This shock resistant analog multimeter gives an audible beep to verify circuit continuity.
The SP21 multimeter is designed for low voltage circuit analysis and must not be used to measure high power voltage lines. The meter is a taut-band type meter with zero center for ±DCV measurements. The SP21 can measure both ACV and DCV as well as resistance and capacitances with a 3% full-scale accuracy. The SP21 features a continuity test function with a buzzer alarm that sounds at less than approximately 10Ω.
The device has a protective case with built-in kickstand, made using fire retardant material that also provides protection against drop shocks, and a (250V/0.5A) fuse with a blowout capacity of 300A to protect its internal circuitry.
Includes meter, one set of test leads and instruction manual.
