- Page 2 GENERAL The Model 818 Resistance Measuring Kit shown in Figure 1 is a cost Effective system for measuring the resistance characteristics of material, flooring, work surfaces, seating, garments, etc. in accordance with current ESD Association, DOD and internal corporate standards.
- Page 3 Figure 2: Model 880 Autoranging Resistance Indicator Accuracy is ±10% of the mean value, with changeover points of ½ decade on a logarithmic scale. Measurements in the Conductive range (<5x10 Ohms) are made at 10 Volts. All remaining measurements are made at 100 Volts. The measurement electrodes, shown in Figure 3, consist of chrome-plated parallel bars 2.5”...

For locations having 230VAC mains the Verifier is not included (Model 818-2) Other measurements, such as volume resistance, seating resistance per ESD...
- Page 5 OPERATION Surface Resistance of Material The Model 880 is designed to measure samples having a flat surface at least 2.5”x1.75”. The sample being tested should be placed on an insulated surface (>10 Ohms) to avoid parallel measurement paths, especially if the material has any bulk resistance.
- Page 6 With extensive use the surface can become uneven resulting in measurements that are higher. The probes should be returned to ETS for periodic recalibration, or if the conductive rubber is damaged or shows excessive wear.
- Page 7 ETS must be notified before any equipment is returned for repair. ETS will issue an RMA (Return Material Authorization) number for return of equipment. Equipment should be shipped prepaid and insured in the original packaging. If...
