Conditions:
[1] Accuracy figures represent the uncertainty added by the measure-
ment circuitry inside the instrument. Sensor uncertainty is not in-
cluded, which can add up to 2
◦
C.
[2] Measured by a monitor thermistor on the TEC stage. The LDC500 is
operated in an environmental chamber between 0
