Fax: [phone]; Website: www.chkpowerquality.com.au
Connect the appropriate voltage lead to the Miro. The voltage connector is keyed. Screw up
the locking ring to ensure the connector does not inadvertently become disconnected.
Connect the appropriate current probes to the Miro. These connectors are keyed. Screw on
the locking rings to ensure that the connectors do not become inadvertently disconnected.
When any voltage clamp/plug is connected to a hazardous live conductor, the other voltage
clamp/plugs should also be treated as live, due to the internal measurement impedance of
the Miro.
When attaching the connectors to the Miro, ensure the connectors and receptacles on the
Miro are completely dry.
To ensure accurate power measurements, it is important that the current probes are
connected to the same phases as the voltage leads. For example, the A phase voltage must
be measured by the A phase voltage clamp and the A phase current probe must measure
the A phase current. Current probe arrows should point to the load to ensure accurate power
measurement.
Connect the current probes first, making sure that:
They are connected to the appropriate phase; and
The arrow markings point towards the load.
