AEMC 3731 Clamp-On Ground Resistance Tester

The AEMC 3731 Clamp-on Ground Resistance Tester measures ground rod and small grid resistance through any season, without the use of auxiliary ground rods. Check Resistance on Single and Multiple Rods or Grids. Clamp-on Ground Resistance Testers are used in multi-grounded systems without disconnecting the ground under test. The AEMC 3731 simply clamps around the ground conductor or rod and measures the resistance to ground. By performing measurements on intact ground systems, the user also verifies the quality of the grounding connections and bonds. Resistance and continuity of grounding loops around pads and buildings may also be measured. The Model 3731 also provides alarm and memory functions. Specifications. Ground Resistance Measurement Range: Autoranging 0.01 to 1200 ohm. Ground Resistance Resolution: 0.01 ohm (0.1 to 1.0 ohm), 0.1 ohm (1.0 to 50.0 ohm), 0.5 ohm (50.0 to 100.0 ohm), 1 ohm (100 to 200 ohm), 5 ohm (200 to 400 ohm), 10 ohm (400 to 600 ohm), 50 ohm (600 to 1200 ohm). Ground Resistance Accuracy: ± (2% + 0.02 ohm) (0.1 to 1.0 ohm), ± (1.5% + 0.1 ohm) (1.0 to 50.0 ohm), ± (2.0% + 0.5 ohm) (50.0 to 100.0 ohm), ± (3.0% + 1 ohm) (100 to 200 ohm), ± (6.0% + 5 ohm)(200 to 400 ohm), ± (10% + 10 ohm) (400 to 600 ohm), 25% of Reading ±50 ohm (600 to 1200 ohm). Resistance Measurement Frequency: 2403 Hz. Ground or Leakage Current: Autoranging 1 mA to 30.00 Arms. Current Measurement Frequency: 47 to 800 Hz. Current Overload: OL displayed above 29.99 Arms.

*This is a Web introductory price for one calibration of the AEMC 3731. 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
