Simpson 270 volt-ohm-milliammeter Series 5RT

辛普森 270 型 系列5RT 三用電表，RT型號是代表有小拉門的外箱

至今(2017)原廠仍在銷售的機型, 但似乎大家仍比較喜歡上一代的260系列.

This member of the 260 family has a better than 30% improvement in voltage and resistance accuracy compared to the standard 260-8 Series, perfect for more critical measurements.

DC voltage accuracy is ±1.25% full scale; AC voltage accuracy ±2% full scale; and Resistance accuracy ±1.5 º of arc.  The 270-5 comes with batteries, manual and test leads with alligator clips;

the 270-5RT also includes a built-in rolltop carrying case.

• Higher accuracy specifications for more precise measurements
• Self-shielding taut-band meter movement provides added shock resistance
• Rugged phenolic case with reinforced walls for maximum durability
• Reverse recessed safety jacks prevent operator and tool contact with electrical connections
• Large, tri-colored dial with mirrored scale to prevent parallax error
