Field customize the Model 111 to lock-in 0.1° or 1° resolution, fixed °C or °F or front selectable °F/°C operation. Read and simulate 2-wire and automatically compensate for 3-wire RTDs with built in leads.

Resolution is 0.1°C or F simulating the full range of Platinum 100 ohm RTDs devices supplying a continuous excitation current of 0.09 to 1.1 mA. From 1.1 to 5.800 mA continuous excitation current the 111 resolution automatically adjusts to 1°C or F. Ohms range provides 0.01 ohm resolution from 0.00 to 410.00 ohms which automatically switches to 0.2 ohm resolution for continuous excitation currents above 1.1 mA.

"Quik-Chek" function stores three output temperatures to real convenience. The model 111 simulates key temperatures for repetitive calibrations. Turn the knob to check trip points, controller action or hysteresis. The fast response 111 sets quickly without overshoot. Memory is retained even when power is off.

The Model 111 display gives you fast, accurate temperature measurement with 0.1 ohm resolution. Two and three wire hookups assure accuracy in short or long cable runs. Open RTDs and leads are detected and indicated on the LCD display. Two readings per second track fast moving temperatures.

"MAX" and "MIN" memories are continuously updated from turn-on or whenever the "RESET" button is pressed. Model 111 gives you a handy tool to monitor temperature for drift or control deviation. Just flip the Quik-Chek switch to display the minimum and maximum temperature measured since reset.
