DescriptionThe Desco Analog Surface Resistance Test Kit is a portable battery-powered instrument designed to measure resistance point-to-point (RTT) and surface to ground (RTG). The meter is equipped with an automatic test voltage selector. The test voltage will switch from 10V to 100V should the measured resistance exceed 10E5 ohms.ESD protected area products should be tested:A. Prior to installation to qualify for listing in user’s ESD control plan. Approved ESD materials (see product qualification table at ANSI/ESD S20.20-2007 Table 3 EPA ESD control items)B. During initial installationC. For periodic checks of installed products as part of ANSI/ESD S20.20-2007 Compliance Verification testing per ESD pliance Verification Plan“A Compliance Verification Plan shall be established to ensure the Organization’s fulfillment of the technical requirements of the ESD Control Program Plan. Process monitoring (measurements) shall be conducted in accordance with a Compliance Verification Plan that identifies the technical requirements to be verified, the measurement limits and the frequency at which those verifications shall occur. The Compliance Verification Plan shall document the test methods and equipment used for process monitoring and measurements. If the test methods used by the Organization differ from any of the standards referenced in the document, then there must be a tailoring statement that is documented as part of the ESD Control Program Plan. Compliance verification records shall be established and maintained to provide evidence of conformity to the technical requirements.The test equipment selected shall be capable of making the measurements defined in the Compliance Verification Plan.” (ANSI/ESD S20.20-2007 section 7.3)The Analog Surface Resistance Meter and its accessories are available as the following item numbers:Figure 1.

DescriptionThe Desco Ionization Test Kit allows the 19492 Digital Static Field Meter to be used to measure the offset voltage (balance) and charge decay of ionization equipment. The Test Kit also includes a Charger used to place a ±1000V charge on the 19498 Conductive Plate, making it possible to also measure the discharge times of air ionization equipment per ANSI/ESD SP3.3 Periodic Verification of Air Ionizers. The 19493 Ionization Test Kit includes the 19492 Digital Static Field Meter, providing a highly portable and cost effective means of verifying the performance of a wide variety of ionization equipment.Note: The 19492 Digital Static Field Meter is designed to operate only with the 19493 Ionization Test Kit. It is not compatible with other brands.Although not as accurate, the Desco Ionization Test Kit has been designed to make measurements that correspond to those made by using a charged plate analyzer and ANSI/ESD S3.1. The Ionization Test Kit provides convenience and portability to test per ANSI/ESD SP3.3 Periodic Verification of Air Ionizers or Compliance Verification ESD TR53. We recommend EMIT’s 50555 / 50561 Charged Plate Analyzer if precise measurements are required.The Ionization Test Kit includes a slide-on isolated Conductive Plate, a ±1000 volt Charger and a durable thermoplastic carrying case with custom cut-outs for all of the above components along with the model 19492 Digital Static Field Meter.Charged insulators in the ESD protected area can adversely impact quality, productivity, and reliability.“When any object becomes electrostatically charged, there is an electrostatic field associated with that charge. If an ESDS (ESD sensitive) device is placed in that electrostatic field, a voltage may be induced on the device. If the device is then momentarily grounded, a transfer of charge from the device occurs as a CDM (Charged Device Model) event. If the device is removed from the region of the electrostatic field and grounded again, a second CDM event will occur as charge (of opposite polarity from the first event) is transferred from the device.” (ESD Handbook ESD TR20.20 section 2.7.5 Field Induced Discharges) Compliance verification should include periodic checks with a static field meter to determine if high charging material is present in the ESD protected area. All packaging and other materials that may be electrostatic generative to 2,000 volts must be kept a minimum of 12" from ESD sensitive items at all times. It is proper to rub an item and measure that it can charge.“In order to mitigate field-induced CDM (Charged Device Model) damage, the ESD program shall include a plan for the handling of process-required insulators. If the field exceeds 2,000 volts/inch, steps shall be taken to either:A. Separate the insulator from the ESD-sensitive device by a distance of 30 cm (12 inches); orB. Use ionization or other charge mitigating techniques to neutralize the charge.” (ANSI/ESDS20.20 section 8.3)Other steps that can be taken are to remove the item from the ESD protected area, periodically coat with a topical antistat, or replace with a static control protective version of the item.Packaging1 Digital Static Field Meter1 Conductive Plate1 Charger2 9V Alkaline Batteries1 Data Output Cord1 Carrying Case1 Certificate of CalibrationFigure 1.
