Resistance decade box 10 Ω to 110 MΩ for the calibration of ESD testers - Iteco 9264980

Anyone running wrist strap and footwear testers to IEC 61340-5-1 has to verify their switching thresholds at regular intervals. The resistance decade box 9264.980 applies defined resistances from 10 Ω to 110 MΩ with a tolerance of ±1 % to the test input and shows whether a tester still decides correctly.

Benefits for test equipment control

• Resolution of 10 Ω across the whole range, so the lower thresholds of personnel testing can be approached precisely
• ±1 % resistor tolerance, considerably tighter than the pass limits of the test stations themselves
• Rated 1 W up to 4 MΩ and 0.5 W from 10 MΩ to 40 MΩ, matched to the test voltages of the testers
• Operating voltage up to 250 V AC, so instruments with higher test voltage can be connected as well
• Compact 320 g in a 147 x 117 x 55 mm housing, fits into any tool or test equipment case
• Cables and adapters are included, together with a detailed manual on the calibration procedures of IEC 61340-5-1

Applications

• Annual or half-yearly in-house verification of test stations
• Incoming inspection of newly purchased testers before release for the EPA
• Troubleshooting when a test station rejects or passes an unusual number of people
• Evidence for auditors that the pass limits of the testers are being checked
• Training of ESD coordinators on defined resistance values

Compatibility and scope of supply

The decade box is built for calibrating the ESD test stations Wristlab-II, Test Station EVO and Wristlab PRO as well as other testers working to IEC 61340-5-1. Cables and measuring adapters are included. If the range is not sufficient because values in the gigaohm region are required, version 9264.981 covers up to 2 GΩ. Recalibration of the decade box itself is available as separate item 9264.982 with a traceable ISO9000 certificate.

Standards and origin

The supplied manual describes the calibration procedures of IEC 61340-5-1. Manufactured by Iteco Trading in Italy.
