The DIS474 displays temperature as measured by a thermocouple input. All Wilkerson products are designed with RFI filters and lightning protection to reduce susceptibility to electrical noise and damage by lightning. The digital display utilizes an auto-zero dual-slope integrating A/D converter for accuracy and stability.

A unique analog thermocouple circuit with digital linearity compensation provides the optimum combination of resolution and thermocouple linearization. Linearization is better than ±1°C from –200°C (–328°F) to the thermocouple’s upper limit on all ranges. 0.1°C/0.1°F resolution is available for thermocouple types J, K, T, E and N (–199.9 to +199.9°C/°F). A temperature-sensing I.C. potted inside the input connector provides optimum cold-junction compensation.

All DIS instruments are gasketed and, when properly installed, are NEMA-4 splashproof. ZERO and SPAN controls are accessible by removing a gasketed front access panel.

A plug-in range card, accessible without opening the case, permits user recalibration for all thermocouple types and ranges. °C or °F is selected using switches accessible from the rear. A rear-panel jumper selects upscale or downscale burnout indication.

A complete set of engineering unit labels is sent with each DIS. Terminations are made to a screw terminal connector on the rear of the case.
