BATTERY SYMBOL AND BATTERY REPLACEMENT
The battery symbol in the upper right corner of the display constantly provides the charge
status of the instrument batteries. The more the batteries discharge, the more the symbol gets “emp-
ty " …
... when the battery voltage reaches the minimum value for a correct operation, the symbol flashes.
At this point, only 5 minutes of autonomy are left and batteries should be replaced as soon as possi-
ble.
If the instrument is still used, the battery voltage will decrease still further and the in-
strument cannot ensure anymore a correct measurement; data recording is automatically in-
terrupted, as well as data logging and the instrument goes into STOP mode. Under a given
level, the instrument will automatically shut off. Data stored on memory will remain. The in-
strument cannot be switched on again until the battery level remains low.
The battery charge level is available on the menu main screen and on the program screen, ex-
pressed as a percentage value. Press MENU or PROG to view it. When the level is indicated by 0%,
5 minutes of autonomy are left.
The battery symbol changes into a plug when the instrument is connected to an external power sup-
ply.
Note : the battery symbol also flashes when the auto power-off is disabled (AutoPowerOFF = OFF).
To replace the battery, switch the instrument off, then unscrew anticlockwise the two screws
of the cover of the battery space. After replacing batteries (4 1.5V alkaline batteries - type AA),
close again the cover and fasten the two screws clockwise. Check date and time. If this operation
takes less than two minutes, no clock adjustment should be needed.
