Leakage current tester 92-4A / 92-4D / 92-2E
MENU SYSTEM
Peak value measurement:
Auto / 10 mA - the measuring starts at the highest measure-
ment range downwards to the lower ranges.
Electric burn effect of touch currents and measurements according
to EN 60065 at current
I1
:
10 mA fixed
Common return connection (FE) - "Yes / No"
- if the IUT has its own
common return connection of the application part then it has to be
connected with the
FE
-socket at the rear of the measurement instru-
ment. During the test the common return is then included. Application
for medical equipment only, according to EN 60601-1.
Yes
- there is a common return connection available and is
connected with the measurement instrument
No
- no common return connection available
Signal Part (SIGNAL) - "Yes / No"
- indicates whether the item under
test has a separate signal device which has to be supplied with a sep-
arate auxiliary supply voltage during the leakage current measurement.
The parameter refers to the connection "Signal". During the test run an
auxiliary voltage is applied to the terminal
Signal.
Yes
- a signal device is available and is connected with the
measuring instrument.
No
- no signal device available.
Parameter only visible at
GAS
and at
PHS
if PE fault simulation „no
active“.
2. measurement system (MD2) - "Yes / No"
Yes
- the add. measurement circuit (Optional feature) is activated
No
- the add. measurement circuit (Optional feature) is deactivat-
ed
The device is not really equipped with a second measuring system. The
measurement input of the integrated measuring system is changed over
by the software to the input lab terminals Vi and PAT2. The device is
measuring the LC-current via the lab terminals Vi and PAT2. See also
measuring circuits in the appendix.
