● Dust-proof and water-proof construction (IP54)
● Polarized terminal design prevents incorrect insertion of test leads
● Internal current-limiting resistor and fuse protect
E nhanced C onvenience
● Safe and simple

use, the current-limiting
COM
resistor and fast-blow fuse
protect against short-circuit conditions in the unlikely event of
catastrophic failure of the tester circuit: short-circuit current is
limited until interruption by the fuse, rated for up to 10 kA.
*If voltage is applied to the test leads while in the resistance measurement mode, as
long as it is within the measurement category (CAT III 600 V, or CAT II 1000 V),
protective components in the tester circuitry prevent the fuse from opening.
