Calibrating the Voltage Probes

To fully meet user specifications, you need to adjust the

voltage probes for optimal response. The calibration

consists of a high frequency adjustment and a dc

calibration for 10:1 probes and 100:1 probes. The probe

calibration matches the probe to the input channel.

This example shows how to calibrate the 10:1 voltage

probes:

Display the input A key labels.

Open the PROBE ON A menu.

If the correct probe type is already

selected (yellow shaded) you can

continue at step 5.

ENTER

Select Probe Type: Voltage, and

Attenuation: 10:1.

Open the PROBE ON A menu again.

Select PROBE CAL…

it is necessary to connect both the hook clip and

the zero reference contact.
