    Introduction The DAS30, DAS50 and DAS60 programmable recorders measures and records voltage, current, temperature, etc. on up to 6 channels. The recorders also include digital input capabilities using the 12 logic input channels. An optional feature of the recorders is a port for measuring temperature with Pt100 or Pt1000 temperature sensors. 1.1 Recording Modes Finally, the optional thermal printer adds the ability to print recorded signals (saved and in real-time).
