5. Characteristic
☆ Analog Resistance Output |
• The four-wire wiring method can effectively eliminate the measurement error caused by the resistance of the test wire, and the measurement accuracy is higher; • Compared with the physical resistance box, the analog resistor has the following advantages: ① The resistance value is continuously adjustable, the adjustment fineness and the sensitivity are better; ② There is no influence of switch error, residual resistance error, contact resistance error, etc., and the measurement data is accurate and reliable; ③ The physical resistor will cause the resistance value to change when overloaded, and even cause the resistor to be damaged in severe cases. This device has current overload capacity and impact resistance, and has been fully tested for electrostatic protection and electromagnetic compatibility, with good protection performance and high reliability. • The device has a self-calibration function to ensure that the value is accurate and stable for a long time. |
☆ Wide Range Current Measurement |
• Direct current measurement: A pair of quick-connect terminals can be used to directly measure a wide range of AC and DC currents from 10 mA to 60 A, solving the top problem of automatic range switching for ultra-wide range AC and DC currents. • Current conversion measurement: The instrument is equipped with a sensor-specific measurement interface, which can simultaneously power the sensor and measure its secondary signal. It can be connected to a precision current sensor (such as TH0540-T) to expand the current range to 100A, 200A, 500A or even larger. By setting the ratio of the current sensor on the instrument, the size of the primary current of the measured sensor can be directly displayed. • Solution advantages: This flexible combination of direct measurement and conversion measurement can effectively reduce the size and weight of the instrument while maintaining the wide range and large current measurement capabilities of the instrument, making it very convenient to carry out current measurement work; especially for on-site calibration, users can carry the instrument body or choose a suitable sensor according to the calibration requirements. |
☆ AC and DC Integrated Measurements |
• The instrument supports DC or AC (optional) measurement mode, and the AC frequency range is: 45 Hz ~ 65 Hz. • When measuring current, the distortion and ripple can be measured simultaneously. The maximum measurement bandwidth of DC ripple is 1 kHz, and AC supports the measurement of the 2nd to 16th harmonics (optional). • Solution advantages: The rich measurement modes can not only measure the errors of various DC current sources, AC current sources, DC low-resistance measuring instruments, and AC low-resistance measuring instruments, but also facilitate users to effectively evaluate the signal quality of the output power of DC or AC sources, which reduces the initial investment and effectively improves the test efficiency. |
