CA71 Multifunction Calibrator
Brand: Yokogawa Electric CorporationThe CA71 HANDY CAL calibrators are comprehensive generating/measuring instruments for all your calibration and equipment checking needs at maintenance sites.
The CA71 can simultaneously generate and measure voltage, current, TC, RTD and pulse signals, thus you don’t need to prepare many instruments.
In addition, the incorporated rotary switches of good repute enable operations so smooth that an incorrect measurement caused from erroneous operations can be prevented.
Features- Source and measure operations can be performed at the same time. (Select from the following source signal and measurement signal options: voltage, current, resistance, thermocouple (TC), resistance temperature detector (RTD), frequency, pulse).
- AC Voltages, Including Supply Voltage, can be measured
- Includes a Wide Array of Additional Functions
- Easy Operation
- Compact Size and Lightweight
