• Tests path to ground of operator to determine if grounding devices working properly
• Simultaneous testing of wrist strap and footwear in less than 3 seconds
• Wrist strap limits - 750 kilohms and 10 megohms
• Footwear limits 750 kilohms and 35 megohms
• Compatible with single-wire and dual-wire straps

The SCS Dual Combination Tester verifies the functionality of personnel grounding devices (wrist straps, foot grounders, ESD shoes, smocks). Three independent tests are performed simultaneously on the wrist strap and each foot. Green lights indicate a pass condition. Red and yellow lights plus an audible alarm indicate when the wrist strap and/or footwear (left or right) have failed. DIP switches may be accessed for test limit preferences. Access control to an ESD Protected Area can be further enforced by using the relay terminal on the Dual Combination Tester and connecting it to an electronic door lock or turnstile to grant access only to those who have passed their personal grounding device tests. The Dual Combination Tester is calibrated to NIST standards and includes a certificate.

• Tests operator’s path-to-ground - Wrist Strap Limits 750 kilohms to 10 megohms, Footwear Limits 750 kilohms to 35 megohms; Determines that operator’s personnel grounding devices (wrist straps, foot grounders, ESD shoes, smock) are functioning correctly
• Compatible with single-wire and dual-wire wrist straps
• Simultaneous testing of wrist strap and footwear in the less than 3 seconds - Reduces time spent testing personal grounding devices used in ESD Control Plans
• Solid-State test switch – No moving parts, maintains accuracy of tests and extends the lifetime of the tester
• Split foot plate for testing foot grounders - Tests both foot grounders independently at the same time
• 30 Volt test signal - Provides accurate tests that are not humidity dependent
• Relay for use with automatic doors or other locking systems - Control access to ESD Protected Areas
• NIST calibrated with certificate
• Made in the USA

Default test limits listed. Additional test settings are noted in the user guide.

The Dual Combination Tester will also test a Groundable Static Control Garment System. The Groundable Static Control Garment System must have an RTG of < 3.5 x 107ohms to meet the required limit of ANSI/ESD S20.20-2007 tested per ANSI/ESD STM2.1 and ESD TR53.
