5.5.2 Delete the Gross Error Value

During the measuring process, if the deviation between the measured value
and standard value is too big before the mean value displaying, the current
measured value can be deleted by press “DEL” button, and the current value
would be neither stored nor in averaging, the impact times minus one.

5.6 Average Value

Normally, the measurements should be the average value of 3-5 times
testing results.After setting the impact times, the impact times reach the
setting value, will display the average value and the symbol

Ave

.The

interface of the average value as following:

5.7.1 Storage Testing Result

Press “MEM” storage button to set the saving function, the “S” symbol will
be shown on the display.
The tester will save the testing results automatically, including 7 testing
results and 1 average value each group, and total 100 groups can be stored.
After storing a group, the storage flag is off.
(Note: During the current group test, before the average value is displayed,
press “MEM” storage button to store the group of data)

5.7.2 Reading

In saving status, press and hold “MEM” storage button to enter the reading
mode and the symbol

R

will be shown on the display (see Figure 5.8).

At the same time, the first impact value in the recently saved groups will be
displayed, press

up

and

down

button to read the saved testing

value.Then press (or long press) “MEM” storage button to quit the mode of
