Product Description
ET-30D multi-function calibrator is a large-screen LCD display of digital AC and DC standard voltage and current generators. The whole machine adopts "closed loop" control with high output stability, which can be used to verify digital and various Pointer type multimeter and various types of meter heads with DC 0.1 level and AC 0.2 level. The voltage output of this instrument is 11 gears (0 ~ 1000V); the current output is 11 gears (0 ~ 20A); the median resistance is 11 × 2 gears (10Ω ~ 20MΩ); there are two types of AC frequency: fixed frequency: 50Hz, 60Hz, 400Hz, 1kHz (digital synthesis, key selection), frequency modulation: 50Hz-1000Hz continuously adjustable. The above items and range conversion are converted by internal precision switches. The LCD window simultaneously displays the output actual value, percentage value, quantity limit, and error. The limit value of the meter to be checked can be selected, and the step size can be selected according to the scale of the meter to be checked. The output adjustment can be adjusted by external control encoder or digital adjustment by panel keys. The adjustment by panel keys can be adjusted by "bit" 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 powerful output power, high reliability and low distortion. Automatic protection of voltage short circuit and current open circuit! It has the advantages of digital display, direct error reading, wide range, fine division, high precision, good linearity, high stability, easy to use and so on!1. Main technical indicators:1.1 Stability: AC <0.02% / 5min of full scale, DC <0.005% / 5min of full scale. 8-hour stability: 30% accuracy.1.2 Resolution: 20ppm (0.002%).1.3 AC distortion: <0.5%, 20A <2%.1.4 DC ripple factor: <0.1%.1.5 Output frequency accuracy <0.1%.1.6 Dimensions: 460 × 460 × 130 (mm). Weight: about 18KgRange and accuracy of output voltage, current and median resistance:Output item | Output range | Rated output | Maximum output | Accuracy |
