Safety Instructions:

1. Do not measure voltages or currents in damp or wet environments.
2. Do not use the measuring device in environments containing explosive or flammable gas, materials, vapor, or dust.
3. Do not touch the circuit under measurement when no measurement is being performed.
4. Avoid touching exposed metal parts, unused measurement terminals, etc.
5. Do not perform measurements if you notice any irregularities such as deformations, cracks, leaking substances, or a non-functional display on the measuring device.
6. Exercise special caution due to the risk of electric shock when measuring voltages above 25 V in special environments (courtyards, swimming pools, etc.) and above 50 V in normal environments.
7. Use only original HT accessories.
