Product Overview

LCV: AC Current, AC Voltage Logger
The LCV 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 LCV 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 LCV 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 LCV 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 LCV voltage leads before connecting
the LCV to your computer!
The LCV Current & Voltage Data Logger measures external
Single Phase Current and Voltage, simultaneously
(Use 3 LCV’s to measure 3 Phase Current and Voltage.)
