The calibration parameters are accessed by pressing “SET” after the name of

the parameter is displayed. The value of the parameter may be changed using

“UP” or “DOWN”. After the desired value is reached, press “SET” to set the

parameter to the new value. Pressing “EXIT” causes the parameterto be

skipped ignoring any changes that may havebeen made.

6.14.1 Hard Cutout (hot side only)

This parameter is the temperature abovewhich the unit shuts down automati-

cally and is only adjustable through the hot side. The valueof thisparameter is

set at the factory and cannot be changed by the user.

The hard cutout parameter is indicated by,

CutOut Flashes for one second and then the hard cutout setting is

displayed

670 Current hard cutout setting

Press “EXIT” to continue to the next parameter.

6.14.2 R0

This probe parameter refers to the resistance of the control probe at 0°C. The

value of this parameter is set at the factory for best instrument accuracy.The

value ranges from 95 to 105. The R0 parameter is indicatedby,

r0 Flashes for one second and then the R0 setting is displayed

100.014 Current R0 setting (100.014)

Tochange the R0 setting, press “UP” or “DOWN”.

99.999 New R0 setting

Toaccept the new setting, press “SET”. Press “EXIT” to continue without stor-

ing the new value.

SAccept the new R0 setting

6.14.3 ALPHA

This probe parameter refers to the average sensitivityof the probe between 0

and 100°C. The value of this parameter is set at the factory for best instrument

accuracy.(The ALPHA value is the displayed value times 10–7.)
