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. 

Features:

• Drop shock proof taut-band meter
• ±DCV zero center meter
• Fuse and diode protection
• Battery check
• Tilt stand

Functions:

	Battery Check Battery voltage is measured and assessed by running a given current.
	Zero Center Meter (NULL) Moves the indicator of the analog tester to the center of the scale for measurement of positive and negative voltage.
	Capacitor Capacitor capacity (electrostatic capacity) is measured and expressed in the unit of F (farad), μF, etc.
	Drop Shockproof The meter element is furnished with a taut band and impact-resistant design enough to withstand a shock of drop.
	Continuity Buzzer The buzzer sounds when the measuring object is electrically conducting.
