The OP-07 analog output option is for sending the weight data to an analog input unit.
The output is a 4 mA to 20 mA current output proportional to the display reading.
The output data is updated in synchronization with the display update.

Settings of F32 and F33
When entering the F32 or F33 settings (press the
ENTER key when “32” or “33” is blinking), the setting
value is displayed. Select the blinking digit by pressing
the key and increase the value by pressing the
1 key. By pressing the +/
 key, the polarity of the
value can be alternated. Press the ENTER key to
store the setting value into memory. After this the
display returns to selection of the Function number.
