Safety & Warnings
Every precaution has been taken in the design of the DVM36 digital multimeter to ensure safety, but safe operation depends on the operator. The following safety precautions are explicitly mentioned:
1. Never exceed the instrument’s limits as specified in the manual.
2. A severe shock hazard can occur if the equipment chassis is connected to the “hot” side of the AC line. Always use an isolation transformer and ensure the workbench and floor are dry and non-conductive.
3. Remove circuit power before making connections to high voltage points. If this is not possible, avoid contact with other equipment or metal objects, keep one hand in your pocket, and stand on an insulated floor mat to reduce shock risk.
4. Discharge filter capacitors before connecting test leads.
5. Ensure equipment is in good condition; broken or frayed test leads can be dangerous.
6. Remove test leads immediately after testing to reduce shock risk.
7. Do not work alone on hazardous circuits; always have another person nearby in case of an accident. Even a minor shock can lead to a more serious accident.
