Характеристики

ET-30B multi-function calibrator is a digital AC and DC standard voltage and current generator with LCD display. The whole machine adopts "closed loop" control, with high output stability, which can be used to verify digital and various pointer types. Three-purpose meter and various types of meter heads with DC level 0.1 and AC level 0.2. The voltage output of this instrument is 11 files (0 ~ 1000V); the current output is 11 files (0 ~ 20A); the median resistance is 11 × 2 files (0Ω ~ 20MΩ); the AC frequency is 50Hz, 60Hz, 400Hz (digital synthesis, key selection) The above items and range conversion are converted by internal precision switches. The three windows simultaneously display the actual output value, percentage, and frequency. The output adjustment can be adjusted either "bitwise" or "percent". Using the latest 16-bit A / D conversion chip, the conversion speed and accuracy have been greatly improved; AC / DC uses a true effective value conversion chip to ensure the accuracy of the AC output. A new type of composite high-power amplifier is adopted, which has high output power, high reliability and low distortion. It has the advantages of digital display, wide range, fine division, high precision, good stability and convenient use.
