Tight-tolerance, laboratory-grade decade sub sƟtut ers, for applicaƟons requiring a cost-effecƟve, high-per for mance resistance decade box.
Features:
• Resistance from 1 mΩ to 111 MΩ
• Available in double-power version: HARS-X2
• Wide choice: single through 11 decade units
• High-accuracy: 0.01% (100 ppm)
• Very low zero-resistance: <1 mΩ per decade
• High-performance solid silver-alloy switches
• Low temperature coefficient: 5 ppm/°C
• Non-inducƟve or low-inductance resistors
• Rack mounƟng available
• Special and custom configuraƟons available
Accuracy:
≤1 MΩ decades: ±(0.01% + 2 mΩ)
10 MΩ decades: ±0.03%
after subtraction of zero resistance, at 23°C;
traceable to SI
Zero resistance:
≤1 MΩ decades: <1 mΩ per decade at dc
10 MΩ decade: ≈3 mΩ at dc
Max voltage to case:
2000 V peak
Environmental conditions:
Operating: 10°C to 40°C; <80% RH
Storage: -40°C to 70°C
Switches:
Continuous rotation
11 positions marked "0"-"10"
Multiple solid silver-alloy contacts
Switch capacitance:
