Features

  • Unit of measurement °C, °F, °K configurable.
  • Flash memory organized in 64 sections with a total capacity of 96.000 acquisitions for each one of the 8 inputs.
  • Storage can be managed in two ways:when the available memory is full, data are overwritten by starting from the oldest ones (circular memory),
  • storage stops when the available memory is full.
  • Simultaneous display of the 8 inputs.
  • Maximum, minimum or average of the stored values.
  • Selectable storage interval: 2, 5, 10, 15, 30 seconds, 1, 2, 5, 10, 15, 20, 30 minutes and 1 hour.
  • Data logging: instantaneous or postponed, with the possibility of selecting the storage start and end.
  • Data download: RS232C, 1200…38400 baud or USB 1.1 – 2.0.
  • DeltaLog9 software for data download and processing.
  • LCD backlit graphic display 128×64 pixel.
  • Instrument setup through the keyboard; no connection required to the PC.
  • Security password for keyboard locking.
  • Power supply: 4 1.5V alkaline C-BABY type batteries or external power supply 12VDC-1A.
  • Consumption @6VDC:
  • <60μA when the instrument is off
  • <60μA in sleep mode with 8 probes connected
  • <40mA during data logging with 8 probes connected
