Changing Batteries - Valeport miniSERIES Series Operating Manual

6.3. Changing Batteries

Changing batteries in the mini range of products is very simple process, which may be completed in under a
minute. Note that all data is saved in non-volatile Flash memory, so data is secure during the battery change
process.
The system clock does require battery power in order to maintain the current date and time settings, but the
instrument is fitted with a capacitor system to maintain a supply to the clock for a period of not less than 20
minutes after the removal of the battery. This should be more than sufficient to allow the battery to be changed.
In the event that clock settings are lost during battery change, or after an extended period of storage with no
battery fitted, then please use DataLog x2 software or the # codes defined in Section 3.9 to reset the clock.
· Disconnect any external connections, including the switch plug, from the instrument's SubConn connector.
· Loosen the Acetal lock ring at the top of the instrument housing – this should be achievable by hand.
· Pull the logger pack from the top of the instrument.
· Replace the single C cell in the instrument; note that the cell should be inserted with the positive end upwards.
Although it is possible to insert the battery incorrectly, it will not make contact.
· Check the o-ring on the logger pack for damage and debris. Clean it and smear lightly with silicon grease.
· Replace the logger pack, rotating slowly until the location pins align. Push the logger pack home.
· Replace the Acetal lock ring – hand tight is sufficient.
Note that for planned periods of extended storage, the battery should be removed from the instrument to
prevent accidental leakage.
