Extech 380405 Capacitance Decade Box lets you try values quickly in a live circuit. You swap it in place of a capacitor and find the sweet spot with ease.
Circuit tuning made simple
You dial through small step changes and watch how the circuit behaves. You then note the setting and choose a fixed part with confidence.
Clear readout and safe testing
Switch settings show the value directly so you avoid mental conversion. The DC limit keeps testing within a safe working range.
This decade box helps with product design checks and calibration tasks in the lab. It also supports quick teaching demos and troubleshooting on the bench.
Key features
- Works as a direct substitution component in-circuit
- Lets you trial values step by step for fine tuning
- Helps you read the chosen value straight from the switches
- Speeds up design experiments and calibration routines
- Aids fault-finding by comparing behaviour at different values
- Supports non-polarised capacitor testing in DC circuits
- Reduces calculation mistakes with clear front-panel settings
- Useful for labs, workshops and education environments
- Encourages repeatable tests with consistent step changes
- Saves time selecting a permanent capacitor for final builds
- Suits quick demos where rapid value changes are needed
- Keeps workflows simple with a single compact unit
