Can I use any 1/2AA battery like a Saft or EVE battery?
Why do the LEDs flash after connecting my logger to a PC?
If the LEDs flash sequentially it may indicate that there is a problem with the battery. This could
either be a flat battery, which should be replaced, or a battery where a passivation layer has formed.
Leaving the data logger connected to a PC for about 30 seconds will remove this layer. After this,
remove and re-install the batteries to reset the data logger.
If you see the sequential LEDs after disconnecting the logger from a PC then the logging session will
not start. You should check the battery condition and then repeat the setup procedure using the PC
software.
How often should I calibrate my logger?
We recommended yearly calibration however your procedures may require you to calibrate more
(or less) frequently.
How long will the battery last?
Under typical use, the battery will last approximately 1 year at a 15 minute recording interval. If you
download more frequently, or use the logger at low temperatures, the battery life will be reduced.
What do the different things (‘---‘, ‘PS’ or ‘dS’) on the LCD screen mean?
If you see '---' on the display of your data logger when you press the button, this indicates that the
logger is not logging.
'PS' indicates that the data logger is in Push-to-Start mode. Pressing the button will start the data
logging session.
'dS' indicates that the data logger is in Delayed Start mode. The data logging session will start at the
time specified when the logger was set up.
No, it is critically important to use a ER14250BH. Batteries other than this may temporarily or permanently
damage your logger. The ER14250BH is the only battery which can supply sufficient pulsed current
to the logger.
