3193 POWER HiTESTER - Wide spectrum power meter for comprehensive device assessment
A multi-function power meter for use with single phase power lines to 3-phase, 4-wire circuits. Accommodating up to 6 units, the unit is not only capable of measuring up to 6 single phase systems, but can simultaneously measure the input and output of a 3-phase inverter and provide effective power measurements. Additionally, it supports harmonic analysis and flicker measurement (optional), features which are essential for overall device assessment.

-   Measurement lines : 
Single-phase/two-wires to three-phase/four-wires (Through the use of various input units)
-   Measurement items : 
(When using 9600, 9601, 9602, optional)
Voltage, current, voltage/current peak, effective/reactive/apparent power, power factor, phase, frequency, current/power integration, load rate, efficiency
(When using 9603, optional)
Voltage, torque, RPM, frequency, motor output
(When using 9605, optional)
Harmonic, waveform, voltage fluctuation / flicker measurement function
-   Measurement ranges : 
Voltage: 6.0000 V to 1.0000 kV (depends on use of the input unit)
Current: 200.00 mA to 500.00 A (depends on use of the input unit)
Power: Depends on combination of voltage and current ranges
-   Integration range : 0 to ±999999 TAh/ TWh, (integration time up to 10000 hours)
-   Basic accuracy (used with 9600 to 9602 Input unit) : ±0.1% rdg. ±0.1% f.s. (voltage, current, power, at 45 to 66Hz)
(Note: When used together with the 9270 to 9272, and 9277 to 9279, resulting accuracy is the sum of that indicated above and the accuracy of these clamp sensors)
-  Frequency characteristics : 
used with 9600: DC, 0.5 Hz to 1 MHz
used with 9601: 5 Hz to 100 kHz
used with 9602: DC, 0.5 Hz to 200 kHz (depends on the clamp accuracy)
-   Signal output: 
Analog level: Voltage, current, active power, 5 V DC f.s.
Waveform monitor: Voltage, current, 1 V rms f.s.
D/A output: Outputs 8 arbitrarily selected items, DC±5 V f.s.
-   Other functions: 
6.4 inch TFT color LCD, RMS/MEAN rectification, FDD,
GP-IB/RS-232C interface, scaling, averaging
-   Power supply : 100/120/200/230 V AC (switched automatically), 50/60 Hz
