Resistance decade box 10 Ω to 2 GΩ for the calibration of ESD testers - Iteco 9264981

Test stations judge not only the lower but also the upper resistance limit of personnel grounding. Where that limit sits in the gigaohm region, a decade box ending at 110 MΩ can no longer reach it. Version 9264.981 goes up to 2 GΩ and thus covers the complete assessment range of current testers with a tolerance of ±1 %.

What the large version offers

• Upper limit of 2 GΩ instead of 110 MΩ, so the upper switching thresholds of personnel and footwear testing are reached
• Resolution of 100 Ω, matched to the extended span of the decade box
• Resistor tolerance of ±1 % across the whole range, which keeps the tester and not the reference the source of any deviation
• Rated 1 W up to 4 MΩ and 0.5 W from 10 MΩ to 40 MΩ, operating voltage up to 250 V AC
• Same compact housing as the smaller model with 147 x 117 x 55 mm and 320 g, so handling in the field is unchanged
• Cables, adapters and the detailed manual on the calibration procedures of IEC 61340-5-1 are included

Applications

• Calibration of test stations whose upper pass limit lies above 110 MΩ
• Verification of Wristlab PRO installations with an extended measuring span
• Central test equipment control at sites running different tester generations
• Investigating borderline cases where people repeatedly fail by a small margin
• Service providers and auditors who want to cover several customer installations with one reference

Compatibility and scope of supply

The decade box is intended for Wristlab-II, Test Station EVO, Wristlab PRO and other testers working to IEC 61340-5-1. Cables and measuring adapters are included. If only the range up to 110 MΩ is needed, version 9264.980 is the more economical choice. Recalibration of this decade box is ordered as separate item 9264.982 with a traceable ISO9000 certificate.
