Operating the Testmaster-Pro: Best Practices

Operating the Testmaster-Pro requires a blend of technical know-how and a keen sense of safety. While the equipment is designed for efficiency, it’s essential to approach its operation with care and diligence. The following best practices ensure that users can achieve optimal results while prioritizing safety.


  1. Place the material to be tested on an insulating surface or ensure it’s properly grounded.
  2. Never hold the sample in your hand during testing.
  3. Handle the probe by its handle, avoiding the front end.
  4. For multiple test samples, place them on insulating surfaces or attach a proper ground connection.
  5. Ensure no one touches the material being analyzed during testing.
  6. Press the START button with the probe against the material and wait for the completion of the measuring cycle.

General Guidelines

General Guidelines for Safe Operation

While the Testmaster-Pro is a marvel of engineering, it’s crucial to remember that like all machinery, it demands respect and understanding. These general guidelines are designed to ensure that the equipment is used safely and efficiently, minimizing risks and maximizing its lifespan.


  1. Consider installing a password in the software to prevent unauthorized access.
  2. Always turn off the source (using the red pushbutton) during maintenance, cleaning, or adjustments.
  3. If the Testmaster-Pro isn’t in use for more than 5 minutes, turn off the source.
  4. Never leave the Testmaster-Pro unattended without turning it off.
  5. For added security, consider removing the probe and storing it safely, especially if points 7-10 aren’t feasible.
  6. Avoid over-sharpening the electrode. If it becomes too short, it might break the ceramic.
  7. Never modify the electrode set screw to avoid electrical shorts and damage to insulating bodies.
