IWATSU VOAC22 Handheld Multimeter Iwatsu Digital Multimeter

Model：VOAC22 Country of Origin：Japan

Category：Digital Multimeter DMM

Overview：

Handheld Digital Multimeter. Conventionally, calibration adjustments required removing the case and adjusting potentiometers. The VOAC22 enables simple, reliable adjustment through front-panel key operations. It also enables one-touch calibration of AC voltage and AC current frequency characteristics, which was previously impossible. To prevent incorrect setup of measurement functions and terminals due to operating errors, a terminal shutter is provided at the current terminal section, and the terminal shutter opens and closes automatically in conjunction with the function switch.

・Peak hold function (for DCV/DCA)
  Supports waveforms of 250μs or more. Captures instantaneous peak values that ordinary maximum value measurement cannot catch.

・Duty ratio (%) measurement
Displays the duty ratio of square waveforms.
  (High-level period / 1 waveform cycle) × 100% = (t2/t1) × 100%
  Duty ratio measurement and frequency measurement enable calculation of high-level (t2) time.

・Comprehensive display functions
  (1) 50000 count & 51-segment bar graph display
  (2) Backlight standard-equipped, suitable for working in dark locations
  (3) Dual display shows "frequency and voltage" and "frequency and duty ratio"
    Simultaneous display such as "decibels and voltage" is possible

※The sub-display also shows the reference value for deviation calculation, the memory save number of measurement data, the recording time of maximum/minimum/average values, and the reference resistance for decibel calculation.
