In the first Menu “Connection”, the available mains voltage and the N and PE conductor
terminal are displayed.
7.1 AC Connection
NOTE!!!
• If the voltage L1 < 207 V or L1 > 253 V no proper measurements can be
made.
If the message “PE>30” appears it is most probable that the PE conductor is not connected to
the mains power socket. It may also happen that the PE conductor is connected but that it is
hazardous live (test using the fingercontact)! For checking the PE conductor refer to the
chapter “Mains Connection” above.
8 Display and Menu Structure
The display allows a comfortable menu based testing sequence, shows all measuring
functions, limits and values. The menu structure is documented in a separate document
“SAFETYTEST 1ST-Menu Structure”. It is kept up to date together with the software.
9 Taking the Tester into Operation
9.1 Visual check
• Observe the safety precautions of chapter 1.
• Check the mains connection, tester and accessories
• Observe all warning markings on the tester mains cord and accessories!
9.2 Connecting the tester to the mains system
• The tester is supplied from the mains input.
9.3 Starting the test
Follow the menu of the tester.
10 Testing Electrical Appliances
The tests required by the standards have been realised by the internal testing sequences.
Before starting a test the appliance has to be classified in the profile menu.
After repair, modification and after repetitive testing electrical appliances have to provide a
degree of safety to the user which is comparable of that of brand new appliances. Whether
the safety is given can be tested according to the applicable standard. The following tests are
to be performed in the given order. Each test step must have been passed before proceeding
to the following step:
• Visual inspection
• Earth bond test
• For class I appliances test of the insulation resistance and or the earth leakage
current or the substitute leakage current.
• For class II equipment as well as for accessible conductive parts not connected to PE
of class I equipment, the insulation resistance and the touch current or the substitute
leakage current.
• Functional Test
Notes:
Before performing a leakage test on class I appliances the earth bond test has to be passed.
