Overview
The Simpson 260-8PRT is a professional-grade analog volt-ohm-milliammeter designed for field and workshop use. This model includes all the same features as the 260-8P but with a roll-top carrying case. The meter features taut band suspension and a mirrored dial to eliminate parallax errors, providing reliable analog measurements across 36 distinct ranges for voltage, current, resistance, and decibel measurements.
Key Features
- Additional relay overload protection circuit that is resettable and provides audible continuity checking
- Diode network protects the instrument from overload damage during use
- Taut band suspension with mirrored dial eliminates parallax errors
- Phenolic case with heavy reinforced walls for maximum durability and self-shielding taut-band for shock resistance
- Two-knob operation with ohms zero adjustment, AC-DC voltage selection, and continuity testing
- Full-size test leads with threaded probe tips and alligator clips included
Technical Specifications
DC Voltage ranges from 250 mV to 1000V with 2% full-scale accuracy and 20 kΩ per volt sensitivity. AC Voltage ranges from 2.5V to 1000V with 3% accuracy and 5 kΩ per volt sensitivity. Resistance measurements span from 0 to 20 MΩ across three ranges (Rx1, Rx100, Rx10K). DC Current ranges from 50 µA to 10A with 1.5% to 2% accuracy depending on range. AC current measurement up to 250A with optional clamp accessory. Five decibel ranges available: -20 to +50 dB (0 dB = 1 mW/600Ω).
Physical dimensions: 7″ H x 5.5″ W x 3.1″ D, weighing 3 lbs. Rated voltage: 1000V AC or DC maximum. Fuses: 1A @ 250V, 2A @ 600V.
