Electrical Requirements
The BF35 Viscometer is to be powered by a DC power source capable of
providing between 13 and 16 volts DC. The equipment is current limited to 4
amps by a user-replaceable fuse. However, we suggest that the power supply
be current limited to less than 4 amps to provide additional protection to the
equipment.
