19.
Press
ENTER
.
20. The unit will then prompt you for the DMM reading:
CAL 50mA CHAN 1
READ1 45.0000 mA
21. Note the DMM voltage reading, then calculate the current from that reading and the actual
4
Ω
resistance value: I = V/R. Adjust the Model 2308 current display value to agree with the
calculated current value, and press
ENTER
.
22. Disconnect the 4
Ω
resistor, then connect the 3 k
Ω
resistor in its place (use the connections
shown in
Figure 13-3
).
23. Make sure the DMM DC volts function and auto-ranging are still selected.
24. The unit will prompt you for Channel #1 5 mA full-scale calibration:
CAL 5mA CHAN 1
ALL READY TO DO?
25.
Press
ENTER
.
26. The unit will then prompt you for the DMM reading:
CAL 5mA CHAN 1
READ1 4.50000 mA
27. Note the DMM voltage reading, then calculate the current from that reading and the actual
3 k
Ω
resistance value: I = V/R. Adjust the Model 2308 current display value to agree with
the calculated current value, and press
ENTER
.
