External Voltage Display

If there is a dangerous external voltage present on test terminals prior to a test
or during it, the warning message “EXTERNAL VOLTAGE!“ will appear on the
display and the start of the measurement will be blocked. Remove the external
voltage!

If an external voltage is applied to test terminals during the test in R
INS
function,
wrong measurement values may be displayed.
Testing Appliances
WARNINGS

Before starting the tests, you must familiarize yourself with the DIN VDE 0701-
0702 "Testing after repairs, alteration of electrical equipment - re-testing of
electrical devices".

Before commencing the tests, you are strongly advised to make reference to the
local regulations and standards for safety at works regulations and any relevant
publications from the Health and Safety Executive.

The DUT (Device Under Test = Appliance) must be switched on for all tests
(mains switch must be turned ON even if the DUT is disconnected from mains
voltage e.g. in R
PE
, R
INS
and I
SUB
tests).

When conducting tests do not touch the DUT as some tests involve higher
voltages and higher currents.

Do not touch the test specimen during the measurements, as a high risk may
arise in the case of faulty test specimens.

The tests should only be performed by competent persons who are familiar with
the requirements of the type of tests suitable for portable appliances.

It is potentially hazardous for both, user and the DUT if the wrong type of tests
be undertaken or if testing is carried out in an incorrect sequence.

It is important that you fully understand the various tests required and how they
should be performed.

The appliance must have passed the visual inspection, the protective earth bond
resistance test (PC I appliances) and the insulation test (in this sequence) prior to
any other test. If any of these tests fail further testing must be stopped and any
faults must be fixed.

During the earth leakage current test (I
PE(

)
), the touch leakage current test (I
T
)
and the function test (load power/current (P/I
L)
), the DUT will be energized at
mains voltage. For this purpose, switch on the DUT. DUT driven by motors or
equipped with heating elements may present a danger for the person testing or
others (comply with the user’s manual of the DUT!). Please ensure that the DUT
is in a safe condition to run and secure prior to testing.
Please remove external voltage from any test terminal
immediately if “EXTERNAL VOLTAGE!” warning is displayed.
