5. Operation
•
Connect the relay to the “Digital Outputs”
socket of the 3B NETlog
TM
equipment using the
supplied mini DIN lead. It responds to digital
output A.
•
Preferably use 4-mm safety leads for the re-
maining electrical connections to the experi-
ment set-up.

•
Consult the instructions for the basic experi-
ment board U11380 for the electrical connec-
tions between the relay and the experiment.
•
Select one of the analog inputs (A or B) on the
3B NETlog
TM
module and follow the instructions
for the board regarding the experiment on ca-
pacitor discharge. All necessary output value
settings are specified here.
•
Conduct and analyse the experiment.
