DVM Tests
DVM Measurement Accuracy (calibration)
This test verifies the DVM measurement accuracy.
a. Turn off the dc source and connect the external DMM and the external power supply to the DVM
inputs as shown in figure B-1e. Connect only the negative output lead of output 1 to the DVM
inputs. Then turn on the dc source and select output 1.
b. Set output 1 to zero volts and the external power supply to 25 volts.
c. Record the external (3458) DMM reading and the internal DVM reading. The difference should be
within the positive limits specified for the DVM in Table A-3.
d. Set output 1 to 15 V and repeat step c.
e. Reverse the leads of the external power supply to the DVM inputs. Keep other connections the same.
f. With output 1 set to 15 V, lower the voltage on the external power supply until the external (3458)
DMM reads −4.5 V.
g. Record the external (3458) DMM reading and the internal DVM reading. The difference should be
within the negative limits specified for the DVM in Table A-3.
h. Set output 1 to zero volts and repeat step g.
