20 TECHNICAL FEATURES
Power supply Rechargeable 3.7 V Li-ion internal battery, 2250 mA/h capacity,
3-pole JST connector.
Optional external power supply unit ( SWD05 ), to be connected to
the mini-USB connector of the instrument.
If connected to PC, it is powered from the computer’s USB port (500
mA at least).
Battery life 18 hours of continuous operation (typical duration starting from a fully
charged battery and with 3 connected Pt100 probes). The actual bat-
tery life depends on the number and type of connected probes .
Logging Manual or automatic with 1, 5, 10, 15, 30 seconds / 1, 2, 5, 10, 15,
20, 30 minutes / 1 hour configurable interval
Storage capacity SD memory card, capacity up to 4 GB.
The logging duration depends on the number of stored quantities and on
the capacity of the SD memory card employed. E.g., with a 4 GB SD
memory card, the logging duration is of some months even if several
quantities with minimum logging interval of 1 s are recorded.
Inputs 3 inputs with 8-pole DIN45326 connector. According to the type of
connected probes, the instrument can manage up to 36 quantities.
