After switching ON,
dito
starts a self test routine to check the
basic function of the unit including the high voltage power supply.
The R/C discharge parameters of the module are displayed in the
lower line.
In case that there is no discharge module connected,
dito
will
show the message
No Discharge Module
.
By pressing the trigger button once again you can get into the

Setup
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
polarity can be changed. The value
U per
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.

1.3 dito: Starting with Easy ZAP
Easy ZAP
Select the menu Easy ZAP by pushing function key . With
Easy ZAP only predefined standard levels are tested.
Before the test is started, the operator has to select
the discharge mode,
CD
contact discharge ( discharge tip 3a) or
AD
air discharge ( discharge tip 3b)
the trigger mode,
Single
: single discharge,
Auto
: push once the trigger button [9] ,
Cont
: trigger button must be pressed all time
Rep
: the repetition rate of the discharges
Functions
Select : By pushing a function key several times, the operator
can change between different modes,
e.g. Trigger : Single Auto Cont .
Start : After all parameters are selected, the operator can
make dito ready for testing by pushing the function key
Start . The test itself is controlled by the trigger
button [9].
-
During the test, you can change polarity by
pressing .
-
With the function keys the op-
erator can change the test level.
-
Pressing the function key Stop will stop the test
routine.

1.4 dito: Easy ZAP menu
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
To enable the beeper select:
Hardware setting Key Beep = ON / OFF
Single-beep = Input confirmation if Key beep is ON
Double-beep = Double beep always indicates warnings or failures e.g.:
- No discharge Module
- No discharge relays available
- Battery voltage too low to generate high voltage.
- Pre-discharge ( air discharge occurred before
the selected test voltage was reached)
- Test voltage not reached or not correct
Triple-beep = Test is finished;
dito
has shut down (switched OFF)
The Trigger button [ 9 ]
To switch ON: Press the Trigger button once
To switch OFF: Press the Trigger button [9] for 3s
Exception ( dito is in Start Mode )
To change the menus: Press the Trigger button once
To release discharges Single: Press Trigger button once
Cont : Discharging as long as the Trigger
button is pressed.
Auto: Press Trigger button once, the test runs
automatically. Pressing Trigger button
again stops the test procedure.

Quick Zap Menu
In Quick Zap Menu all parameters can be selected individually.
During a running test :the voltage can be increased by pushing
decreases the voltage
increases the voltage
changes the polarity
Test Routines Menu
With the user can enter the menu Test Routines. 8 prepro-
grammable test routines can be stored. dito is delivered with 6
standard routines.
The test routines can be programmed in the ditoControl soft-
ware which is available as an option. Via the optical interface
the test routines can be downloaded to dito. More information
please read in the dito and ditoControl manual.
Evaluation
With the user can enter the menu
Evaluation
. This menu
can be used to check the DUT for most sensitive test points.
The preferred method to find these test points is air discharge
AD
( discharge tip 3b ). Air discharges are continuously gener-
ated with a maximum repetition rate of 20Hz.
Contact mode
CD
( discharge tip 3a ) is selected for long dura-
tion tests to apply a large number of repeatable discharges to a
specified test point. The preferred Trigger mode is
Auto
or
Continuous
.
All parameters can be selected individually. During the evalua-
tion procedure, the operator can change the polarity and the
test voltage.
Setup
For detailed information related to the setup menu please read
the dito manual.
Firmware updates
Firmware updates can be downloaded via the optical interface.

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.
