welldana Check Kit Moicro Salt

Product Usage Instructions

• Measurement of the Parameters:
  • Carefully pull off the protective cap and rinse the electrode.
  • Select conductivity mode (COND).
  • Immerse the electrode in the recommended calibration solution.
  • Press and hold for 3 seconds until the screen turns green (Calibration mode).
  • Stir the tester briefly and wait for the calibration value to stabilize.
  • Press and hold for 1 second to start calibration.
• Changing Between Measurement Modes:
  • To change between conductivity (COND), TDS, and salinity (SAL) modes for new measurements, follow these steps:
  • Press the designated key to switch between modes.
  • Ensure the measuring range and resolution settings are appropriate for the desired mode.
• Replacing Batteries:
  • To replace the batteries, follow these steps:
  • Open the battery cover and remove the old batteries.
  • Insert four AAA batteries, ensuring the positive terminals face up.
  • Close the battery cover securely to maintain water tightness.

FAQs

• Error Messages and Resolutions:
  • Err 1: Reason: Old calibration. Procedure: Use new calibration solutions.
  • Err 2: Reason: Key pressed too early. Procedure: Wait for the appropriate time before pressing the key.
  • Contamination/Error Fluctuations: Procedure: Clean the electrode with detergent, and rinse with deionized water (avoid rubbing black pins).

Measurement of the parameters

Note:

• Change between conductivity (COND), TDS, and salinity (SAL)
• Press “Hold“ for new measurement recording.

Calibration conductivity

Note:

• Recommendation: 1-point calibration depending on the measuring range.

After successful 1, 2 or 3-point calibration, is shown on the display:

Note: 1000 μS/cm = 1 mS/cm
