Measure Tech's AC current shunt (model# EL-9800) has expanded AC current measurements far beyond existing levels. For the first time, the new primary standard allows current calibration to be certified by the National Institute of Science and Technology (NIST) to 100 amp and 100 kHz. This product has been tested by NIST and approved by the U.S. Air Force to be used in all of the Air Forces precision measurement laboratories.
EL-9800 shunt set includes the following shunts for different ranges of current.
Model Number | Current Range (Amperes) | Nominal Resistance (Mili-Ohms) | Frequency Range |
EL-9810 | 10-30 | 23 | DC-100KHZ |
EL-9830 | 30-50 | 8 | DC-100KHZ |
EL-9850 | 50-80 | 5 | DC-100KHZ |
EL-9880 | 80-100 | 3 | DC-100KHZ |
Over a 10 minute interval, the output voltage of each unit will remain stable within the following specifications.
Frequency Range | Maximum Variability of Output Voltage (Percent) |
DC | +/- 0.001% |
10Hz to 1KHz | +/- 0.002% |
1KHz to 10KHz | +/- 0.004% |
10KHz to 20KHz | +/- 0.02% |
20KHz to 100KHz | +/- 0.2% |
