One-shot Results for Narrowband, Full Spectrum and Harmonics


Measurement Channels
  • Outstanding accuracy of 0.015% of measured value + 0.01% of range
  • Full dynamic range of 500 µA to 32 A / 3 mV to 1000 V per channel available in single instrument
  • Power measurements from standby to full load (max. 32 A) without mechanical changes
  • Analog bandwidth DC up to 10 MHz
  • Modular configuration with 1 to 7 power measurement channels (alternatively 6 channels + 1 I/O card)
  • Gapless sampling up to 18 bit and a minimal cycle time of 30 ms
  • Delay time between V and I input < 3ns, very precise measurements at small power factors (PF) and/or high frequencies
  • Simultaneous measurement of narrow- and broadband values through innovative DualPath architecture
  • Simultaneous capturing of fundamental frequency and broadband RMS values for instantaneous detection of losses, resp. high-frequency components
  • Harmonics and interharmonics up to 2000. order, as required by EN61000-4-7
  • With optional I/O card speed/torque inputs freely configurable for all signal types (analogue, frequency as RS422,TTL or HTL) via menu
  • Flexible scripting tool for custom applications
  • Simultaneous measurement of V, I, P values and harmonics, presentation in tabular or graphical form
  • Signal filters freely configurable by frequency, type and characteristics
  • Synchronization to up to 7 different frequencies simultaneously
  • Flicker measurement, interactions between grid and appliance according to EN61000-4-15
  • Large and clearly arranged touchscreen GUI for intuitive handling
  • All instrument features displayed, identical look-and-feel for local and remote operation for quick and easy familiarization
Memory and Interfaces
  • Internal storage of long-term measurements even with shortest cycle-time thanks to integrated mass storage device
  • Excellent connectivity via USB2.0, Gbit-LAN, RS-232 and DVI/VGA
  • Convenient “plug-and-measure” through automated sensor detection
  • no external sensor power supply required
  • 12 months guaranteed calibration interval for minimal service cost and optimal availability
  • Calibration certificate included free-of-charge in first delivery
  • 24 months warranty
