To test the dc calibrator

Figure 3-2

Set Aux Output to DC

Set the output voltage

Selecting DC in the Calibration Dialog

6Set the dc output voltage to +2.500 V using the Level spin box or the numeric keypad dialog.

You can access the numeric keypad dialog by clicking on the value in the Level box. Enter the values by clicking on digits, signs, and exponents in the keypad. Click Close when finished.

7The DVM should read near +2.500 V. Record the reading to four significant digits. V1 = __________.

8Set the level to -2.500 V using the Level spin box or the numeric keypad dialog.

9 The DVM should read near –2.500 V. Record the reading. V2 = __________.

10Subtract the second reading from the first reading, then divide the result by 5.

For example, if the first reading is +2.498 V and the second reading is -2.497 V, then

V1 – V2 2.489 – (–2.497)

-------------------= ----------------------------------------= 0.999

11The final result should be between 0.998 and 1.002. Record the result in the Performance Test Record at the end of the chapter.
