*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

range-shift

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
