4. The meter will show the approximate forward voltage
of the diode. If the connections are reversed, “1” will be

reinsert the battery into the case top. Dress the battery leads so
that they will not be pinched between the case bottom and case
top.
4) The meter is protected by fuse:
A) mA: F0.5A/600V Fast, Breaking capacity is 10KA,

B) 10A: F10A/600V Fast, Breaking capacity is 10KA,
dimensions are 20 x 5mmШ .
