OPERATION OF IAQRAE
2-6
2.4 Data Protection
When the monitor is turned off, all the current real time data
including peak, minimum, and elapsed time are erased.
However, the datalogged data are preserved in non-volatile
memory. Even if the battery is disconnected, the datalogged
data will not be lost. When the monitor is off, the real time clock
will continue to operate until the battery is completely drained
(usually in 5-7 days without any charging).
If the battery is completely drained or is disconnected from the
monitor, the real time clock will continue to operate for another
30 days. When the real time clock is lost, the information needs
to be re-entered. (See Section 4.5.5 Change Real Time Clock)
Datalog monitor versus Non-Datalog monitor
There are two versions of the PGM-5210 Multi-Gas Monitors:
Datalog monitors and Non-Datalog monitors. A Datalog monitor
allows the user to store the gas concentration readings. (See
Section 2.10 Datalogging)
During the power on sequence, a letter “D” following the
version number indicates that the monitor is configured as a
Datalog monitor. The absence of a letter “D” indicates a Non-
Datalog monitor.
The user may upgrade a Non-Datalog monitor to a Datalog
monitor. Call the factory for information on how to order the
upgrade kit.
