620BH
620BH
The AMPTEC 620BH Igniter Circuit Tester is a portable digital ohmmeter designed for ultra-safe resistance testing on explosive devices. It is approved by the USAF Non-nuclear Munitions Safety Board and features a fail-safe current limiting resistor network to ensure test currents do not exceed 8 mA, even in the event of a component failure. The device is part of the 620 Series product line, offering high-accuracy resistance measurements from 2 Ω to 20 MΩ.
- Range & Current Levels: Ranges from 2 Ω to 20 MΩ with nominal currents from 5 mA to 5 nA and a failsafe current of 8 mA across all ranges.
- Resolution & Accuracy: Resolution varies from 100 uΩ to 1 KΩ, with accuracy ranging from ±0.02% to ±2% depending on the range.
- General Specifications: Features a 4 ½ digit LED display, dimensions of 9.75” x 10” x 3.25”, and a weight of 3.5 lbs. Operating temperature is 0º to 50º C, with storage limits from -20º to 70º C.
- Power Specifications: Powered by four 5000 mAh NICAD batteries with a charge time of ~8 hours and a life of 1000 cycles or 3 years.
- OP-232 RS232C Interface: Allows connection to a computer via a DE-9 connector.
- OP-247 Optically Isolated Power: Enables AC power operation with a 24 VDC output.
- OP-519 Rack Mount: Available for single or dual units, allowing for rack mounting.
The 620BH package includes the igniter tester, OP-300 leads, a battery charger, and a N.I.S.T. calibration certificate. Additional accessories such as transit cases, test lead storage pouches, and various clip leads are available.
Catalog excerpts
The 620BH Igniter Circuit Tester & Fail-Safe Ohmmeter The gold standard in ultra-safe resistance testing. The 620BH Igniter Tester is a portable digital ohmmeter specifically designed for ultrasafe resistance testing on explosive devices. Approved by the USAF Non-nuclear Munitions Safety Board and compatible with our RS232C Interface (OP-232), this product is the safest and easiest to use in its field. The AMPTEC 620BH offers fail-safe current limiting resistor network circuitry to ensure that instrument test currents cannot exceed 8 mA. In the unlikely event of a component failure, the output current limiting network would still be in effect. If the 620BH had an electrical fault, it offers the life-saving advantage of failing safely. The 620BH is part of a lineage of intrinsically safe igniter circuit testers in the 620 Series product line, enabling you to take high-accuracy resistance measurements across virtually any range from 2 Ω to 20 MΩ. Every AMPTEC product is proudly made from start to finish in the USA and comes with a one-year warranty, plus an N.I.S.T calibration certificate with data at no extra cost
