    1. GENERAL CHARACTERISTICS The HD32.8.8 and HD32.8.16 are two dataloggers for thermocouples that can capture, log and then send to a PC or serial printer the data coming from the 8 or 16 thermocouples. The instruments can work with thermocouple of type K, J, T, N, R, S, B or E. During the measuring phase, the connected probes must be of the same type.

  • Page 7: Keyboard And Display Description

    The probes are displayed in groups of four, according to the order of the connectors from left to right: From input A1 to input B4 in the HD32.8.8 model, and from input A1 to input D4 in the HD32.8.16 model. The unused inputs are not shown in the list.
