1.4 - Instruction for use of the optional Black Body insert

 Insert of the Black Body
Identify the following parts and proceed to the mounting as explained:

Cylindrical Thermal insulator – Mounted in the lower part of the pit of the
furnace.

Metallic Insert type Black Body cavity – Must be introduced in the pit joined with
a thermocouple type N mounted laterally.
Careful when entering the thermocouple in the cavity to not force the fragile
ceramic wall pit.

Ring-shaped cylindrical Insulator - mounted on top of the pit of the furnace
Note that the position of the slit of insulation should match the type N
thermocouple sheath laterally.

Connect the terminals of the thermocouple type N to the auxiliary input side of
the furnace T-1200PH and set the reading of the IN input to N type
thermocouple.
The combination constitutes an excellent mounted cavity blackbody with
emissivity above 0,95 and an effective target of Ø 20 mm well suited for calibration of
optical pyrometers.
Align the pyrometer to be calibrated with a black body cavity in the furnace in a
vertical position.
