The Jewell Instruments MS2 Analog Panel Meter delivers precise electrical signal indication across industrial and laboratory environments. This analog meter combines D’Arsonval movement technology with user-accessible zero adjustment and multiple configuration options to meet diverse measurement requirements.
## Technical Specifications
**Accuracy & Standards**
• DC meters: ±2% of full scale at 23°C
• AC rectified-type meters: ±3% of full scale at 23°C
• Compliant with ANSI C39.1
**Movement Types**
Three movement options address different application demands. Pivot & Jewel movements employ a compact, self-shielded D’Arsonval design with 100° deflection (100 µA range and above) or 90° deflection (below 100 µA range), offering excellent damping and shock resistance. Taut Band (TB) movements provide superior torque and damping with 100° standard deflection and enhanced shock immunity through unique suspension design. Core-Mag (CM) movements deliver 90° standard deflection.
**Electrical Characteristics**
Ammeter resistance: ±10% of stated value in ohms. Voltmeter resistance: ±5% of stated value in ohms. The 1½” meter input is 50 mVDC for use with external shunts (not supplied).
## Key Features
• External zero adjuster on cover with ±3% minimum adjustment range
• Zero positioning: standard left configuration; center, right, and offset available upon request
• Precision molded black thermoplastic barrel and flange case; Lexan available on special order
• Optically clear molded Plexiglass concave cover reduces glare and improves readability
• White metal dial with sharp division marks and black printed numerals
• Standard black lance pointer; knife edge, tubular, red, or white pointer options available
• Threaded stud-type terminals standard; solder lugs available upon request
## Typical Applications
Continuous signal monitoring in industrial control systems, laboratory measurement, panel-mounted indication across AC and DC electrical circuits, and demanding environments requiring shock and vibration resistance.
## Compatibility & Integration
1½” meters mount via single ring screw-in design. 2½” MS2 meters support three-stud and four-stud ANSI C3 mountings. Dial and pointer customization, including mirrored and multicolor options, available upon request.
