  • Page 5: Application

    1. APPLICATION Meters of the N24 and N25 series are digital instruments destined for the measurement of d.c. voltage or d.c. current: uni or bipolar, temperature through J, K thermocouples, Pt100 resistance thermometers and for the measurement of a.c. voltage and a.c. current. A LED display (4 digits for N24 and 5 digits for N25 meter series) constitutes the readout field.

  • Page 6: Operational Safety

    · The programming of N24 and N25 meter series parameters must be carried out after disconnecting measuring circuits · Before switching the meter on, one must check the correctness of connections to the network.
