Figure 18. Measuring a Power Source, Method 2
Configure the channel as follows -
•
Method 2 may provide improved results for applications with very
low voltage and very high current, when using the internal shunt.
•
At high frequencies, the wiring length between the source and the
current and voltage measurement points should be kept as short as
possible to avoid inductive and capacitive losses causing inaccuracies.
•
Optionally, set
Wiring Impedance
to (W1 + W2) ohms. The
instrument will always automatically adjust for the internal shunt
burden resistance if the channel is set to use the internal shunt. Other
than the internal shunt burden, include all wiring resistances between
the source and the points at which the voltage is measured in the
entered value for wiring impedance.

Set
V Burden Compensation
to
NO
.
•
If the current measurement terminals are reversed, then set
Reverse
Current
to
YES
, otherwise set to
NO
.
•
If the voltage measurement terminals are reversed, then set
Reverse
Voltage
to
YES
, otherwise set to
NO
.
