MCM-204
Data Keep : By default, the MCM-204 stores history data only in
RAM and the data is lost when the system reboots. Select Enable
to also save history data to internal storage. The amount of disk
space allocated for this purpose is 300MB. When that limit is
reached, data that has gone for the longest period of time without
being accessed will be overwritten first, thus preserving the data
that has been accessed most recently.
Device Calibration : The MCM-204 can be recalibrated if neces-
sary. Though the MCM-204 is factory-calibrated before shipment
and associated calibration constants are written to the on-board
EEPROM, it is possible that, over time or depending on tempera-
ture conditions, recalibration may become necessary.
