Calibrating the Voltage Probes

Repeat steps 2 and 3 and proceed as follows:

5

 

 

 

Select Probe Cal with the arrow

 

 

 

 

keys, then accept.

 

 

 

 

 

 

 

 

 

A message appears asking you whether to start the 10:1 probe calibration.

6 Start the probe calibration.

A message appears telling you how to connect the probe. Connect the red 10:1 voltage probe from the red input A jack to the red banana jack. Connect the reference lead to the black banana jack. (See Figure 50.)

7

 

 

Adjust the trimmer screw in the

 

 

 

probe housing until a pure square

 

 

 

 

 

 

wave is displayed.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The test tool automatically calibrates itself to the probe. During calibration you should not touch the probe. A message indicates when the DC calibration has completed successfully.

9 Return.

Repeat the procedure for the gray 10:1 voltage probe. Connect the grey 10:1 voltage probe from the grey input B jack to the red banana jack. Connect the reference lead to the black banana jack.

Note

When using 100:1 voltage probes, choose 100:1 attenuation to perform a HF adjustment. Automatic dc calibration is not possible with this probe type.

8

Continue with DC calibration. Automatic DC calibration is only possible for 10:1 voltage probes.
