Klein Tools Multimeter Test Kit contains Cat. No. MM320 (Digital Multimeter), Cat. No. NCVT1P (Non-Contact Voltage Tester) and Cat. No. RT110 (Receptacle Tester). The MM320 measures DC current, AC/DC voltage and resistance. The NCVT1P automatically detects standard voltage in cables, cords, circuit breakers, lighting fixtures, switches, outlets, and wires. The RT110 detects the most common wiring problems in standard receptacles.Features Identifies open ground, open hot, open neutral, hot/ground reversed; it does not indicate quality of ground, multiple hot wires, or a combination of defects NCVT1P has a high intensity, bright red LED that illuminates and an audible tone when voltage is detected from 50 to 1000 VAC power operating range Test leads included for Cat. No. MM320; batteries included for Cat. Nos. NCVT1P and MM320 MM320: Low Battery Indicator; NCVT1P: Pocket Clip Non-Contact Voltage Tester Cat. No. NCVT1P has a bright green LED to indicate the tester is working; it changes to red and audible tones sound when voltage is detected MM320 multimeter tests continuity with visual and audible continuity indicators Multimeter measures up to 600V AC/DC voltage, 10A DC current and 2MOhms resistance Receptacle tester Cat. No. RT110 detects wiring configurations and indicates correct wiring, and identifies common wiring faults Warnings Do not use equipment during electrical storms or in wet weather, and do not use if equipment appears to be damaged. Read, understand and follow all instructions, cautions and warnings attached to and /or packed with all test and measurement devices before each use. Before each use verify meter operation by measuring a known voltage or current. Do not attempt to measure resistance or continuity on live circuits.
