3.4.11 Offset/gain setting mode (buffer memory addresses 22, 23: Un\G22, Un\G23)
(1) Specifies the channel to be adjusted f or the offset/gain settings.
(2) The channel for which the offset is to be adjusted is specified in buffer mem ory
address 22 (Un\G22) and the channel for which the gain is to be adjust ed is
specified in buffer memory address 23 (Un\G23) .
(3) Although it is possible to set multiple channels at the same time, set the offset and
gain separately (buffer memory addresses 22 an d 23: Set either Un\G22 or
Un\G23 to 0). If both are set at the same time, an off set/gain setting mode error
(error code 500) occurs.
(4) For Q64AD, b4 to b7 (information for CH5 t o CH8) are invalid.
(5) See Section 4.6 for the details of the of fset/gain settings.

3.4.12 Maximum and minimum values storage area (buffer memory addresses 30 to 45:Un\G30 to Un\G45)
(1) The maximum and minimum values of t he converted digital value for each
channel are stored.
(2) The stored values for all channels will be cleared to 0 when the operating
condition setting request (Y9) is set to ON an d the setting is changed or when the
maximum and mini mu m values reset requ est (YD) is set to ON.
(3) The maximum and minimum values are store d for each sample processing time
(measurement), even with channels for which averaging processing is specified.
