1.2 Features
(1) Safe design
The 3193 POWER HiTESTER features a safe design that complies with the
IEC61010-1 safety standard.
(2) Capable of measuring power on all types of power lines
This single power meter is capable of measuring power on all types of power
lines, ranging from single-phase lines to three-phase four-wire lines by
installing the input units.
(3) Simultaneous measurement of multiple systems
Up to six input channels can be installed, so that for example, a single unit
can simultaneously measure the input power and output power of a three-
phase inverter.
By combinations with the optional external input units, the input power and
output power of an inverter and the output of a motor can be measured and
calculated with a single unit. Further, by using the efficiency calculation
function, the efficiency and overall efficiency of up to three points can be
measured simultaneously with one unit.
(4) Wide current measurement range
With a direct connection input unit, and no external current transformer, it is
possible to measure a maximum of 50 A rms. The internal current
transformer design keeps the losses in the current measurement meter
extremely low. Using a current sensor input unit, existing current sensors can
be used to measure up to 500 A.
(5) High accuracy
The basic accuracy of
±
0.1% rdg.
±
0.1%f.s. is high.
(6) Wide frequency range: DC and 0.5 Hz to 1 MHz (using optional
9600
AC/DC DIRECT INPUT UNIT
)
The wide frequency response supports the evaluation of inverter-motor
systems, inverter fluorescent lighting systems, ultrasound motors, switching
power supplies, and so on.
(7) Built-in low pass filter
The cut-off frequency can be selected from three values. This function allows
an inverter fundamental frequency to be extracted, and also supports data
exchange with conventional devices.
(8) Three types of calculation expression selectable
Three types of calculation for apparent power and reactive power can be
selected, to support compatibility with conventional devices.
