The presence of symbol " " on the display indicates that the internal
batteries are low and that it is necessary to replace them (if alkaline) or
recharge them (if rechargeable). For this operation, proceed as follows:
Battery replacement
1. Switch off remote unit SOLAR03
2. Remove any probe from its inputs
3. Open the battery compartment cover on the back (see Fig.3 – part 2)
4. Remove the low batteries and replace them with the same number of
batteries of the same type (see § 7.2), respecting the indicated
polarity.
5. Restore the battery compartment cover to its position.
6. Do not scatter old batteries into the environment. Use the relevant
containers for disposal.
The instrument is capable of keeping data stored even without
batteries.
Recharging the internal battery
1. Keep the remote unit SOLAR03 switched on
2. Remove any probe from its inputs
3. Connect the USB-C/USB-A cable to the instrument's input (see Fig.1
– part 2) and to a USB port of a PC, or use a 230V/5V, 50/60Hz,
>500mA mains power supply, not provided with the instrument. The
symbol " " is shown on the display, to indicate that recharging is in
progress.
4. As an alternative, it is possible to use the optional external battery
charger (see attached packing list) to recharge the rechargeable
batteries.
1. Periodically check battery charge status by associating the remote
unit to the Master instrument and opening the information section
2. CLEANING
Use a soft and dry cloth to clean the instrument. Never use wet cloths,
solvents, water, etc.
