Kvaser Memorator 2xHS v2 User’s Guide
11 (26)
The battery inside the Kvaser Memorator 2xHS v2 is used for powering the real
time clock and ensuring a safe shutdown of the device when disconnected. When
in logger mode, the Kvaser Memorator 2xHS v2 can also use the battery to extend
the logging time by a number of seconds (accessible from the Power Settings in
Kvaser Memorator Config Tool).
To maintain a healthy battery you need to:
•
Always connect the Kvaser Memorator 2xHS v2 to a properly powered USB
hub when connected to a computer.
•
When using the feature to extend time to live after CAN power is
disconnected, always make sure to recharge the device between each use.
To fully recharge the device, connect to power for up to 20x “live time” (e.g.
15s battery use might require up to 5 min of recharging).
•
If the Kvaser Memorator 2xHS v2 is not used regularly, ensure the device is
recharged at least twice a year overnight at room temperature.
All charging times are given at temperatures between −10
◦
C to
+40
◦
C. In warmer and colder temperatures the charging time will
increase.
See Section 4.3, CAN connectors, on Page 17 for information on how to connect
power to the connector. The supply power should be in the range specified in
Section 4.2, Technical data, on Page 17.

SD Card
You can use SD, and SDHC cards with your Kvaser Memorator 2xHS v2 for
logging. The Kvaser Memorator 2xHS v2 is built with industrial environments in
mind, but please note that the SD card used can be a limiting factor. By using a
quality card that matches the specifications of the Kvaser unit, you minimize the
risk for data corruption or lost data.
Insert the SD card upside down into your Kvaser Memorator 2xHS v2 (see Figure 4
on Page 12). Do not apply excessive force.
To remove the SD card, open the access door and using a finger or a small coin,
gently press on the edge of the SD card until a click is heard. Release the card and
it will partially eject. Remove the SD card completely.
The setting of the write protection switch on SD cards is
disregarded by design. The Kvaser Memorator 2xHS v2 will write
to the disk even if the write protection switch is set.
