3.3.7 Deviation test function
The deviation test function can replace the actual test value with the deviation value and display it
directly on the screen.The deviation value is equal to the current actual test value minus the preset
reference value.Using this function, it is convenient to observe the variation of the parameters of
the tested components with temperature, frequency and bias.The deviation testing function can be
used for the main or secondary parameters, or for the main and secondary parameters at the same
time.The instrument provides two kinds of deviation test methods as follows:
ΔABS mode (absolute deviation mode)
The current display deviation is the difference between the test value of the tested part and the set
reference value. Formula for calculating the deviation of ΔABS
As below
● ΔABS
＝Ｘ－Ｙ
Here
，
X:The measured values of the current measured parts.
Y: Preset reference values.
●Δ% mode (percentage deviation)
The deviation currently displayed is the percentage error obtained by dividing the difference
between the test value and the reference value set by the reference value. The formula for
calculating the deviation of_% is as follows:
Δ%
＝
(
Ｘ－Ｙ
)/Y ×100 [%]
Here
，
X:The measured values of the current measured parts.
Y: Preset reference values.
Deviation test function operation steps
Perform the following procedure to set up the deviation test function of the instrument.
1)Move the cursor to the reference A domain to enter the reference value of the main
parameter.The soft key area of the screen displays the following soft keys.
