3.3
Electrical data
Power supply
: via 4 alkaline manganese (LR6) Mignon (AA) 1.5V batteries
(maximum permissble nominal capacity 4000 mAh per cell)
running time (Duracell Plus) approx. 24 hours
(using FA sensor without display light)
or via 4 NiMH rechargeable Mignon (AA) 1.2V batteries
running time (Ansmann Digital 2850 mAh) approx. 26 hours
(using FA sensor without display light)
Open the battery compartment with a screw driver. Always change all 4 batteries at the same time,
checking for correct polarity. Only ever recharge batteries away from the unit using a suitable charger.
Always ensure that all 4 rechargeable batteries are fully charged before inserting. To close the compart-
ment press it firmly in the seal (in the direction of the connector sockets) and screw down tightly.
Mains supply
: via USB connection with PC or adapter plug
Supply current
: via USB connection not less than 300 mA
The mains supply is not electrically isolated from the outputs.
The "-" connection of the analog outputs and the earth of the USB connection have the same potential, i.e.
for EMC reasons a peripheral device should have potential-free inputs for evaluation of the analog outputs
when connecting to a PC.
