AEMC 3640 3-Point Digital Ground Resistance Tester

The AEMC 3640 3-Point Ground Resistance Tester performs ground resistance measurement. This direct reading tester measures from 10 m-ohm to 1999 ohm, and is auto-ranging, so it automatically seeks out the optimum measurement range. The Model 3640 is easy to use - simply connect the leads, press to measure, and read. The large LCD (nearly 3/4" high) also indicates low battery status, overrange, and lead reversals. The Model 3640 comes with 3 color coded terminals to aid in easy hookup. Three LED indicators on the front panel continuously warn the user of measurement problems to ensure accurate and reliable tests. Specifications. Types of Measurements: 2- and 3-Point. Display: Digital. Soil Resistivity Test: No. Measurement Ranges: 20 ohm, 200 ohm, 2000 ohm. Resolution: 10 m-ohm, 100 m-ohm, 1 ohm. Test Current: 10 mA, 1 mA, 0.1 mA. Open Voltage: 42V peak. Operating Frequency: 128Hz square wave. Accuracy: 3% of Reading ± 3cts; 5% of Reading ± 3cts. Interference: rejects high levels of interference voltage (DC, 50 to 60Hz, harmonics).

*This is a Web introductory price for one calibration of the AEMC 3640. 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
