Technical safety check – step by step
For simplification the device to be tested is referred to below as the "test
specimen".
Safety information
WARNING! For safety reasons (personnel protection) the test specimen should
generally be operated by a suitable isolating transformer.

An exceptional case is the tests for grounded conductor resistance,
ground leakage current, and patient leakage current, in which the test
specimen is supplied with current via the safety tester.
ATTENTION! In the event of a fault occurring in the test specimen or individual com-
ponents during the technical safety check the test steps taken so far no
longer apply. 
Remedy the defect and repeat the technical safety check from the
beginning.
ATTENTION! The specifications made in this chapter for the test programs allow the
service technician to perform the safety check. In addition, the test pro-
grams provide a number of diagnostic and inspection options in the
unit; detailed descriptions are available in the repair instructions. Erbe
expressly states that the full functional range of the test programs may
not be used without precise knowledge of the test programs.
IMPORTANT! It is assumed that the user knows how to operate the test specimen,
the test equipment, the measuring equipment, and auxiliary test equip-
ment. The test instructions only apply in conjunction with the relevant
test steps.
IMPORTANT! Test equipment, measuring equipment, and auxiliary test equipment
(cables, test boxes, etc.) are listed separately at the beginning of each
test unit. Where Erbe article numbers are specified, only original Erbe
test equipment, measuring equipment, and auxiliary test equipment
may be used.
IMPORTANT! The test report for the technical safety check can be requested from
Erbe Technical Service Tübingen. For the address see address sheet on
last page.
