4.1.5 Wait for the reading to stabilize (when stays on the screen), then short press to finish the first point calibration. The tester returns to measurement mode and icon will appear at the bottom left, indicating a successful 1-point calibration (the middle point). 4.1.6 To calibrate second point, use pH 4.00 buffer and repeat Step 4.1.3 to 4.1.5 (Do NOT turn off the tester after you finish pH 7 calibration).
5. pH Measurement 5.1 How to take pH measurements Short press to turn on the tester. Rinse the probe in pure water, shake off excess water. Insert the probe in your sample solution, make a quick stir and hold still. Record the reading when it is stabilized ( comes up and stays on screen).

8.3.6 Factory default setting (P7): Select “Yes” to set the meter to its default status (erase all calibration record and return all parameter settings to the default value). This function can be used when the meter does not work well in calibration or measurement. Calibrate the meter again after setting the meter to factory default.
1-2 years depending on many factors such as frequency of use, nature of test samples, and how well it is maintained, etc. Apera Instruments recommends replacing the pH probe every 1 to 2 years to guarantee the optimal performance.
13. Notes Avoid testing in very high (>113°F) or very low (<41°F) temperature solutions as it will cause greater measurement error and potential damage to the probe. Test your samples and perform calibration close to room temperature as much as possible. b) NEVER store the probe in pure water like tap, RO, distilled, or deionized water as they could damage the pH probe.
15. Troubleshooting Guide Trouble Potential Reasons How to Fix When powered on, calibrate pH 7 first, then pH 4. After pH 4 is Incorrect calibration order calibrated, if you want to calibrate pH7 again, you need to power off and restart the tester. Bad standard solutions Replace with a new reliable buffer solution.
