16. 16. 16. 16. 4 4 4 4- - - -20mA Analog Output (OP 20mA Analog Output (OP 20mA Analog Output (OP 20mA Analog Output (OP- - - -07) 07) 07) 07)
The OP-07 analog output option is for sending the weight data to an analog input unit.
The output is a 4mA to 20mA 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.
Set the value using the 0 - 9 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.
