1.9 Internal jumpers
Internal jumpers ‘S’ are associated to the signal range. The posion of
internal jumper ‘T’ assigns the funcon of the mulfuncon terminal
5. At ‘Table 2’ see a list of signal ranges and associated jumper ‘S’
and ‘T’. At Table 3 see the posion for jumper ‘T’ associated to each
funcon of the mulfuncon terminal 5. To access the internal
jumpers, open the housing as explained at secon 1.25. For addional
informaon on each signal range see the following secons :
• Ranges for AC voltages and currents, see secon 1.10
• Ranges for DC voltages and currents, see secon 1.11
• Ranges for thermocouples, see secon 1.12
• Ranges for Pt and Ni probes, see secon 1.13
• Ranges for NTC probes, see secon 1.14
• Ranges for PTC probes, see secon 1.15
• Ranges for process signals, see secon 1.16
• Ranges for frequency signals, see secon 1.17
• Ranges for resistance measures, see secon 1.18
• Ranges for potenometer measures, see secon 1.19
