7.9.4 Linefeed
The final parameter in the serial interface menu is the linefeed mode. This pa-
rameter enables (on) or disables (off) transmission of a linefeed character (LF,
ASCII 10) after transmission of any carriage-return.

7.10 Calibration Parameters
The operator of the instrument controller has access to a number of the calibra-
tion constants namely R0, ALPHA, DELTA, and BETA (cold side only). These
values are set at the factory and must not be altered. The correct values are im-
portant to the accuracy and proper and safe operation of the instrument. Access
to these parameters is available to the user so that in the event that the control-
ler memory fails the user may restore these values to the factory settings. These
constants and their settings are on the Report of Calibration that is shipped with
the instrument.
CAUTION: DO NOT change the values of the instrument's calibration
constants from the factory set values. The correct setting of these parame-
ters is important to the safety and proper operation of the instrument.
The calibration parameters menu is indicated by,
CAL
Calibration parameters menu
Press “SET” five times to enter the menu. The calibration parameters menu
contains the parameters, R0, ALPHA, DELTA, and BETA (cold side only)
which characterize the resistance-temperature relationship of the platinum con-
trol sensor. These parameters may be adjusted to improve the accuracy of the
calibrator.
The calibration parameter name flashes on the display and then the current
value is displayed. The value of the parameter may be changed using the “UP”
and “DOWN” buttons. After the desired value is reached press “SET” to set the
