DR4300 Circular Chart Recorder

4.5.1.3 Viewing the operating parameters

Contents of display

The upper display uses four characters to display the value of the input. During normal operation, you can view various real time values and setpoints in the lower six-character display if the recorder supports

control. Each value will be labeled. Press the DISP

key to scroll through the displayed values listed in

Table 4-27.If the recorder does not support control, then only the label “INP” or the totalizer value will appear in the lower display. (The input value will be in the upper display.)

The display shows only those parameters and values that apply to your specific model and the way in which it was configured. For recorders with two pens, remember that any controller-related values displayed correspond with the lighted INP indicator. “1” means that the values apply to the pen 1 input

channel and “2” means that the values apply to the pen 2 input channel. Press FUNC between input 1 and input 2.
