Page 16 TUNE-MIN The (0)4mA or 0V value can be tuned precisely with this setting. The initial minimum analog output value is (0)4mA or 0V. However, this value might differ slightly due to ambient influences such as temperature for example. Before tuning the signal, make sure that the analog signal is idle (not used) for any application! After pressing PROG, the current will be about 4mA (0mA or 0V). -
