Current measurement: In the A range, 250 VDC/VAC rms max. and 20 A
AC / DC max. for 30 seconds duration with a sub-
sequent cooling phase of at least 15 minutes;
overload protection 20 A 250 V quick-blow cera-
mic fuse (dimensions: 6 x 30 mm)
In the mA range, 250 VDC/VACrms max. and
500mA AC/DC max.; overload protection 0.5 A
250 V ceramic quick-blow fuse (dimensions: 5 x 20
mm)
Attention!!!
The measurement functions diode test, "SIG OUT" (signal generator
output), logic test and capacity measurement are not protected against
overload or excessive input voltage(s).
Exceeding the maximum permitted input levels can damage the measu-
ring instrument and/or endanger the life of the user.
