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. The linefeed parameter is
indicated by,
LF= On
The mode may be changed using "UP" or "DOWN" and pressing "SET".
LF= OFF

Calibration Parameters

The operator of the 7380 controller has access to the Hard Cutout and a number
of the bath calibration constants namely R
These values are set at the factory and should not be altered. The correct values
are important to the accuracy and proper and safe operation of the bath. Access
to these parameters is available to the user only so that in the event that the con-
troller memory fails the user may restore these values to the factory settings.
The user should have a list of these constants and their settings with the
manual.
CAUTION: DO NOT change the values of the bath calibration constants
from the factory set values. The correct setting of these parameters is im-
portant to the safety and proper operation of the bath.
The calibration parameters menu is indicated by:
Press "SET" five times to enter the menu.
The calibration parameters R
resistance-temperature relationship of the platinum control sensor. These pa-
rameters may be adjusted by an experienced user to improve the accuracy of
the bath.

Hard Cutout

This parameter is the temperature above which the unit shuts down automati-
cally. The parameter is set at the factory to approximately 120°C and can be
changed only through the variable resistor. This parameter cannot be changed
