1. For ambient temperature of 23°C.
2. Time from when the SETPOINT is reached to when the unit is within stability specification.
3. The temperature range may be limited by the reference probe connected to the readout. The built-in reference accuracy does not include the sensor probe accuracy. It does not include the probe uncertainty or probe characterization errors.
4. Measurement accuracy specifications apply within the operating range and assume 4 wires for PRTs. With 3-wire RTDs add 0.05 Ω to the measurement accuracy plus the maximum possible difference between the resistances of the lead wires.
5. The thermocouple input readout is sensitive to EM fields in the frequency range of 500 MHz to 700 MHz.
