   AEMC 3730 (1221.02)   Description / Specification:   Spec Sheet 
AEMC 3730 Clamp-On Ground Resistance Tester

The AEMC 3730 Ground Resistance Tester simply clamps around the ground conductor or rod and measure the resistance to ground. The probe’s high sensitivity enables measurement of leakage current flowing to ground or circulating in ground loops down to 1 mA and neutral currents to 30 Arms. This feature provides additional information which is becoming vital as distribution ground networks carry higher levels of noise and harmonics which affect power quality. The Model 3730 offers an alarm function and a memory (logging) function. In the alarm mode, the probe will audibly and visually indicate if the reading is beyond an input set point. Specifications. Ground Resistance Measurement Range: Autoranging 1.0 to 1200 ohm. Ground Resistance Resolution: 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: ± (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). Resistance Measurement Frequency: 1.689 kHz. Ground or Leakage Current: Autoranging 1 mA to 30.00 Arms. Current Measurement Frequency: 47 to 800 Hz. Current Overload: OL displayed above 30 Arms.

*This is a Web introductory price for one calibration of the AEMC 3730. 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.

Channel Bandwidth
Channel Bandwidth is the bandwidth over which power is measured. This is usually the bandwidth in which almost all of the power of a signal is contained.

Jitter
Jitter in technical terms is the deviation in or displacement of some aspect of the pulses in a high-frequency digital signal. Jitter is the time variation of a periodic signal in electronics and telecommunications, often in relation to a reference clock source. Jitter may be observed in characteristics such as the frequency of successive pulses, the signal amplitude, or phase of periodic signals. Jitter is a significant, and usually undesired, factor in the design of almost all communications links (e.g., USB, PCI-e, SATA, OC-48). In clock recovery applications it is called timing jitter.

Overshoot
Overshoot is the distortion that follows a major transition; the difference between the peak power point and the pulse-top amplitude computed as a percentage of the pulse-top amplitude.

Rise Time
Rise time refers to the time required for a signal to change from a specified low value to a specified high value, usually 10 and 90 percent of pulse-top amplitude (vertical display is linear power).
