*1 When temperature drift correction is used, temperature drift correction time of 25 µs is added regardless of the number of channels used.
*2 This is a value when temperature drift correction is used. When temperature drift correction is not used, the conversion precision is as follows: Voltage: ±0.5 % of F.S., Current: ±0.6 % of F.S.
*3 This is a value when temperature drift correction is used. When temperature drift correction is not used, the conversion precision is as follows: Voltage: ±0.7 % of F.S., Current: ±0.7 % of F.S.
