MEMO:
For items other than DPOT-K, displaying value at the time of the latest potential control.
2TR-PPR Use it to check the output value of the paper separation voltage of the secondary transfer DC voltage generated last.
2TR-BASE Use it to check the output value of the reference voltage of the secondary transfer DC voltage generated last.
1TR-DC-Y Use it to check the output value of the primary transfer DC voltage (Y) generated last.
1TR-DC-M Use it to check the output value of the primary transfer DC voltage (M) generated last.
1TR-DC-C Use it to check the output value of the primary transfer DC voltage (C) generated last.
1TR-DC-K Use it to check the output value of the primary transfer DC voltage (K) generated last.
CHG-AC-Y output value of primary charge AC voltage (Y) output last
CHG-AC-M output value of primary charge AC voltage (M) output last)
CHG-AC-C output value of primary charge AC voltage (C) output last)
