14-8 Calibration
9. At this point, the unit will prompt for 5A Channel #1 full-scale calibration output:
CAL 5 A CHAN 1
SET 1.90000 A
10. Using the edit keys, adjust the set value to 1.9000A, then press ENTER. The unit will
prompt you for the DMM reading, which calibrates the 5A current limit for Channel #1:
CAL 5 A CHAN 1
READ1 1.90000 A
11. Note the DMM voltage reading, then calculate the current from that reading and the
actual 4Ω resistance value: I = V/R. Adjust the Model 2306 current display value to
agree with the calculated current value, and press ENTER.
12. The Model 2306 will prompt for another DMM reading, which is used for 5A
measurement calibration of
Channel #1:
CAL 5 A CHAN 1
READ2 1.90000 A
13. Again, calculate the current from the new DMM reading and 4Ω resistor value. Adjust
the 2306 current display reading to agree with the new current, then press ENTER.
14. F
or Model 2306/2306-VS: Connect the 3kΩ resistor in place of the 4Ω resistor (Figure
14-3).
For Model 2306-PJ:
Leave the 4Ω resistor in place (do not change resistors)
(Figure 14-2).
15. At this point, the unit will prompt for an output on Channel #1.
For Model 2306/2306-VS: For Model 2306-PJ:
CAL 5 mA CHAN 1 CAL 500 mA CHAN 1
ALL READY TO DO? ALL READY TO DO?
16. F
or Model 2306/2306-VS: Press ENTER to output approximately 5mA.
For Model 2306-PJ:
Press ENTER to output approximately 500mA.
17. The unit will then prompt you for the DMM reading:
For Model 2306/2306-VS: For Model 2306-PJ:
CAL 5 mA CHAN 1 CAL 500 mA CHAN 1
READ1 4.50000 mA READ1 450.000 mA
18. Note the DMM voltage reading, then calculate the cu
rrent from that voltage reading and
actual resistance value. Adjust the Model 2306 current display value to agree with that
value, and press ENTER.
