DR4300 Circular Chart Recorder
4.5.2.5 Selecting Factory or Field Calibration Values
Introduction
Recorders are calibrated at the factory. The calibration values for each pen channel are stored on the printed
circuit assembly associated with the pen. In addition, provision is made for the storage of field calibration
values. The procedure for calibrating an input is provided in Section 5 – Input and Output Calibration for
Recorder with Display. Entering field calibration values does not affect the stored factory calibration.
The "LD CAL" parameter in the input set up group for each pen channel permits you to specify whether
factory or field calibration values are to be used by the recorder.
Procedure
Follow the procedure in Table 4-32 to select factory or field calibration values.
ATTENTION
If you change the type of input used by the recorder, you must change the setting of the "IN TYP"
parameter in the input set up group (see Subsection 4.3.7). Changing the input type also requires
changing the settings of hardware switches at SW6 (see Subsection 4.3.5.2).

ATTENTION
FLD uses the same calibration values as FAC. When field calibration is
performed, the value of LD CAL is automatically set to FLD at the completion
of the field calibration operation.
Be sure the correct sensor is connected to the input terminals and resume
normal operation.
