*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
interval specifications of the connected Master unit.
*4: Battery life in the table above is for two AA Alkaline type batteries, and varies
depending upon multiple factors including ambient temperature, recording
interval, number of measurement channels, and frequency of data export to a
memory card. All estimates are based on operations carried out with a new battery
and are in no way a guarantee of actual battery life.
*5: Software on CD-ROM is not supplied with the product. Free software download
and information on OS compatibility is available on the Software page of our
website at tandd.com/software/.
