Power supply
Instrument is dedicated for the operation from the internal replaceable battery.
Power consumption from the 6V source is approx. 190 mA (at + 20C)
So, typical operating time from 4 x AA alkaline batteries will be about 9.5 hours.
SVAN 979 can be also powered from the AA Type rechargeable batteries.
Note: For temperatures below 0  C operating time can decree (depending on the batteries)!
Note: Using of the USB Flash Disk (memory Stick) will increase power consumption. Maximum power
consumption on the USB Host Port might be up top 150 mA. In such a case battery operating time
will be reduced to approx. 6 hours!
Instrument can be also powered from the external source (e.g. SA 17A or car battery) with the DC Voltage
from 6 V to 24 V.
Voltage ripple should not exceed

5%.
External Power requirement is voltage dependent:
for 6 V - 190 mA DC,
for 24 V - 45 mA DC.
