Figure 3-56: Re-use Probe Calibration Data Menu
If the
Re-use Probe Calibration data?
menu is displayed, you can choose one
of the following options:
Press OK Use Existing Data (side) to
use
the Probe Cal data last stored
to compensate the probe.
Press OK Erase Probe Cal Data (side) to
erase
the Probe Cal data last
stored and use the probe uncompensated.
Press CLEAR MENU on the front panel to
retain
the Probe Cal data last
stored and use the probe uncompensated.
NOTE
If the
Re-use Probe Calibration data
menu is displayed, do not
select OK Use Existing Data if the probe currently installed is not
of the same impedance stored for the Probe Cal. For example, if
the last Probe Cal stored for a channel was done with a passive
50 probe installed, do not install a passive 1 M probe and select
OK Use Existing Data
if the menu appears. If you do so, most of
any signal you attempt to measure will not be coupled to the input
channel because of the probe to oscilloscope impedance mismatch.
Table 3-6 shows the action the oscilloscope takes based on the probe con-
nected and user operation performed.
