12. Carrying out the Integrated Automatic Test
Test samples already existing in a database can be tested rapidly by means of the automatic test.
The sequence described here applies to an already existing database (name), customer (name)
with registered test samples (ID no.). After pressing <Automatic Test> in the start menu, select the
following in the menu displayed:
- Selection of the database (name), only specific customers!
- Selection of the customer (name), only specific test samples!
- Selection of the test sample (ID no.), depending on the customer / database!
- Selectthetestsampleinthe"IDno."lineandmarkitbymeansoftheinputstylus.
Now, the menu of the selected test sample opens. The values are highlighted in grey colour and
cannot be modied in this menu!After pressing the <Start> button, rst the "Visual Inspection"
menuisdisplayed.Conrmitbypressingabutton.Afterapositivetestandpressingabutton,a
connection test is started. The test is intended to determine whether a dangerous contact voltage
is applied, whether a test sample is connected and to make sure that there is no short-circuit. After
a positive connection test, the measurement is started. In case of a negative connection test (e.g.
open switch), an information message is displayed. The individual tests (depending on the pre-set-
tingofthetestprocedure)aredisplayedsubsequentlyandpartlyhavetobeactivatedorconrmed
by pressing the <Start> button (also see description of the individual measuring types, chapter 8). In
case of faulty individual results that are dangerous, the measurement will be interrupted immediate-
ly. By pressing the <Pause> button, it is possible to interrupt measurement so that e.g. the test cable
with the alligator clip or probe tip can be connected to another measuring point without resulting in
incorrect measurements / indications.
Attention!Themainsvoltageappliedtothetestsamplewillpersistduringthe"Testinterrupted"mes-

results by pressing <Meas. Value> and to save them by pressing <Save>, <Yes>). The measuring
data will be stored in the selected database (name) and can be read out via a PC.
