Memory Map
Selecting [YES] for this item enables a snapshot display of current memory usage. In this
display, the asterisk indicates a used memory block, a space indicates a free block, while a
dash character indicates unused filler.
Defragment
Selecting [YES] for this item consolidates memory data blocks into contiguous storage;
collapsing the filler regions. You may be able to use an additional block for site or Datalogger
storage as a result. Use this command if you seem to be out of memory even though the
[Log Memory Left] item indicates free capacity.
7.7 Analog Out Setup
The flow meter provides current, voltage and pulse-rate analog outputs. The [Analog Out
Setup] menu allows you to assign data functions for these signals. The transmitter terminal
strip contains the analog output terminals.
Table 7- 6 Analog Outputs
Io (Isolated Current) 4 to 20mA varies in proportion to an assigned
data function.
Vo (DC Voltage) 0 to 10 VDC varies in proportion to an assigned
data function.
Pgen (TTL Logic) 0 to 5000 Hz varies in proportion to an assigned
data function.
