DESCO 19787 Digital Surface Resistance Meter Kit

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.

*This is a Web introductory price for one calibration of the DESCO 19787. Price does not in most cases include measurement performance data. Pricing does include NIST traceable calibration and issue of a calibration certificate and calibration label. Pricing may vary slightly due to volume and location of laboratory supporting calibration. Volume pricing may apply. On-site fees may apply depending on logistics, location and volume of work to be completed during the visit.

Clipping
Clipping is the limiting of a signal so that it never exceeds some threshold.

Line Regulation
Line regulation is the capability to maintain a constant output voltage level on the output channel of a power supply despite changes to the input voltage level.

Peak Envelope Power
Peak envelope power is the maximum value of the envelope power. Envelope power is measured by making the averaging time much less than 1/fm where fm is the maximum frequency component of the modulation waveform. The averaging time is therefore limited on both ends: (1) it must be small compared to the period of the highest modulation frequency, and (2) it must be large enough to be many RF cycles long.

RMS
RMS or root mean square is a statistical measure of the magnitude of a varying quantity
