1. Insert the inconel block into well of furn ce.
2. Connect the ‘CALsys 1200’ to suit ble power supply & Switch ON the Dry b th source nd set
the desire temper ture v lue in PID by using UP & Down key.
3. Insert the reference (M ster) temper ture sensor nd UUC (Unit under c libr tion) into the
thermowell (inconel block).
4. PV (Present v lue) displ y in controller will gr du lly rise until it re ches the set point
temper ture. The controller t kes some times to re ch the set-point depending on the sp n.
Furn ce is st ble when PV is equ l to SV (Set V lue).
5. M ster sensor t ke some times to re ch the setpoint temper ture nd st ble t temper ture
ne r bout controller set temper ture.
6. When temper ture of the m ster nd UUC (Unit under c libr tion) re st ble record the
re dings of m ster sensor.
7. Comp re the UUC re ding with the m ster’s re ding & find out the error by comp rison method.
8. Reset the controller nd / or repe t the c libr tion for nother c libr tion point or for nother
sensor.
9. When the c libr tion is complete, reset the controller to 0°C & w it until the unit h s cooled to
below 100°C, before moving the ‘CALsys 1200 to new loc tion the ‘CALsys 1200’ must be cooled
below 100°C before it c n be put b ck into its c rrying c se.
