DVM Measurement Accuracy

This test verifies the DVM measurement accuracy. Connect all equipment as shown in figure B-1D.

Action

Normal Result

1.

Turn off the dc source and connect the external DMM and the
external power supply to the DVM inputs as shown in figure B-1D.
Connect only the negative output lead of output 1 to the DVM
inputs. Then turn on the dc source and select Output 1.

2.

Set output 1 to zero volts and the external power supply to 25 volts.

Output voltage near 0 V

3.

Record the external (3458) DMM reading (Dvpos) and the internal
DVM reading.

Internal DVM reading should be

within positive voltage limits.

(see Table B-3, B-4).

4.

Set output 1 to 15 V and repeat step number 3.

Internal DVM reading should still be

within positive voltage limits.

(see Table B-3, B-4).

5.

Reverse the leads of the external power supply to the DVM inputs.
Keep all other connections the same.

Output voltage near 15 V

6.

With output 1 set to 15 V, lower the voltage on the external power
supply until the external (3458) DMM reads

−

4.5 V.

Output voltage near 15 V

7.

Record the external (3458) DMM reading (Dvneg) and the internal
DVM reading.

Internal DVM reading should be

within negative voltage limits.

(see Table B-3, B-4).

8.

Set output 1 to zero volts and repeat step number 7.

Internal DVM reading should still be

within negative voltage limits.

(see Table B-3, B-4).
