Simultaneously Source and Measure. Voltage, Pulse, Current, Resistance, Thermocouple, RTD, Frequency Signals. Autostep, Sweep, and Memory Functions. More
Item# (PN): CA71 Shipping and Payment
The CA71 Calibrator is a small, lightweight, multifunction calibrator that can simultaneously source and measure voltage, current, resistance, TC, RTD, frequency, and pulse signals. The Calibrator incorporates rotary switches for simple handling. Just open the carrying case cover and connect the cables, and you're ready to take measurements.
A wide array of useful functions are offered. Including: Source (output can be set in steps: Power; Transmitter; Divided (n/M, eliminating need for calculations for percentage output); Autostep (changes can be sourced every 10% or 25%); online communication (RS-232); Sweep (linearly changes output over 16 or 32 seconds); Memory (50 sets); and Temperature Monitor function.

How is Temperature Measured?
Temperature can be measured via a diverse array of sensors. All of them infer temperature by sensing some change in a physical characteristic. Six types with which the engineer is likely to come into contact are: thermocouples, resistive temperature devices (RTDs Pt100 and thermistors), infrared radiators, bimetallic devices, liquid expansion devices, and change-of-state devices.
