
2. To maintain tester accuracy, use tester regularly or calibrate at regular intervals as required
3. For long-term storage, fill cap with 20 mm of storage solution (NOT de-ionized water)
and replace cap*. This will keep sensor conditioned and ready for next use
* The tester cap is not leak-proof. Please keep tester upright during soaking.

Lift and hold
Changing Batteries:
1. To remove batteries, lift up the front battery cover to release the front catch. Push up
and hold in that position
2. Next, lift the pocket clip to release the back catch and slide upwards to remove the
battery cover (Figure 1)
3. Replace old batteries with fresh ones. Note polarity as shown in battery compartment
4. No re-calibration is required after battery change. The tester’s non-volatile memory
function retains calibration settings
Error Messages:
1.
bA – Batteries are weak and need replacement
2.
Err – Wrong or bad buffer value (out of range) and/or the sensor is failing.
Use fresh buffer
3.
Or/Ur – Over or Under range signal, or sensor is contaminated/damaged/not
fully immersed
Reset Option: Reset option allows you to restore the calibration back to factory
default settings.
1. Press to turn off tester
2. Press and hold , then press to turn the tester on. The display shows a
flashing
