Battery replacement
HD2013-DB uses an internal 3.6 V lithium-thionyl chloride (Li-SOCl
2
)
not rechargeable
battery, size C, with Molex 5264 2-pole connector. The charge status of the battery is
constantly monitored and displayed.
When the battery voltage drops below a certain value, the instrument automatically turns off
the backlit of the display, so as to minimize the battery consumption and allow the instrument
to continue to perform the measurement functions. When the backlit is turned off, it is
recommended to replace the battery soon.
If the battery voltage drops further to a level that does not allow the correct operation of the
instrument, the message "CHANGE BATTERY NOW!" is displayed; in such a case, the battery
replacement is necessary.
The instrument is equipped with non-volatile memory
: the data remain stored even if
the battery is discharged and disconnected.
To replace the battery, proceed as follows:
1.
disconnect the instrument from the PC, if connected;
2.
unscrew the four screws fixing the front cover;
3.
remove the battery connector and take the battery out of its holder;
4.
insert the new battery paying attention to the correct polarity (the connector is provided
with a protection device that prevents the reversal of polarity);
as an alternative to the lithium battery, if not available, three 1.5 V alkaline batteries can
be used, to be inserted in the batteries holder shown in the figure. In such a case,
connect the batteries holder connector to the battery connector on the board of the
instrument;
5.
close the cover with the fixing screws; when closing, verify that the sealing gasket is
properly positioned; the screws must be securely fastened.
