MEMORY
Type I COMPACT FLASH up to 8 GB (512 Mbytes supplied).
Storage of values sampled by the AD converter (all input channels) or processed data (e.g. EN50160 reports).
With the supplied 512 Mbytes it is possible to store up to 9350 records, corresponding to 3 hours of uninterrupted campaign with a mains frequency of 50 Hz.
Each record includes the sample values of 60 periods on 7 channels.
Ex.: with a 8 GB memory, if 1 record every 5 minutes is selected, 240 days of storage are achieved; if 1 hour is selected, 8.5 years are achieved.

BATTERY CHARGER Internal to the instrument
MAXIMUM BATTERY
RECHARGE DURATION
about 20 hours, with instrument on
about 10 hours, with instrument off
NOTE 1
The charge duration and lifetime of the batteries are influenced by the number and depth of the charge/discharge cycles carried out and by environmental factors such as, for example, temperature.
NOTE 2
To increase the battery operating time of Energy Explorer, the screen backlight is switched off if no key is pressed for 3 minutes (press any key to switch it on again).
NOTE 3
The instrument turns off automatically if the batteries reach a voltage level below 5.9V, to prevent excessive battery discharge.
NOTE 4
If the instrument is not used for long periods (> 1 month), remove the batteries to preserve their charge/discharge capacity.
