*This operation is only available for the “totalization” (option).
3) Printing format
Trace printing format, c Automatic range shift, d Compressed/Expanded or e Zone scale, is selectable for each channel.. The format e is common to all channels.
Automatic | Printing area can be divided up to 5 ranges. It | |
switches the range according to the measured | ||
values automatically for printing. | ||
| ||
Compressed/ | Specific printing range is compressed or | |
Expanded | expanded for printing. | |
| Printing area is divided into 2 to 4 zones*. Data | |
Zone scale | of each channel is printed in the relevant zone. | |
| *RD200 … 2, RD2800 … 2 to 4 |
