Introduction Thank you for selecting the PCE-PWT 10 pocket salinity tester. This manual provides a step-by- step guide to help you operate the meter, please carefully read the following instructions before use. The following list describes the standard accessories of the tester. After unpacking, please check that all accessories are complete.
Display The tester is equipped with a clear LCD display that is used to show measured value, mode indicators and unit indicators. ppm ppt INDICATOR DESCRIPTION MEAS Indicates tester is in the measurement mode Indicates tester is in the calibration mode SETUP Indicates tester is in SETUP mode HOLD...
Power On/Off ● Press MEAS key to turn on the tester, the display shows measured value. ● Press and hold the MEAS key for 5 seconds, the tester will turn off. ● If you do not press any key for 8 minutes, the tester will automatically turn off to conserve energy.
Setting the Default Parameters Press and hold the CAL key for 3 seconds to enter setup menu, the tester shows current selected number of calibration points. Press CAL key again to select 1, 2 or 3 point calibration and press ENTER key to confirm. The tester goes to temperature unit selection mode, the display shows “...
Press CAL key to set temperature value and press ENTER key to confirm. The tester shows “YES/HOLD” indicating that the auto-hold function is enabled. Enter If the auto-hold function is enabled, the tester will automatically sense a stable endpoint reading and freeze it. If you disable this function, the tester allows the user to freeze the reading by pressing the HOLD key.
Conductivity Calibration PCE-PWT 10 pocket salinity tester allows up to 3 points calibration in the conductivity mode. To ensure higher accuracy, we recommend that you perform 3 points calibration or select a standard value close to the sample value you are measuring. The tester will automatically detect these conductivity standard solutions and prompt the user to calibrate the meter.
Single Point Calibration Rinse the conductivity electrode with distilled water, then rinse with a small amount of calibration solution. Press CAL key, the tester enters the calibration mode. Dip the conductivity electrode into the calibration solution, the tester immediately shows current calibration standard (e.g., 1413µS/cm).
2 Point Calibration Make sure that you have selected 2 points calibration in the setup menu. Repeat steps 1.2 to 1.6 above, when the first calibration point is done, the display will show “CAL2”. The tester prompts you to continue with second point calibration. Dip the electrode into the calibration solution, the tester automatically shows current calibration standard (e.g., 12.88mS/cm).
3 Point Calibration If you have selected 3 points calibration in the setup menu, when second calibration point is done, the display will immediately show “CAL3”. The tester prompts you to continue with third point calibration. Repeat the above steps until the display shows “END”, the tester returns to measurement mode.
Wait for the reading to stabilize and record the measured value on the display. Hold Function PCE-PWT 10 pocket salinity tester contains two data hold modes. When the Auto-Hold function is enabled, the tester will automatically sense a stable endpoint reading and freeze it, “HOLD”...
Electrode Replacement When the tester fails to calibrate or gives fluctuating readings for calibration standards, you will need to replace the electrode module. Twist the electrode collar counter clockwise, pull the old electrode module away from the tester. Align the slot on the new electrode module, gently push the module into the tester. Twist the electrode collar clockwise until it is tight.
