9.5.8 Battery charger
The battery charger supplied with the meter can work at either 50 Hz or 60
Hz with a supply voltage range between 100 and 240 Volt.
It is supplied with different connectors to the supply mains in accordance
with the various national standards.
9.5.9 To substitute the
mains connector
To substitute the mains connector, simply remove the one installed on the
battery charger and replace it with the one that is in compliance with its
use.
9.5.10 To check the
internal batteries
If the internal batteries are to have the greatest autonomy, we recommend
that a full recharging cycle be carried out before using the meter.
To do this, go through the following procedure:
• Connect the battery charger to the power socket
• Link the output connector of the battery charger to the input
CHARGER on the side panel of the meter
• 8053 DISPLAY will switch on automatically, after making a sound
produced by the internal buzzer, the display will be activated and the
meter will start its auto-check and begin the procedure for recognising
the probes.
• The main window will therefore be activated and the status of the
charge (CHG) of the battery will be displayed in the STATUS box
Indications of the battery in the STATUS box:
The status of the charge of the battery is displayed in the top left-hand
corner of the STATUS box. The symbol of a small battery will be filled up
proportion to the status of the battery charge.
The battery charger will be automatically stopped when one of the
following occurs and a small connector will be displayed relating to a letter
indicating the end of the recharging cycle.
Display of the following letters means:
V – The voltage of the batteries has reached 1.45 V/element (7.25 total),
and therefore the recharging cycle is complete.
H – The recharging cycles has lasted for more than 4 hours.
T – The temperature of the batteries, compared to the temperature stored
after ten minutes recharging, has increased more than 10 °C, or the
temperature of the battery has reached 65 °C.
When the recharging cycle is finished, the 8053 DISPLAY is ready for use.
To avoid damage to the batteries, when the T symbol appears, the
recharging cycle is stopped automatically.
To finish the recharging cycle wait for about ten minutes for the
batteries to cool down then reconnect the battery charger.
Battery charger: DC, 10 - 15 V, ~ 500 mA
Connector:

ALWAYS connect the battery charger to the mains power BEFORE
connecting the DC output to 8053 DISPLAY. The battery charger has
an internal protective circuit that will not let it work if there is a load
connected to the battery charger before the connection to the mains
is activated.
In order to safeguard the features of the batteries, it is crucial to have
a complete recharge before storing them for periods longer than 4
months. Therefore, it is warmly suggested recharging the batteries at
least every 4 months even though the device has not been used.
