- Measurement in sample above the measuring range. Make sure sample is within the measuring range.
- Temperature of sample is above the measuring range. Make sure test sample is within the range of 0 to 50ºC
- Meter is out of calibration or calibrated with wrong standard solution. Re-calibrate meter only with specified standards.
- Sensor or circuit shorted due to water ingression. Water damage has no warranty.
- Meter is subject to extreme heat of above 70ºC. Circuit may be damaged by heat and cannot be repaired. Out of warranty.
- LCD damaged: The LCD display is damaged due to extreme shock or impact. Damages due to misuse is not covered under warranty.
If the damage is found out of a newly opened packaging box or used less than a year, then it is covered under product warranty.
- Software Hang: Remove batteries for 1 minute, replace and retest. If hanging persist, return for replacement
- Check if the batteries polarity is correctly placed according against the operations manual. If you lost the manual, you can download from the product page of your model, at the end of the page.- Check if you change all the batteries with new ones, this is because you won't know which battery is worn out frist. Even though they may have been changed later. Always make it a practice to change all batteries with new ones.
- Check if the old batteries were leaking and if the contact were coroded or leakage onto the circuit board. If so, the meter is damaged. Depending on the extend of the damage, in most cases, they cannot be repaired.
- Worn out battery or battery place incorrectly. Change all batteries and ensure batteries are placed in correct polarity.
- All pocket tester battery placement has the "+" polarity on the right side of battery holder with clip pointing downward.

All pH related Meter - Senz/ECO pH/pH Pro/pH Duo/ Redox / ArowanaPro
Sensor In Air - pH sensor need to contact with water in order to obtain a stable reading. When sensor is in air, it cannot make an electrical bridge between the glass sensor and the reference sensor, therefore, results in random or unstable reading. Once sensor is in contact with liquid, a stable reading will appear.
All pH meter needs to be re-calibrated regularly or as frequent as possible. If multiple measurements are made daily, then meter should be calibrated daily. If measurement is made once a day, then calibate at least once a week. Do remember that even if the meter is not used and put in storage, the sensor will change due to heat and humidity. Therefore, it is advisable to re-calibrate the meter after prolong storage. Due to dryness of sensor after prolong storage, soak sensor in water for at least 15 minutes before performing calibration.
Each meter has its own accuracy and deviations within the specification is normal. For example the pocket pH tester has an accuracy of +/-0.2pH, if the meter reading is at 7.5pH when compared to another meter in the same liquid, that other meter could read between 7.3 to 7.7 and is considered within specification.
Do take into consideration the temperature variation in the liquid when comparing data. Because all pH readings are affected by the liquid temperature. Therefore, it is logical to make measurements with any liquid at about the same temperature.
Maintenance must be observe to keep the sensor in good condition. Always rinse sensor with water after measurement and before storage. If measurement is accidentally made in oil tainted liquid, oil film may be deposited on the glass sensor as well as the reference sensor. Dip sensor in warm mild liquid detergent for 1-2 minutes, then use a cotton bud and gently rub only the glass sensor. Rinse sensor thoroughly with water. Re-calibrate and retest. If the sensors are badly soiled, it may permanently damage the sensor, which result in inaccurate or very sluggish reading. This is not covered under the warranty.

- Dry sensor. The pH glass sensor requires a fully hydrated surface contact with the measuring liquid in order to obtain a stable reading. If the sensor is out of the box or had been kept in storage for a long time, soak the sensor in tap water for 10 to 15 mintues to regain the hydrated surface on the sensor. Measuring speed will be improved significantly.
- Always re-calibrate meter after prolong storage and before measurement.
- If the reading is still sluggish after soaking in water, then the sensor could be expired. Extensive and intensive testing will significantly reduce sensor life and cause premature expiry. The lifespan of the pH sensor is about 365 tests or about 1 year, whichever is earlier. Sensor expiry is not covered under product warranty.

The lifespan of the pH sensor is about 365 tests or about 1 year, whichever is earlier. Sensor expiry is not covered under product warranty.
- Magnetic interference from high power station or equipment. The pH sensor measures minute electrical signals at the molecular level, therefore, it is a very sensitive instruments and can pick up strong electro-magnetic signals. Try moving to another location to perform the test.
- Water damage: Water leaked into electronics of the unit due to submersion under water or improper battery cap closure. Water damage is not cover under warranty.
- Sensor damaged: Sensor could be damaged or broken. Observe the pH glass sensor to look for any cracks or miro-cracks. If the product had been subject to extreme shock or impact, it can be damaged. Damage due to misuse is not cover under warranty. If the damage is found out of a newly opened packaging box, then it is covered under product warranty.
- Sensor Expiry: Intensive testing will significantly reduce sensor life and cause premature expiry. Storing the sensor without its protective cover or soaking bottle will result in premature expiry. Continuous soaking sensor in water for days or weeks will cause premature expiry. The lifespan of the pH sensor is about 365 tests or about 1 year, whichever is earlier. Sensor expiry is not covered under product warranty.

All EC/Conductivity related meter - Senz uSiemen/mSiemen/TDS / KoiMedic / DiscuSoft / Nutrient Check / CrystalShrimpPro
- Measurement in moving water may result in unstable reading. As Conductivity readings are temperature dependant, making measurement in moving water of varying temperature will result in instability.
- If the sensors are not rinsed after each tests and not rinsed before storage, residule and oily deposits on the sensor will cause reading to be lowered. Rinse the sensors in warm dilute dish washing liquid and soak for 5 minutes. Rinse thoroughly with water and re-test. Calibrate the unit with the recommended calibration fluid.
- If oily deposits is on the sensors, rinse the sensors in Alcohor for 20 seconds. Rinse with water then perform a calibration using the recommended calibration fluid.
- Calibration is recommended for every 6 months.
- Magnetic interference from high power station or equipment or power line. The Conductivity meter measures minute electrical signals and can pick up strong electro-magnetic signals. Try moving to another location to perform the test.
- It could due to dirt stays between the sensor. Check if there are any dirt, hair or even a layer of wet film between the sensors will cause
- It could be due to environmental difference between the place of manufacturing and the local environment. A software reset is necessary to zero the circuit as follows:
1. Remove the battery cap.
2. Press and hold-down the MODE or CAL button and simultenously insert the battery cap, then release the button.
3. "C00" will appear in a flashing mode then stop.
4. Reset completed and display return to zero.
