Hui Gardens HF11 2 wire RTD simulator for PT1000 was made to be used as a calibration standard for the Hui Gardens HF3 WiFi RTD Meat Smoker Temperature Transmitter. Coarse (10kΩ) and fine (1kΩ) adjustment via 10 turn potentiometers allow precise setting of resistance value. Since there are no graduated steppings like a traditional decade box, it does not require calibration and is as accurate as the multimeter being used to characterize it.
The banana plug connectors are spaced such that the fancy two conductor leads can be used. Connect the two sets of banana plug connectors to use them together or disconnect to use separately.
