Description
Overview
The Ectron 1140A is a precision thermocouple simulator and measurement instrument designed for calibration and testing. It provides four primary functions: thermocouple signal simulation, thermocouple signal measurement, precision dc voltage generation from microvolts to ±11 volts, and dc voltage measurement over the same range. The instrument features output impedance of less than 0.05 Ω on all ranges, minimizing loading errors and maintaining high accuracy.
Key Features
- 0.06°C accuracy for common thermocouple types with cold junction compensation
- Simultaneous thermocouple simulation and measurement capabilities
- DC voltage sourcing and measurement from nanovolts to ±11V with 0.0025% + 2.0 µV accuracy
