Figure C-1: Resolution Chart for the ET-016 Probe
ET-016: Extended exposure to temperatures above 70°C may result in permanent
resistance drift, resulting in loss of ±0.2°C tolerance over the 0 to 70°C temperature
range. Extended exposure to temperatures below 0°C may result in some mechanical
damage due to thermal contraction effects.
