Documenting Multifunction Calibrator and Arbitrary Function Generator

  • Unique mapping function let you calibrate temperature (300 °C) or voltage (220V) directly.
  • iCal is a multifunction calibrator and an arbitrary function generator.
  • Source: mA (4 to 20mA), V (0 to 15V, 0 to 70mV), Hz, sine wave, square wave, triangular wave, truncated sine wave, user programmable waveform and temperature for 11 types of thermocouples.
  • Measure: current (mA), voltage (V, mV) and temperature (℃ or °F).
  • Programmable cold junction compensation allows users to fine tune temperature output and measurement.
  • Programmable 0% and 100% value for easy 25% step function.
  • Output error warning when output is shorted or open.
  • Short circuit protection for voltage output.
  • Clear and easy user interface (numerical key pad, sliding switch and dot matrix LCM with backlight).
  • Voltage, frequency, PWM duty-cycle (square wave and triangular wave), and offset are programmable in the Hz function.
  • Frequency range (0.3Hz to 20KHz) covers application of audio band (speaker, MP3, MD etc.)
  • DTMF (Dual Tone Multi-Frequency) can perform professional testing for telephone line and audio product (MP3 or MD).
  • Auto-step and auto-ramp functions can quickly perform linear test.
  • PC can program calibrator through USB port.
  • Data logging with programmable sampling time (0~255 sec.) and memory of 4000 records.
  • Rechargeable lithium battery (1600mAH) with built-in charging circuit.
  • Calibration results (source & measure) can be saved in memory (2000 records). Then users download them to a PC for documentation.
  • To distinguish calibration data at different locations, data can be saved under different file names.
