   AEMC 4620 (2130.43)   Description / Specification:   Spec Sheet 
AEMC 4620 4-Point Ground Resistance Tester

The AEMC 4620 4-Point Ground Resistance Tester performs ground resistance and soil resistivity tests. This direct reading testers measures from 0 to 2000 ohm, and is auto-ranging, so it automatically seeks outs the optimum measurement range. The Model 4620 is rugged, easy-to-use and is ideal for maintenance crews performing numerous tests. It exceeds mechanical and safety specifications for shock, vibration and drop tests called out in IEC standards. It is designed to reject high levels of interference, so it can be used under difficult conditions such as high stray currents that normally affect accuracy. Applications; Three-Point measurements of resistance to ground of ground rods and grids. Four-Point tests or soil resistivity measurements. Touch potential measurements, an alternative to 3-Point tests in evaluating electrical safety. Specifications. Measurement Ranges: Auto-ranging 0 to 2000 ohm. Resistance Resolution: 10 m-ohm (20 ohm), 100 m-ohm (200 ohm), 1 ohm (2000 ohm). Resistance Accuracy: 2% of Reading ± 1ct (20, 200 ohm), 5% of Reading ± 3cts (2000 ohm). Operating Frequency: 128 Hz square wave. Response Time: Approximately four to eight seconds for a stabilized measurement. Withstanding Voltage: 250 Vac or 100 Vdc.

*This is a Web introductory price for one calibration of the AEMC 4620. 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.

Average Power
Average power means that the energy transfer rate is to be averaged over many periods of the lowest frequency involved. For a CW signal, the lowest frequency and highest frequency are the same, so average power and power are the same. For an amplitude modulated wave, the power must be averaged over many periods of the modulation component of the signal as well.

Dynamic range
Dynamic range the ratio of a specified maximum level of a parameter, such as power, current, voltage or frequency, to the minimum detectable value of that parameter.

Modulation
Modulation is the process by which the characteristic of one wave (the carrier) is modified by another.

Repeatability
Repeatability is the variation in a number of repeated measured quantities when measurement conditions are changed and restored. The value corresponds to half the spread between the minimum and maximum value measured.
