MASTECH MS7222 RTD Calibrator Instruction Manual

1. Sarrera

The MASTECH MS7222 RTD Calibrator is a specialized tool designed for the calibration of Resistance Temperature Detector (RTD) transmitters, including those with pulsed outputs. This instrument is capable of both simulating and measuring seven distinct types of RTDs, with readings displayed in either Celsius (°C) or Fahrenheit (°F), as well as resistance in ohms. It is important to note that the MS7222 cannot simultaneously function as a source and a measurement tool.
