OM-PLCV: AC Current, AC Voltage Logger

The OM-PLCV data logger is a precision instrument for recording AC current and AC
voltage. AC current is sampled using the supplied clamp probe. The logger can store
up to 21,500 data points, when it is setup to record either AC current or AC voltage
(but not both). The logger can store up to 10,750 points, when it is setup to record
both AC current and AC voltage. Each logger is factory calibrated. This means that
the clamp probes are not interchangeable.

Connecting the OM-PLCV to Electrical Equipment

Before connecting to any equipment follow these precautions:

• Make sure that the wires are securely attached to the connector and that no
uninsulated portion of the wire is visible after the connection is made.

• Make sure that there is no strain that could pull the leads out of the OM-PLCV
connector.

•Make sure that the leads will not interfere with any moving pieces of equipment and
will not pull loose any wires or other connections.

To measure the voltage, connect the two voltage clip leads to the points at which the
voltage is being measured. To measure the current, place the clamp probe around one
of the conductors or wires in which the current is being measured.

CAUTION!

Electrical connection to any type of operating equipment is Dangerous! The
OM-PLCV leads and current probe should only be connected when it has been
determined that the power is off and the equipment is safe to touch. It is

recommended that you always remove the OM-PLCV voltage leads before
connecting the OM-PLCV to your computer!
