E Verify that the device under test is electrically dead. External voltages
would falsify the measured result!
E Set the function selector switch (6) to “ Ω ”.
E
Connect the device under test as shown.
l 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"
l After a fuse has blown, eliminate the cause of the overload before using
the meter again !
l
Replacement of the fuses is described in section ’’ 18. Maintenance’’.
9.1 AC current measurement with (clip-on) current
transformer( )
E
Current to voltage clamp with ratio 10 mA : 1mV is used to
measure the current upto 300 A AC with this function
E
Set rotary knob at position V(DC+ Yellow)k
“measurement with clip-on
transformer” mode.
E
Connect Clamp Output probes to “ ^ ” and “ ” input terminal of this
meter.
E It has two ranges i.e. 30.00 A and 300.0A. Measurement is possible
with both auto ranging and manual ranging.
