Leakage current tester 92-4A / 92-4D / 92-2E
MENU SYSTEM
Illustr. 4.7: Menu - Basic settings II
supply voltage is not activated. Mind the correct connection of the
external supply!
Mains supply check "no max./max +20%"
- Monitoring of the supply
voltage (at supply internally or externally). For test objects with auto-
matic voltage regulation the adjustment of the output voltage is set with
a tolerance of +3 V.
no maximum
- only monitoring on underrun
max +20% -
reports additionally the exceeding of the predefined
output voltage at more than 20%.
Supply IUT - "Internal / External"
Internal mains
- the output voltage (supply for item under test) is
generated by the internal transformer unit.
External mains
- the output voltage (supply for item under test) is
generated by an external device and supplied via the terminals
X4.1, 4.2, 4.3 at the rear of the unit (see also Chapt. 3.5).
Depending on the regulatory standards following switch-overs
are possible:
Internally/externally
for EN50144-1, EN60335/IEC60335,
EN60598, EN60601, EN60950, EN61029-1
Internally/externally AC or DC
for EN60065, EN61558
Internally/externally AC sinusoidal
, AC not sinusoidal or
DC
for EN61010.
The activated supply is shown as identification parameter in the lower line
of the status display.
Min load current "0.0 .... 14.9 A "
- enter the minimum current which
the item under test has to carry. If this value is not reached a contact
fault is assumed and a fault message is displayed. If "0.0" is en-
tered the contact monitoring is not active.
Chap. 5.1 describes the input of values.
