Optional part
*1. Energy data (Wh,varh,VAh) is measuring data in ME96SS. These are not difference value calculated by logging cycle.
*2. It is the period until capacity of 2GB SD memory card is filled in always-on connection. Data amount depends on the number
of characters. It is the logging period when data is output in maximum volume.
*3. Make sure to use the SD memory card manufactured by Mitsubishi Electric Corporation (Model EMU4-SD2GB). Using the
other types of the SD memory card may cause the trouble such as data destruction of the memory card or system failure.
*4. For purchase of optional parts, contact the shop you bought this product.

Lithium battery (Embedded in ME-0000BU-SS96)
Total time of compensation is 5 year (average daily temperature is less than +35°C).
(Lifetime expectancy of lithium battery is 10 year) (average daily temperature is less
than +35°C).
It is impossible for customer to exchange the battery. Please consider renewal.
Memorized in FRAM (nonvolatile memory)
The data is memorized during power failure.
Memorized in SRAM (volatile memory)
Data is erased if power failure occurs under low battery voltage condition (BAT.LED
turns on).
Clock time operation is stopped if power failure occurs under low battery voltage
condition (BAT.LED turns on). After power recovery, timing is started from Jan 1, 2016
00:00:00.
