The TT1000A is a completely self-contained, battery powered, aircraft turbine temperature system tester capable of measuring system lead resistance, insulation, and performing indicator run-outs with a range up to 1000 C°. The unit was specifically designed to meet all requirements for testing aircraft Chromel/Alumel (CH/AL) turbine temperature measuring systems and provides an accurate display of thermocouple outputs in degrees Celsius (°C). 

• Measures resistance of thermocouple, rings and system lead circuits
• For use with bench testing indicators
• Automatic temperature compensation test leads
• Thermo couple and lead resistance measurements to 0.01
• Insulation measurements up to to (2) megohms 
• Large, 9 mm (0.35 in) high character, 3-1/2 digit liquid crystal display
• Measures/displays CH/AL thermocouple values in degrees Celsius (ºC)
• Simulates CH/AL thermocouple w/wo simulated system lead resistance
• Pre-programmed legends
