NOTE:
The data marked with ** has been recorded at an ambient temperature of 20°C±3, power
supply 230V±10%, with Pt100 ø6 inserted in the block.
The above-mentioned data keep valid for one year after the issuing of the calibrating
certificate; afterwards it is necessary to carry out the oven re-calibration.
Environmental range: tempe5 a +45°C, U.R. max. 80%
