    1. GENERAL CHARACTERISTICS The HD32.7 RTD datalogger is an instrument that can capture, log and then send to a PC or serial printer the data coming from 8 temperature probes with Pt100 or Pt1000 sensor connected to the inputs. The probes can be Pt100 with SICRAM module, direct 4-wire Pt100 or direct 2-wire Pt1000. All the connected probes must be of the same type.

    Pt1000) is selected from the menu. (Please see the “Input” paragraph on page 22.) 2.1 The Display The HD32.7 standard display is divided in two areas: The first area displays the battery’s charge status and the current time (above); then, the temperatures measured by the probes connected to the inputs (below) arranged on two columns.
  • Page 8 NOTE: The non-connected inputs will be indicated by dashes. If a probe is disconnected when the instrument is on, the “LOST” message will be displayed in case of a SICRAM probe, or dashes in the other cases: Reconnect the probe to read the measured temperature. Do not connect the probes when the instrument is on: In order to correctly detect them, you need to turn the instrument off and then back on again.
  • Page 9 ENTER key In the menu, it confirms the entered data. ESC key It allows to exit from the menu or, in case of a submenu, to move up one level. MEM key It allows to start and end a “logging” session (data recording); the data logging interval must be set in the menu.
