circuit current of 25 A by a fuse 1.6 A/500 V in conjuction, with power
diodes. The cut-out capacity of the fuse is 20kA at a rated voltage of
500V
~
and ohmic load.
The 3 A and 10 A current measuring ranges are protected by a 16A/
600V fuse. The cut-out capacity of the fuse is 100 kA at a normal
voltage of 600 V
~
and ohmic load.
Caution:
The measuring ranges 3A and 16 A of ZIEGLER Multi 13S are not protected
by a fuse!
A blown fuse is signalled on the LCD the instant a measured quantity
having a voltage of more than 4 V is applied to the corresponding
connection sockets. Then, the digital display (9) shows the word
" FUSE"
After a fuse has blown, eliminate the cause of the overload before
using the meter again !
Replacement of the fuses is described in section ’’ 18. Maintenance’’.
9.1AC current measurement with (clip-on) current transformer
9.1.1 T ransformer output mA/A
Caution:
If current transformers are operated with an open circuit on the secondary
side, e.g. due to defective or disconnected leads, a blown fuse in the
meter, or a wrong connection, dangerously high voltages can occur at
the connectors. Therefore, verify that the current circuit of the multimeter
and secondary winding of transformer connected to the multimeter
forman intact circuit. Connect the transformer to the sockets
and mA
and/or A.
The maximum permissible operating voltage is the nominal voltage of
the current transformer. When reading the measured value, take into
account the transformer ratio and the additional error in indication.
Transf ormer output ZIEGLER Multi 12S
The ZIEGLER
Multi
12S shows the switching position ’’ A’’ and the
corresponding sockets. Connect to this socket a (clip-on) current
transformer with a transmission ratio of 1000:1; then the measured values
are displayed directly in the ’’A’’ range.
9.1.2 T ransformer output V
Many transformers have voltage output (refered as mV/A)
The secondary output must therefore be connected to the connection
sockets
and V.
10. Resistance measurement
Verify that the device under test is electrically dead. External voltages
would falsify the measured result!
Set the function selector switch (6) to " W".
Connect the device under test as shown.
