one parameter can be sent to a printer or computer as a block.
Selecting ??? displays a sublist for choosing the meter parameters to appear
in the print block. All active parameters entered as ??? in the sublist will be
transmitted during a block print. Parameters entered as ?? will not be sent.

The “Print All” ( ?????? ) option selects all meter values for transmitting
( ??? ), without having to individually select each parameter in the sublist.
Note: Inactive parameters will not be sent regardless of the print option
setting. For example, the Cycle Counter and Cycle Counter Start values will
only be sent when the Cycle Counter is enabled. If disabled, these parameters

parity bit for outgoing data. If parity is set to ?? , an additional stop bit is used
to force the frame size to 10 bits.
