   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.

dBc
dBc (decibels relative to the carrier) is the power ratio of a signal to a carrier signal, expressed in decibels. If the dBc figure is positive, then the relative signal strength is greater than the carrier signal strength. If the dBc figure is negative, then the relative signal strength is less than carrier signal strength.

Load Regulation
Load regulation is the capability to maintain a constant voltage (or current) level on the output channel of a power supply despite changes in the supply's load (such as a change in resistance value connected across the supply output).

Power Linearity
When changing the power level and measuring the differences (in dB) between actual and displayed power levels, the power linearity is ± half the span (in dB) between the maximum and the minimum value of all differences.

Settling Time
Settling time of an output device is the time elapsed from the application of an ideal instantaneous step input to the time at which the amplifier output has entered and remained within a specified error band, usually symmetrical about the final value.
