Description: Digital Power Analyzer
                                    Valhalla Scientific Models 2100 and 2101
Digital Wattmeters are accurate, low-cost In­
struments to aid engineering, production test and
quality assurance departments in the determina­
tion of product power consumption from DC and
AC power lines. The instruments feature dual, in­
dependent digital displays. One display provides a
continuous indication of True Power in Watts. The
other display is sw itch selectable between
Amperes (True RMS) and Volts (True RMS).
1-3 The Model 2100 and Model 2101 provide a fast
and convenient method of determining product ef­
ficiency, power factor and true RMS current. Phase
angle relationships may be calculated through
utilization of the displayed digital data.
1-4 The Digital Wattmeters use a unique four-
quadrant complex waveform analog m ultiplier to
derive a DC signal equivalent to the integrated pro­
duct of the instantaneous value of line voltage and
current. The resultant wattage value is converted
for presentation on a 4-1/2 digit display. Power
ranging provides maximum resolution from 10
m illiwatts to 12000 watts on the Model 2100 and
from 1 m illiw att to 6000 watts on the Model 2101.
True RMS current from 100 microamperes (max
resolution) through 19.99 amperes with a crest fac­
tor of 2.5:1 may be monitored by selecting the cur­
rent display with the front panel switch. True RMS
voltage from 7.5 volts to 600 volts may be
monitored on the Model 2100 by selecting the
voltage display. On the 2101, the range is from 1.5
volts to 300 volts. Four binding posts on the rear
panel provide convenient means of making the
measured line and load connections.
1-5 The Digital Wattmeters are designed to
operate from selectable 115/230V AC power. The
loads may be operated from power sources up to
600 volts on the Model 2100 and up to 300 volts on
the Model 2101. These sources may be indepen­
dent of instrument power and may be DC, or AC
from 40 Hz to 20 KHz. Peak voltage limitation is
1500 volts for the Model 2100 and 750 volts for the
Model 2101. There are three selectable current
display ranges identified on the front panel as .2,2
and 20 amperes. DC current may be displayed up
to 0.5000, 5.000 and 20.00 amperes. AC sinewave
current may be displayed up to 0.3500, 3.500 and
20.00 amperes. Voltage display ranges are also
selectable in three steps; 150.00, 300.0 and 600.0
on the Model 2100 and 30.00, 150.00 and 600.0 on
the Model 2101
