Universal Calibrator UniCal 38534

The Universal Calibrator (UniCal 38534) is a micro-controller based portable, battery-operated, precision instrument designed for sourcing and measuring Ohm, RTD, mA, mV, T/C and V signals. A graphical (128x64) LCD with backlight gives excellent user interface. It is designed to calibrate a broad spectrum of instruments and retain its precision and repeatability over long periods in worst environmental conditions. An exceptionally stable voltage/current source provides continuously variable precision output signals with two ten-turn potentiometers.

Features

  • Sources & measures Ohms, RTDs, mA, mV, TCs, V
  • High precision, accuracy, reliability & longevity
  • Graphical(128x64) LCD with backlight for excellent UI
  • Simultaneous display of temperature & mV or Ohms
  • Auto or Manual cold junction compensation (CJC)
  • Continuous indication of cold junction temperature
  • Compact in size and built for toughest environments
  • Unique self-check facility ensures reliable operations
  • Powered by AC/DC adapter or 6 AA Ni-Mh batteries

Application

  • Powers (24VDC) & calibrates 2-wire transmitter
  • Simulates transmitter (with 24VDC loop power)
  • Simulates & measures T/Cs with Auto/Manual CJC
  • Simulates & measures multiple RTDs
  • Works as voltage and current regulator or source
  • Powers (24VDC) and calibrates control valve positioner
  • Calibrates various temperature and process indicators
