Overview
DO30B-2/DO30 IIB/HG30-3a multifunctional calibrator
Product Details
DO30B-2/DO30 IIB/HG30-3a multifunctional calibrator
1. Overview
The DO30B-2 multifunctional calibrator is an intelligent AC and DC standard voltage and current source. It has the characteristics of digital display, wide range, fine grading, high accuracy, good stability, and easy use. Suitable for verifying and calibrating digital and pointer type multimeters below level 0.2, as well as AC and DC voltage and current meters; It can also be used as a high stability testing power supply, in conjunction with high-level standard meters, to calibrate current and voltage meters above 0.1. Equipped with standard coils, it can detect 0-1000A AC, DC digital and pointer clamp gauges.
2. Main functions
2.1 51/2-digit LED digital display, with three windows simultaneously displaying the output actual value, percentage, and frequency.2.2 Output adjustment can be achieved through "position adjustment", "percentage adjustment" (light touch key, good tactile feel, long lifespan), and analog adjustment
2.3 The external control regulator can control the increase or decrease of output quantity off the machine (without wear on the encoder).2.4 The output range of AC and DC voltage is 0-1050V, divided into 11 ranges.
The output range of 2.5 AC and DC currents is 0-22A, divided into 11 ranges.2.6 There are three types of communication frequencies: 50Hz, 60Hz, and 400Hz. (Digital synthesis, key selection)
2.7 Output overload automatic protection, manual reset (equipped with on/off keys for safer use). 3. Technical performance
3.1 The range and accuracy of output voltage, current, and median resistance should comply with the parameters in the table below (22 ℃± 2 ℃). The basic range of this instrument is 1V. When 50Hz is unstable, please choose 60Hz
3.2 Stability: AC<0.02% of basic full scale/5 minutes
DC<0.01% of basic full scale/5 minutes
3.3 Communication distortion:<0.5%3.4 DC wave coefficient:<0.5% (when the output DC voltage is greater than 1V)
3.5 Output frequency accuracy: 50Hz, 60Hz, 400Hz<0.5%3.6 Power consumption: Power consumption<180VA.
3.7 Power supply: AC power supply voltage 220V ± 10%, frequency 50Hz ± 1Hz3.8 Working environment: ambient temperature 5 ℃~35 ℃, relative humidity<80%
