  • Measurement of voltage or d.c. current and temperature (Pt100, J, K):
  • Three-colour LED display (5 digits, 14 mm high).
  • 2 alarm outputs of OC type.
  • Galvanic separati on between the supply, measuring inputs and the programmer input.
  • Programmable parameters through the PD14 programmer: – recounti ng of indicati ons (individual characteristi c), – two alarms of OC type operati ng in 6 working modes, – display colour programmable in three intervals, – thresholds of displayed overfl ows, – highlight of the unit, – automati c or manual compensati on: temperature of cold ends (for J, K) or wire resistance (for Pt100), – measurement averaging ti me.
  • Supply of object transducers.
