GENERAL INFORMATION
DESCRIPTION :
Vector model 1522 Digital Wattmeter is an accurate low
cost instrument designed for use in Engneering, Quality
control and Production Test departments to determine the
power consumption of equipments operating directly from
a standard 110 - 150V AC, 60Hz line. Instrument features
large L.E.D. display.
In addition to power measurement, the wattmeter
measures AC (true RMS) voltage and AC (true RMS)
current.
The Digital Wattemeter is easy to operate. Each
measurement function, voltage (V), current (I) or power
(W) is selected by a simple pushbutton switch on the front
panel.
The Digital Wattmeter can be connected to two different
loads. The total load current can be upto 20A maximum.
