Model 2308 Portable Device Battery/Charger Simulator User’s Manual
Section 13: Calibration
Figure 13-2
Connections for 5 A, 500 mA, and 50 mA current calibration
9. At this point, the unit will prompt for 5 A 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 1.9000 A, then press
ENTER
. The unit will
prompt you for the DMM reading, which calibrates the 5 A 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
4
Ω
resistance value: I = V/R. Adjust the Model 2308 current display value to agree with the
calculated current value, and press
ENTER
.
12. The Model 2308 will prompt for another DMM reading, which is used for 5 A 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 4
Ω
resistor value. Adjust the
Model 2308 current display reading to agree with the new current, then press
ENTER
.
14. The unit will now prompt you for Channel #1 500 mA full-scale calibration:
CAL 500mA CHAN 1
ALL READY TO DO?
15.
Press
ENTER
.
16. The unit will then prompt you for the DMM reading:
CAL 500mA CHAN 1
READ1 450.000 mA
17. 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
.
18. The unit will prompt for Channel #1 50 mA full-scale calibration:
CAL 50mA CHAN 1
ALL READY TO DO?
