The .NET Framework 4 Client Profile is required. (*9)
*1: When “Auto” is selected, measurement range will be automatically changed according to the voltage being measured.
*2: MCR-4TC has superior noise filter, but the measurement may sometimes fluctuate due to strong noise. Especially when the recording interval is set to 200 ms or less, the filtering becomes weaker and hence the fluctuation may become greater.
*3: If the logging capacity is not filled at the end of one recording session, the logger can record up to 30 times.
*4: Group Recording may not be started depending on the recording or measurement interval specifications of the connected Master unit.
*5: Please check the T&D Website for information on memory cards whose operation has been confirmed.
*6: Battery life 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.
*7: For installation, it is necessary to have Administrator (Computer Administrator) rights.
*8: We recommend using an operating system in the same language as the display language. Operation in different languages is not guaranteed.
*9: During the installation process of the software, if not present, .NET Framework 4 Client Profile will be installed automatically.
The specifications listed above are subject to change without notice.
