1. Measure range coupled to source range when simultaneously sourcing and measuring current.
2. As measured by precision digital multimeter. Use closest possible value, and modify reading limits
accordingly if necessary. See
Measurement limit calculations
(on page B-4).

2. Turn the output off and change connections as shown adding the 0.5
Ω
250 W resistor (see the
figure titled "Connections for 1.5 A and 3 A current ranges" in
Current source accuracy
(on page
3. Select the DMM volts function.
Repeat steps 4 through 6 for the 3 A range (Model 2601B/2602B/2604B) or 1.5 A range (Model
2611B/2612B/2614B/2634B/2635B/2636B). Calculate the current from the DMM voltage reading
and characterized 0.5
Ω
resistance value.
4. For the Model 2602B/2604B/2612B/2614B/2634B/2636B, repeat the above procedure for the
other channel.
