An economical set of precision high resistance standards designed for testing megohmmeters or other instruments; 9 or 10 values up to 10 TΩ with special Kel-F isolaton.
Features:
• Set of nine resistors - 1 kΩ, 10 kΩ, 100 kΩ,
1 MΩ, 10 MΩ, 100 MΩ, 1 GΩ, 10 GΩ,
100 GΩ, (1 TΩ and 10 TΩ optonal), open
circuit
• Nonstandard value sets up to 10 TΩ
• High-accuracy - up to 20 ppm
• Maximum voltage: 5,000 V or 10,000 V
• Excellent TC - up to 5 ppm/°C
• Excellent stability - up to 10 ppm/year
• Both Ground and Guard terminals are
brought out to minimize leakage effects
• Two styles available
| Nominal value | Max voltage | to accuracy Adjustment | Temperature coeffcient | coeffcient Voltage (±ppm/V) | Stability |
| 1 kΩ | 50 V | 20 ppm | 3 ppm/°C | - | 10 ppm/year |
| 10 kΩ | 150 V | 20 ppm | 3 ppm/°C | - | 10 ppm/year |
| 100 kΩ | 500 V | 20 ppm | 3 ppm/°C | - | 10 ppm/year |
| 1 MΩ | 1,250 V | 20 ppm | 5 ppm/°C | <1 | 15 ppm/year |
| 10 MΩ | 5,000 V | 50 ppm | 25 ppm/°C | <1 | 20 ppm/year |
| 100 MΩ | 5,000 V or 10,000 V | 100 ppm | 25 ppm/°C | 1 | 100 ppm/year |
| 1 GΩ | 5,000 V or 10,000 V | 0.50% | 25 ppm/°C | 1 | 500 ppm/year |
| 10 GΩ | 5,000 V or 10,000 V | 0.50% | 50 ppm/°C | 2 | 500 ppm/year |
| 100 GΩ | 5,000 V or 10,000 V | 1% | 50 ppm/°C | 5 | 500 ppm/year |
| 1 TΩ | 5,000 V or 10,000 V | 2%* | 100 ppm/°C | <20 (10 ppm typical) | 500 ppm/year |
| 10 TΩ | 5,000 V or 10,000 V | 5%* | 300 ppm/°C | <20 (10 ppm typical) |
