CAUTION!
MPU-1 signaler is designed to measure the current flowing through conductors with
voltages up to 1000V.
Connecting voltages higher than 25V between any of the test terminals may damage the
device.
7 Measuring socket [Probe (1) / Charger]
To connect a single Sonel F-Series Rogowski-type current probe. Used for measurements with a
single probe. The battery charger also connects to this socket; it has the same pronged connector.
Unused socket should be covered with the flexible socket cover.
8 Measuring [Probe (2)]
To connect a second Sonel F-Series Rogowski-type current probe. Used for measurements with a
two probes. Unused socket should be covered with the flexible socket cover.
When using two probes the MPU-1 mathematically sums up the current values from the two probes
and does not take into account any phase shifts.
