WT1800 POWER ANALYZER PRODUCT TUTORIAL
A.) OVERVIEW & OBJECTIVES
The following is a basic demo procedure for the WT1800 Power Analyzer. This demo uses
the power meter’s own power supply for the load. The demo can easily be done in a
conference room or lab without having to hook up to the customer’s load.
B.) POWER METER CONNECTION
Measuring consumption power of the WT1800 Power analyzer
1. Connect the Power Meter using the load cord. Plug the Banana plugs into the Voltage
input terminals of Element # 1. Connect the Spade lugs to the Current terminals of
element # 1. Make sure all connections are tight.
2. Plug the power meter power cord into the load cord. Plug in the load cord.
3. Turn on the power meter.
Connect to 120 V 60
Hz Power Source
Plug Power Cord from
WT1800 Power Analyzer
into Load Cord.
Plug the Banana plugs into the Voltage
input terminals.
Connect the Spade lugs to the Current
terminals.
