4. Operating Instructions

This section outlines the basic operation of the PC700 Meter.

4.1 Powering On/Off

• Press the POWER button to turn the meter on.
• Press and hold the POWER button to turn the meter off.

4.2 Mode Selection

The PC700 meter can measure pH, mV, conductivity, TDS, and temperature. Use the dedicated mode buttons (e.g., pH/mV, COND/TDS) to switch between measurement parameters.

4.3 Calibration

Accurate measurements require proper calibration. The PC700 supports up to 6-point pH calibration and conductivity cell constant entry.

• pH Calibration: The meter features auto-buffer recognition for USA (1.68, 4.01, 7.00, 10.01, 12.45) and NIST (1.68, 4.01, 6.18, 9.86, 12.45) buffer sets. Refer to the quick reference card for detailed calibration steps.
• Conductivity Calibration: Calibrate using standard solutions. The meter stores conductivity/TDS cell constants (0.1, 1.0, and 10).

4.4 Temperature Compensation

The meter offers automatic (ATC) or manual temperature compensation (MTC). Temperature can be displayed in either degrees Fahrenheit (°F) or Celsius (°C).

4.5 Data Storage and Retrieval

The PC700 can store up to 100 data sets. Use the MEM button to store readings and the RECALL function to retrieve stored data.

4.6 Display Hold

Press the HOLD button to freeze the current reading on the display for easier recording.

5. Maintenance

Proper maintenance ensures the longevity and accuracy of your PC700 Meter.

• Cleaning the Meter: Wipe the meter's exterior with a damp cloth. Avoid abrasive cleaners or solvents. Ensure the membrane keypad is kept clean.
• Electrode Care:
  • Always keep the pH electrode bulb hydrated in storage solution when not in use. Never store in distilled water.
  • Rinse probes with distilled water after each use to prevent sample contamination and buildup.
  • Inspect probes regularly for damage or buildup. Clean as necessary using appropriate cleaning solutions recommended by the manufacturer.
• Storage: Store the meter and probes in a clean, dry environment away from extreme temperatures and direct sunlight.
