DC Voltage Accuracy Test

WARNING.

Dangerous voltages will be present on the calibration generator output terminals and connection cables. Always

verify that the generator is in the standby mode before you make any connections to the generator.

1.

Connect the test setup as shown. (See Figure 3.)

Figure 3: Setup for DC voltage accuracy test

2.

Press the Ch 1 button once (for channel 1). The menu that appears on the bottom of the screen allows you to change
settings. Set all channels on the oscilloscope to the settings below:

Probe Type: Voltage, Attenuation: 1:1

Input Options: Polarity: Normal, Bandwidth: 20 kHz (HF Reject)

Measure: Measurement on, V dc

Acquire Options: Glitch: Off, Memory: Short, Average: Off, Waveform: Normal

Ground level centered vertically

Horizontal scale: 10 ms/div

3.

Set the oscilloscope to display Channel 1.

4.

Set the oscilloscope vertical sensitivity to the

fi

rst value in the table. (See Table 4 on page 8.)

5.

Set the calibration generator to the

fi

rst value in the table.

6.

Enable the calibration generator output.

7.

Verify that the measured output voltage on the oscilloscope is within the range shown under the appropriate column.

8.

Continue through the test values remaining in the table for Channel 1.

9.

Set the generator output to 0 V and to standby.

10.

Repeat steps 3 through for the remaining channels on the oscilloscope. Trigger on the appropriate channel as needed.
