Reset of totalization* 1
*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
range-shift
Printing area can be divided up to 5 ranges. It
switches the range according to the measured
values automatically for printing.
Compressed/
Expanded Specific printing range is compressed or
expanded for printing.
Zone scale Printing area is divided into 2 to 4 zones*. Data
of each channel is printed in the relevant zone.
*RD200 … 2, RD2800 … 2 to 4
