d) 15 year designed life

e) Balance alarm can be set by user according to his own need

Safety precautions:
- Use only isolated tools.
- Do not connect the meter to a 3 phase - 415V AC - network.
- Place the meter only in dry surroundings.
- Make sure the used wires are suitable for the max current the meter can measure.
- Make sure the AC wires are installed correctly before activating the current/voltage.
- Do not touch the meter connecting clamps directly with your bare hands, with metal, blank wire or other material as you will have the chance of an electricity shock and a possible chance for health damage.
