Getting Started

The PCTSTestr 50 Pocket Tester has been factory calibrated and usually works well out of the box. However, after extended periods of non-use, it is best to remove the sensor cap and soak the sensor in warm tap water for 10 minutes or so. Prior to taking the measurements, periodic calibration with certified standards is recommended for best accuracy.

pH Calibration

Calibration should be done regularly, recommended once a week. Calibrate up to three points using either the USA or the NIST buffer set standards.

1.Press ON/OFF () to power on the tester if needed.

2.Dip electrode about 2 cm to 3 cm into the pH standard buffer solution.

3.Stir gently and press CAL/ESC to enter calibration mode. The CAL indicator will be displayed. The upper display will show the measured reading based on the last calibration while the lower display will indicate the pH standard buffer solution.

Note: To abort calibration, press CAL/ESC to escape.

4.Allow about 2 minutes for the tester reading to stabilize. The timer icon blinks during this time. Once the reading is stabilized, the timer stops blinking. Automatic confirmation happens when the buffer is found and

the display returned to measurement window with reading calibrated to pH standard buffer solution.

5.Repeat with other buffers if necessary. Rinse electrode before dipping into next buffer.

Note: The calibration mode allows you to perform up to three calibration points. Calibration is automatically confirmed with the buffer identification. No user interaction is required after starting the calibration by pressing CAL/ESC.

Calibration for Conductivity, TDS, or Salinity

For best results, periodic calibration with an accurate standard is recommended prior to measurement. Use the calibration standard value that is close to your intended sample value. The tester will retain one calibration value in each mode (conductivity, TDS, salinity) when the instrument is powered off. The conductivity value can be calibrated automatically or manually, while the TDS & salinity values require manual calibration. The tester will begin in the measurement mode that was used when it was powered off. See “Measurement Parameter Setting” to change the desired parameter.

Automatic Calibration for Conductivity

1.Remove the cap and press ON/OFF () to power on.

2.Dip the sensor in at least 30 mm of calibration standard.

3.Stir gently and press CAL/ESC to begin the calibration.

4.The display will show CAL followed by the default value. CAL is indicated on the display during calibration mode.

5.If the reading is within the calibration range of the automatically recognized standards; 80 (84 μS/cm), 1410 (1413 μS/cm),

or 12.90 (12.88 mS/cm), the icon is displayed when the automatic calibration standard value has been detected.

6.Press HOLD/ to accept the auto conductivity standard and finish the calibration.

7.Display returns to Measurement window.

Manual Calibration

When the conductivity reading is outside calibration range of the automatic conductivity standards or when TDS or salinity is used, the tester will require manual adjustment.

1.Repeat steps 1 to 4 from “Automatic Calibration for Conductivity”.

2.Press MENU/v to manually adjust the value to the desired reading.

Note: The adjustment will decrease only, however the adjustment will eventually cycle to the highest available value after decreasing by 40% of the initial value.

3.Press HOLD/ to accept and finish the calibration when the desired value is selected.

Note: To abort calibration, press CAL/ESC to escape.
