M505 Process Calibrator

Handheld calibrator-multimeter of industrial process signals including voltage, current, resistance and temperature. External signals up to 200 V or 100 mA can be measured simultaneously with signal sourcing.

• Handheld calibrator and multimeter
• 1 ms sampling feature
• Datalogger option

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.

Datalogger (Option): The generated calibrator signal and the measured signal at the multimeter input will be stored as tables with date and time added. The interval is selectable from 2 sec. to 24h. The data can be transferred to a PC, shown as tables and graphics and handled under Windows and Excel.

Transients: Eight memory slots are available for storing of fast signals at the multimeter input. Each transient ca individually be shown at the LCD display and optional transferred to a PC, shown as tables and graphics and handled under Windows and Excel.
