13. IMPORTANT COMMENTS PERTAINING TO OPERATION
!
Please read this instruction carefully in order to ensure problem-free and optimized operation of the recorder.
In order to ensure the longest possible operating time of the battery without the need to change it, make sure to:
−
set the longest possible value of the measurement and recording interval (recommended > 10 min., 3:
MPer
,
Table 9.2)
−
use an SD/MMC card only when this is actually necessary; otherwise, use the internal memory
−
delete unnecessary files from the internal memory or the SD card before new recording starts
If one of the following conditions is met:
−
the measurement and recording interval is shorter than 10 min.;
−
an SD/MMC card is used
consider using an accessory power supply unit, which may extend the life of the battery to approx. 8 years.
Moreover, it is recommended to comply with the following advice:
−
do not disconnect the device from the computer in the course of communication via the USB interface,
which is indicated by the “
READ/WRITE”
and in the ARSOFT-CFG WZ1 software. USB communication is
present when mass memory is supported (internal memory or the SD/MMC card) and during operation of
the ARSOFT-CFG WZ1 software.
−
keep a copy of the current configuration file (
AR233.cfg
) in external memory (SD/MMC card, computer disk,
etc.) for the purpose of archiving and future off-line configuration.
If the recorder does not respond, the battery can be taken out for a short time and its charging level can be
checked (if the voltage is less than 3.3 V, the battery should be replaced with a new one).
14. CHANGING THE BATTERY
In order to change the battery, use a flat screwdriver and perform the following actions:
−
remove the back wall of the housing (as shown in Figure 14.1)
−
carefully take out the control board of the recorder from the housing (Figure 14.2)
−
replace the battery with a new one of appropriate type (chapter 4), observing the polarity in the holder
−
reassemble the device by putting the board and the back wall in their places
NOTE:
!
When the battery is replaced, the real time clock (RTC) is reset to zero and must be set again using
the ARSOFT-CFG WZ1 software; other elements remain unchanged.
