4) With an external device, etc. connected to the terminal of the channel to be adjusted, observe output voltage or current value.
First, in the condition that bit 15 of the parameter setting data register (offset address +6) is set OFF, adjust output value by
setting ON and OFF bit 8 (output value Down) and bit 9 (output value Up).
5) After the completion of offset adjustment, set ON bit 0 (zero) of the parameter setting data register (offset address +6) to
write the offset adjustment value in the module internal EEPROM. When bit 0 (zero) of offset address +2 is set ON, the
writing of EEPROM is completed. After confirming this, set OFF bit 0 (zero) of the parameter setting data register.
6) Then set bit 15 ON of the parameter setting data register (offset address +6) and, in the same way as offset adjustment,
adjust output value by setting ON and OFF bit 8 (output value Down) and bit 9 (output value Up). (Gain adjustment)
