GENERAL SPECIFICATIONS
Klein Tools MM600 is an automatically ranging digital multimeter that
measures AC/DC voltage, AC/DC current, and resistance. It can also
measure temperature, capacitance, frequency, duty-cycle, test diodes
and continuity.
• Operating Altitude: 6562 ft. (2000m)
• Relative Humidity: <90% non-condensing
• Operating Temp: 14°F to 122°F (-10°C to 50°C)
• Storage Temp: -4°F to 140°F (-30°C to 60°C)
• Accuracy: Values stated at 65°F to 83°F (18°C to 28°C)
• Temp Coeff cient: 0.1 x (Quoted Accuracy) per °C above
28°C or below 18°C, corrections are required when ambient
working temp is outside of Accuracy Temp range
• Dimensions: 7.02" x 3.54" x 2.10" (178.3 x 89.9 x 53.3 mm)
• Weight: 14.6 oz. (414 g)
• Calibration: Accurate for one year
• Standards: Conforms to: UL STD 61010-1, 61010-2-030,
61010-2-033.
Certified to: CSA STD C22.2 # 61010-1,
61010-2-030, 61010-2-033.
IEC EN 61010-1, 61010-2-030,
61010-2-033, 61326-1.
• Pollution degree: 2
• Accuracy: ± (% of reading + # of least significant digits)
• Drop Protection: 6.6 ft. (2m)
• Ingress Protection: IP42 (except test lead jacks, see WARNINGS)
• Safety Rating: CAT IV 600V, CAT III 1000V, Class 2,
Double insulation
CAT III: Measurement category III is applicable to test and
measuring circuits connected to the distribution part of the
building’s low-voltage MAINS installation.
CAT IV: Measurement category IV is applicable to test and
measuring circuits connected at the source of the building’s
low-voltage MAINS installation.
• Electromagnetic Environment: IEC EN 61326-1. This
equipment meets requirements for use in basic and controlled
electromagnetic environments like residential properties,
business premises, and light-industrial locations.
Specifications subject to change.
