13.3 Measurement Specifications
170
Note 1: All CH4 displays turn ON when CH4 is set to AC+DC or DC.
Note 2: When CH4 is turned OFF, all CH4 display values and waveforms are also turned OFF.
Note 3: Meaning of "*" in the "MAX/MIN/AVG" column
Indicates that maximum, minimum, and average values (all) can be displayed during the MAX/MIN/AVG TIMEPLOT interval.
Note 4: Meaning of "**" in the "MAX/MIN/AVG" column
Indicates that maximum and minimum values (all) can be displayed, regardless of the MAX/MIN/AVG TIMEPLOT interval.
*1: CH3 is calculated but not displayed. It can be output only as binary data.
*2: Select either.
