Operation

1. Remove the protective cap and protective film on the screen.
2. First rinse the electrode with purified water, and blot it with a paper towel to remove excess water.
3. Turn the meter on by pressing the “ON/OFF”key.
4. Immerse the pH meter electrode in the solution to be tested(do not exceed the immersion line)
5. Stir gently and wait around 30 seconds till the reading stabilizes.
6. After taking measurement ,rinse electrode with clean water, and power off by pressing “ON/OFF” button.
7. Always replace the protective cap after use.
8. It’s normal for the meter to display erratic values when first turned on and not placed in any liquid.

Operation

1. Take off cap and press “ON/OFF” button
   

2. Get reading
   

3. Replace the cap after rinsing off the electrode

Calibration:

1. Obtain,or prepare pH calibration standards,of 9.18,6.86 and 4.01pH by following the instryctions on the included calibration packets and Calibration Guide in this manual.
2. Turn on meter.
3. Immerse the electrode into the pH 6.86 standard. Temperature should be 25℃(77℉).
4. Press the “CAL”(calibration) button for 5 seconds and release.
   -Display will start flashing “6.86”.
   -Wait until the display stops flashing. The meter is now calibrated to a pH of 6.86. Proceed to nest steps to calibrate to a pH of 4.01 and 9.18. It’s important to calibrate to at least 2 different set-points. Rinse the electrode with purified water and blot dry with a paper towel in between each calibration step.
5. To calibrate to 4.01 pH immerse the electrode in pH 4.01 standard.
   -Press “CAL” button for 5 seconds. The display will begin flashing “6.86”. Immediately press “CAL” button while it’s still flashing to cycle to “4.01”.
   -Display will start flashing “4.01”.
   -Wait until display stops flashing. The meter is now calibrated to a pH of 6.86 and 4.01. Rinse and dry the electrode with purified water as before.
6. To calibrate at 9.18 pH, immerse the electrode in pH 9.18 standard and follow the calibration steps for a pH of 4.01.But cycle through this value until “9.18” is flashing (i.e., skip the 4.01 step.). -Display will start flashing “9.18”. -Wait until display stops flashing. The meter is now calibrated to a pH of 6.86,4.01 and 9.18.
7. To confirm the meter has been accurately calibrated, place the electrode into each of the calibration standards. Make sure to rinse the electrode with purified water between each test. If incorrect, repeat calibration starting with step 3.

Calibration Guide

Note:

Recalibration is required under the following conditions:
-Meter hasn’t been used for several months or more.
-Very frequent use.
-Critical accuracy is required.
-The “CAL” (calibration) button was pushed and the electrode was exposed to air, or not immersed in one of or the
3 calibration standards

Low Battery:

When the display is faded or not showing, then battery needs to be replaced. Please note the polarity of the
batteries when replacing.

Warranty:

The instrument is warranted to the purchaser for a year from the date of purchase. If during this period, repair or replacement of the instrument is required. Please contact us or your dealer and arrange for a Return Authorization. Damage caused by negligence or incorrect use, or battery failure, are not covered under warranty.

Display

Attention
