The main functions are the sourcing of mV or mA signals, resistance and simulation of DIN-thermocouples and RTD temperature sensors. Up to eight fast input signals -Transients- can be measured, memorized and shown at the display as graphs or uploaded to a PC via USB. For fast checking or calibration of process transmitters the M505 output and input can be cross connected to the transmitter, whereas both sourced and measured signals will be displayed online. mV voltage ranges are useful for calibration of strain gauges, amplifiers, transmitters and small signal instruments, where the output voltage can be resolved down to 1 uV.

Transients: Eight memory slots are available for storing of fast signals at the multimeter input. Each transient ca individually be shown on LCD display.
