2. Tindakan Pencegahan Keamanan

2.1 Keamanan Listrik

Before connecting the power cord, verify that the supply voltage is between AC 100 V and 240 V, with a frequency of 50 Hz or 60 Hz. You must use a three-prong outlet with a protective ground, and the protective ground resistance must be ≤4 Ω. Never cut or disconnect the protective ground wire, as doing so poses a risk of electric shock.

2.2 Keselamatan Lingkungan

Do not use in environments with flammable or explosive substances, strong electromagnetic interference, high temperatures and humidity, or excessive dust levels. Operating environment: Temperature 5°C to 35°C, relative humidity ≤ 65% RH.

2.3 Keselamatan Operasional

Before wiring, the power to both the meter and the device under test must be turned off; wiring while the circuit is energized is strictly prohibited. Connect voltage wires in parallel and current wires in series; under no circumstances should a current circuit be connected to a voltage terminal or a voltage circuit to a current terminal. After wiring, tighten the terminals and ensure that no bare wires are exposed to prevent short circuits or electric shock.

Do not apply voltages or currents that exceed the rated range.
