Enter two equations as shown:
Note The first puts the current into channel A. The second equation runs after the first, and uses the new
current values in amps to calculate the power in watts.
Note *1000 is to convert the current in mA into A current in Amps to get power in Watts
Go to the Cleverscope Control Panel window.
On the Settings menu, click Analog Names and
Units.
In the Maths Graph Units area, change B Units to
W
and B Name to
Power
.
Click OK.
The graph shows the results of the Maths, first multiplying B x A B to get Watts in the B channel, and then
re-labelling the B axis to show power:
The peak power usage is 8W, (7.968 Mark 1:Chan B) while the normal power usage is 5W, (4.976 Mark
2:Chan B).
If we ignore the initial power pulse we could estimate the battery life at 6/5 = 1.2 Hours.
