NOTE
This means that the 3522-50 is operating
outside the range for which the accuracy
of the measured values can be assured.
The Initial screen is the screen which is initially displayed when the power
to the 3522-50 unit is turned on.
The monitor display on this screen enables the user to perform testing while
checking the values of all the test conditions. (The monitor display varies
according to the test signal level setting.)
Even if the 3522-50 unit is being used outside the limits of its specification,
test values are sometimes displayed. In this case, the following type of
indication appears on the display.
In this case, you should consider the following possible causes, and you
should either change the test conditions while checking the accuracy assured
ranges (with reference to Section 7.5, "Test Accuracy"), or you should
consider the measured values as values for reference only, because their
validity is somewhat doubtful.
Perhaps the test signal controlled level is too low.
Increase the test signal level.
Perhaps the present test range (if ranging is set to HOLD) is not suitable.
Either set the test range to the most suitable one by using AUTO ranging, or
change the test range manually.
When powering on again, the screen when the power has been turned off on
the following screens is displayed.
Initial screen, Comparator screen, Scaling screen, Magnification screen,
Continuous test screen
