Technical Specifications; Thermocouple Measurement Function; Constant Voltage (Tc6621,Tm6602 And Tm6630); G.1.2 Température Per Thermocouples (Tc6621,Tm6602 Et Tm6630) - AOIP TC6621 Mode D'emploi

G. TECHNICAL SPECIFICATIONS
The precision expressions mentioned herein apply from + 18°C to + 28°C, unless otherwise specified, and are expressed
in ± (n % L + C) where R = Reading and C = Constant expressed in practical units, for a confidence interval of 95%.
They apply to a device positioned in the reference conditions defined below:
Prior power-up of the device for temperature adjustment for 10 minutes
Following a significant thermal shock, it is advisable to allow the device to stabilize its temperature to use the
internal reference junction (CSF) with the utmost precision.
The precision includes the precision of the reference calibrations, the non-linearity, hysteresis, repetitiveness and long-
term stability over the time period mentioned.
