It has a wide operating frequency range from about 1 Hz (depending on load impedance) to 200 kHz. It also has an A-weighting filter that can be switched in or out.\u003c\/p\u003e\n\u003cp\u003eThe 12AL can be powered by either two internal AA alkaline batteries or an external 3–6 VDC power source. Both the AA batteries and the AB0005 6 VDC power supply are included.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch2 class=\"h4\"\u003eKey Specifications\u003c\/h2\u003e\n\u003cdiv
