cont'd
Digital outputs are available on a 9 pole "D" connector to control external range selection and reference impedance insertion in integrated automatic test systems.
The specified main operating modes are: "Steady-state harmonics / Single-shot" (1 time-window), "Transitory harmonics / 2.5 minutes" measurements and data collection (469 time-windows at 50Hz or 563 at 60Hz), and "Continuous Mode" with full management of transitory harmonics and automatic stop when limits are exceeded. The collected data are stored in a circular buffer so that the last 2.5 minutes measurement data are available.
Voltage harmonics are continuously evaluated in order to check the power source during the measurement cycle, as required by IEC1000-3-2.
The voltage and current shapes, the amplitude of any harmonic versus time, as well as the real-time voltage and current spectra are available for monitoring on two analog outputs BNCs.
Automatic self-calibration procedures allow find adjustments for offset and gain, granting very accurate and stable measurements from 5mARMS to 16ARMS.
The fully compliant IEC868 Flicker measurement are based on two input channels fully auto-ranging in the range 40+504VRMS. This allows to simultaneously measure the EUT and check the power source (Pst,0.4). Two software selectable analog outputs allow the complete visual monitoring of significant signals such as "instantaneous flicker sensation" or "d(t) relative voltage change characteristic" for each channel. Flicker produced by fluctuating harmonics is correctly measured.
Self-test functions grant measurement correctness.
The IEEE-488 interface allows the B10 to be easily integrated into an automated test system and aids fast data transfer to a host PC. Its galvanic isolation is very useful in complete test systems to avoid ground loops.
