Calibration
2-15
17. Note and record the DMM reading, and then adjust the display to agree with the
DMM reading. Once again, the maximum adjustment is within ±1% of the present
range.
18. After adjusting the display to agree with the DMM reading, press ENTER to com-
plete calibration of the present range.
19. Press EXIT to return to the normal display, and then select the 100
μ
A source range
using the EDIT and up RANGE keys. Repeat steps 2 through 18 for the 100
μ
A
range.
20. After calibrating the 100
μ
A range, repeat the entire procedure for the 1mA through
1A ranges using Table 2-4 as a guide. Be sure to select the appropriate source
range with the EDIT and up RANGE keys before calibrating each range.
21. After calibrating the 1A range, connect the 1
Ω
characterized resistor and DMM to
the Model 2425 INPUT/OUTPUT jacks, as shown in Figure 2-3.
22. Select the DMM DC volts function.
23. Repeat steps 2 through 18 for the 3A range using Table 2-4 as a guide. When enter-
ing the DMM reading, use the calculated current as follows: I = V/R, where V is
the DMM voltage reading, and R is the characterized value of the 1
Ω
resistor.
