Multifunction calibrator PROVA iCal

temperaturevoltagecurrent

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.
