Section 7—Calibration

Calibration offset offsets the displayed value. Usually, this option is

used to match displays of two different instruments that are mea-

suring the same temperature, but are displaying different tempera-

tures due to different thermocouple accuracy or placement of the

thermocouples. Caution is advised when adding an offset to the

display, since the actual sensed temperature will not be displayed.

Calibration offset (coFF) is available in the conﬁguration mode, but

only displays if the security lock (LocH) is set to 736.

Factory Default

Recovery

This option allow you to return the controller’s conﬁguration param-

eters back to the factory default values (except for the LocH menu).

This parameter could be used when moving a unit from one applica-

tion to another to give the operator an easy place to begin setup of

the unit.

Factory Default Recovery is performed in the Conﬁguration Mode,

menu dFLt. The security lock (LocH) must be set to 736 to perform

a factory default recovery.

To reestablish the factory default values:

1. Disconnect load power.

2. In the Conﬁguration Mode, set security level (LocH) to 736.

3. Go to menu dFLt and press . The controller will automatically

reset the values. When the display cycles from rEdy to donE, the

recovery is complete.

Calibration Offset

The Chromalox 2110 Temperature Controller is factory calibrated

before shipment. Recalibration is not needed when you receive

and install the product. Periodic calibration checks or adjustments

should not be necessary under normal operating conditions. Chro-

malox recommends you recalibrate the controller if all instruments in

your facility are periodically calibrated to a known standard.

The 2110 always retains the original factory calibration values for

the J, K, and RTD inputs. In an application, only one of these sensor

inputs will be used. The 2110 only can retain manual calibration for a

single sensor.
