The H261Temperature Indicator Tester accurately tests calibration and operation of servo-powered and D’Arsonval temperature indicators. The H261 Temperature Indicator Tester: • Simulates thermocouple, resistance temperature devices (RTD’s) and other millivolt transducer signals • Troubleshoots thermocouples and millivolt sources by measuring their outputs • Measures thermocouple circuit resistance • Includes synchro input/output circuits to provide testing and troubleshooting of synchro temperature indicator transmitters and receivers (model H261-11) • Tests three types of RTD’s • 90.38 ohm nickel probe (range: –70 to 300 °C) • 50.00 ohm nickel probe (range: –50 to 300 °C) • 50.00 ohm platinum probe (range: –70 to 100 °C) Servo type indicators, requiring AC or DC power, are powered by adapters that have external power connections.
