Method of use

Setup

1. Connect the headphones
2. Turn on the instrument
3. Adjust the sensitivity
4. Begin scanning

Scanning

• Slow movement — of the detector across the object
• Proximity — moving closer to the source
• Level change — determining direction

Interpretation

• Continuous sound — leak or defect
• Cyclical sound — mechanical equipment
• Silence — normal condition

When to choose the SDT200

Ideal for

• Small facilities — limited budget
• Beginner programmes — learning ultrasound testing
• Specific tasks — a single application
• Operators — simple checks

Limitations

• No memory — cannot record data
• No spectrum — listening only
• No trends — cannot track changes over time
