TH2829X Series Operation Manual Chapter 3 Introduction to [MEAS]
33
The deviation currently displayed is the difference between the test value of
the DUT and the preset reference value. The formula of calculating ΔABS is as
below:
ΔABS=X-Y
Where, X is the test value of DUT
Y is the preset reference value.
 Δ% (Percentage deviation mode)
The deviation currently displayed is the percentage of the difference between
the test value of DUT and the preset reference value divided by the reference
value. Its calculating formula is as below:
Δ%=(X-Y)/Y*100[%]
Where, X is the test value of DUT.
Y is the preset reference value.
Operation steps for setting deviation test function
1) Move the cursor to the REF A zone to input the reference value of the primary
parameter, the following soft key will be displayed.
 MEAS
When the reference component is connected with the test terminal, you
should press MEAS. Then TH2829X will test the reference component and the
test result will be automatically input as the value of REF A
.
2) Use MEAS or numeric keys to input the reference value of primary parameter.
3) Move the cursor to the REF B to input the reference value of the secondary
parameter, the following soft key will be displayed.
 MEAS
When the reference component is connected to the test terminal, you should
press MEAS. Then TH2829X will test the reference component and the test
result will be automatically input as the value of REF B
.
4) Use MEAS or numeric keys to input the reference value of the secondary
parameter. If the reference values of primary and secondary parameters have
been set in steps 2), you can skip this step.
5) Move the cursor to the DEV A zone, the following soft keys will be displayed:
 ΔABS
 Δ%
 OFF
6) Use above soft keys to se the deviation mode of the primary parameter.
7) Move the cursor to the DEV B zone, the following soft keys will be displayed.
 ΔABS
 Δ%
 OFF
8) Use above soft keys to se the deviation mode of the secondary parameter.
