Important Safety Precautions ❗
Special attention must be paid when using test and measurement instruments, as improper usage can lead to electric shock and equipment damage.
- Always use probes, test leads, and adapters with the proper measurement category (CAT), voltage, and amperage ratings for your measurement.
- Do not use or store the device in environments with explosive gas, vapor, or under high temperature and humidity.
- When handling test probes and crocodile clips, keep your fingers behind the physical guard.
- Before use, examine the measuring test leads. If any part of the insulation is deteriorated, replace them with proper functional test leads.
- When connecting test leads, connect the common lead before the live test lead, and remove the live test lead before the common lead.
- Before measuring current, ensure the instrument has available fuses and disconnect the power supply to the circuit being tested.
- Remove batteries if the device is not used for an extended period or stored in temperatures above 45°C to prevent battery leakage and damage.
