Level Monitor Function
Description
The level monitor function allows you to monitor the actual voltage
level across the device under test or the actual current level though
the device under test. The voltage monitor value is only displayed
on the MEAS DISPLAY page at Vm monitor area. The current
monitor value is only displayed on the MEAS DISPLAY page at Im
monitor area.
Note
The correction function interacts with the level monitor function. So
the monitor value maybe changed by the correction data change or
the OPEN/SHORT/LOAD correction ON/OFF condition change.

Deviation Measurement
Function
Description
The deviation measurement function allows you to display the
deviation value instead of the actual measurementvalue. The
deviation value is the value calculated by taking the dierence
between the actual measurementvalue and a previously stored
reference value. This function is useful when the change of a
component's value versus changes in temperature, frequency, bias,
etc. are being observed. Deviation measurements can be made for
either or b oth primary parameter and/or secondary parameter
measurements. There are twotypes of deviation measurements.
