1. The DET series instruments require very little maintenance.
2. Test leads should be checked before use to ensure there is no damage.
3. Ensure batteries are removed if left unused for extended periods.
4. When necessary, the instrument can be cleaned with a damp cloth.
5. Do not use alcohol-based cleaners, as these may leave a residue.
