*1: When "Auto" is selected, measurement range will be automatically changed according to the voltage being measured.
*2: If the logging capacity is not filled at the end of one recording session, the logger can record up to 30 times.
*3: Group Recording may not be started depending on the recording or measurement intervalspecifications of the connected Master unit.
*4: Please check the T&D Website for information on memory cards whose operation has been confirmed.
*5: Battery life varies depending upon multiple factors including measurement interval and 50-60 Hz filter setting. All estimates are based on operations carried out
with a new battery and are in no way aguarantee of actual battery life.
