   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.

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.

dBm
dBm (sometimes dBmW) is an abbreviation for the power ratio in decibels (dB) of the measured power referenced to one milliwatt (mW). Zero dBm equals one milliwatt. A 3 dB increase represents roughly doubling the power, a 3 dB decrease, the power is reduced by about one half.

Millimeter-wave
Millimeter-wave is a term that generally refers to frequencies of 26.5 GHz and above. That is where signal wavelengths fall below approximately 10 mm, and thus the terminology changes from centimeters to millimeters.

Power Repeatability
Power Repeatability is the random uncertainty in reproducing the power level after changing and re-setting the power level. The power repeatability is ± half the span (in dB) between the highest and lowest actual power. Note: - The long-term power repeatability can be obtained by taken the power repeatability and power stability into account.

Stability
Stability is the extent to which a specified property, characteristic, or parameter of a substance, device, or apparatus, remains fixed with the passage of time or with varying environmental conditions.
