The DP2000/DP9000 AC AVG voltmeter and ammeter
use a precision op-amp rectifier circuit to provide an
economical AC-average meter, which is calibrated to
display the true-RMS value of sinusoidal signals.
The AC RMS voltmeter and ammeter use an integrated
circuit that computes the true-root-mean-square value
of complex waveforms.
Screw-terminals are provided for AC or DC coupling.
AC coupling allows the measurement of the AC
component or ripple from a signal with both AC and DC
components. DC coupling allows the measurement of
true-RMS, including both DC and AC components.
The signal conditioner provides six current ranges, as
determined by an internal shunt resistor. In addition,
there is a special 5 A range, which allows direct
connection to a current transformer (CT) with 5 A
secondary, without need for a stepdown transformer.
Proper scaling can be for any primary current.
An 1/8 DIN case houses each meter. Choose any
combination of display type (LED or LCD), operating
power, input type and range, analog output, and digital
or control outputs.
