The mean battery life is:
„ MA110 single‑phase
300 h in continuous operation
„
1,800 10‑minute measurements
„
„ MA130 three‑phase
500 h in continuous operation
„
3,000 10‑minute measurements
„
When the device is not connected to line power and the green On indicator goes off, the batteries must
be replaced (see § 4.2).
3.6.2. MAINS ADAPTER (OPTION)
The device can be powered by a standard mains adapter (5 V
