Easy Zap is based on “Standard Test Lev-
els”. After pressing Start, the operator can
select the required test level with the func-
tion keys and with
the polarity can be changed.
Within Quick Zap the test voltage can be
changed with the function keys
while running a test. With buttons the

step can be selected in the Service Menu
under Setting. Evaluation
This test routine helps to search for most
sensitive test points at the DUT. The dis-
charges are released with a higher repetition
rate. This routine is normally not used for
final testing at the preselected test points.
The dito includes 8 standard routines, which
the operator can preprogram on his own by
using the „ditoControl“ software. The data
can be downloaded via the optical interface.
The Standard Routines will guide the user
through the complete test procedure.
Hardware and software settings are made in
this menu.
- The standard test levels for AD and CD
can be set.

In case of air discharge mode the discharge may occur at any voltage
depending on the distance between the discharge tip and the DUT. This
may happen if the discharge tip is too close to the DUT and the dis-
charge occurs during the charging up procedure of dito. Therefore dito
shows you the following messages:
Discharge occurred after the preselected test voltage was reached ( normal case)
Discharge occurred between 50% and 100% of the preselected test voltage
Discharge occurred between 0% and 50% of the preselected test voltage
Acoustical signals

Short manual for ditoControl software
(Version  1.20 )
ditoControl is not only a software to control dito and to perform ESD tests automatically, but it is a software
which manages the office work as well as the test itself. The following important steps are covered:
Office work (preparation of the test)
 Making „Test Notes“ as preparation for the real test
 Description of the DUT
 Specification of the test points based on a picture of the DUT.
 Description of functions and failure criteria of the DUT.
 Specification of the test parameters and the test routine
 Specification of auxiliary equipment and special test software used in this test.
 Print out of the Test Notes. This document is used to support the operator during the running test.
Comments which are important can be written into and can be added later on into the test report.
 Generation of test routines
 Based on the Test Notes the test parameters are fixed.
 Preprogrammed the test routines based on the data in Test Notes.
 The different test routines can be managed by ditoControl (library)
 Standard test routines and standard libraries can be built up.
 The complete test preparation is made. All data are available on the computer
Laboratory work.
 Make dito ready for testing.
 dito is connected to the computer and ditoControl is started.
 The preprogrammed test files are downloaded to dito. If necessary or useful all other test routines
which are available in dito can be deleted.
 The operator can only perform tests for which the related test routines are available. False operation by
the user therefore are not possible.
 The operator performs the test at the DUT.
 All test data of the actual test are stored in dito.
 In case of failures at the DUT the operator can set Fail-Flags, which also are stored in dito.
 Comments related to these Fail-Flags can be added manually to the Test Notes and can be later on
entered to the test report at the right place. All Fail-Flags are indicated in the test report.
Office work.
 The operator generates a test report.
 After the test is finished dito will be connected again to the computer. All test data stored in dito will be
uploaded and are the basis for the test report.
 ditoControl automatically generates the test report.
 The generated document can be converted into almost all other formats.
 Custom specific logos and pictures can be implemented.
 The documents and the used test routines can be directly emailed to other dito users or laboratories.
