The Desco 19787 Digital Surface Resistance Meter Kit is an instrument designed to measure resistance point-to-point (Rtt) or surface to ground (Rtg) in accordance with ESD Association Standard ANSI/ESD S4.1. Its test funcitions include; Resistance measurement accuracy of ±10% (±20% for resistance values 1 x 10^11 and greater). Resistance range of <1 x 10^3 ohms to >1 x 10^12 ohms. Under load voltages of 10 and 100 volts ±5%. Electrification period of approximately 15 seconds. The Digital Surface Resistance Meter also measures ambient temperature and relative humidity. Specifications. Resistance Ranges: 1 x 10^3 - 1 x 10^12 ohms @ 10 Volts, complies with ANSI/ESD S4.1, 1 x 10^6 - 1 x 10^12 ohms @ 100 Volts, complies with ANSI/ESD S4.1. Accuracy: Resistance measurements within ±10% (±20% for resistance values 1 x 10^11 and greater), complies with ANSI/ESD-S4.1. Under load voltages of 10 Volts ± 5% and 100 Volts ± 5% exceed.
