Operating a Water Quality Tester:

Read the User Manual:

  • Begin by thoroughly reviewing the GAO Tek’s Water Quality Tester’s user manual. Familiarize yourself with the device’s features, functions, and operational guidelines.

Power on the Device:

  • Ensure the tester is adequately charged or connected to a power source. Power on the GAO Tek’s Water Quality Tester following the instructions in the user manual.

Select Testing Parameters:

  • Identify the specific water quality parameters you want to measure, such as pH, conductivity, dissolved oxygen, etc. Utilize the Water Quality Tester’s interface to select the appropriate testing mode.

Prepare the Sample:

  • Collect a representative water sample from the source you intend to test. Follow recommended sampling procedures provided by GAO Tek to ensure accurate and consistent results.

Submerge the Sensor:

  • Carefully submerge the GAO Tek’s sensor into the water sample. Position it according to the specified depth and orientation for accurate readings.

Record Measurements:

  • Allow the Water Quality Tester sufficient time to stabilize and record the measurements as instructed in the user manual. Take note of any specific considerations for each parameter.

 

Maintaining a Water Quality Tester:

Clean the Sensor:

  • Regularly clean the sensor of the Water Quality Tester to prevent residue buildup. Use a soft brush or cloth as recommended by GAO Tek to ensure accurate readings.

Store Properly:

  • When not in use, store the Water Quality Tester in the provided case or in a clean, dry environment. Protect it from extreme temperatures and direct sunlight.

Check Battery Status:

  • Monitor the battery level regularly and recharge or replace it as needed. Follow GAO Tek’s recommendations for battery maintenance to maximize the device’s lifespan.

Calibration Check:

  • Perform routine calibration checks using GAO Tek’s calibration solutions. Follow the calibration procedures outlined in the user manual to maintain measurement accuracy.

 

Calibrating a Water Quality Tester:

Gather Calibration Solutions:

  • Acquire GAO Tek’s recommended calibration solutions for each parameter. Ensure these solutions are within their expiration dates.

Access Calibration Mode:

  • Navigate through the Water Quality Tester’s menu to access the calibration mode. Follow the user manual to initiate the calibration process.

Immerse Sensor in Calibration Solution:

  • Submerge the sensor into the calibration solution for each parameter. Allow the readings to stabilize, and the device will prompt you to adjust if necessary.

Adjust Calibration Values:

  • If prompted, use the Water Quality Tester’s controls to adjust calibration values until the readings align with the known values of the calibration solutions.

Confirm Calibration:

  • Confirm and save the calibration settings as per GAO Tek’s instructions. Perform a final check using another set of calibration solutions to validate the accuracy of the calibration.
