DO30A * multifunctional calibrator

1. Overview
DO30A*The multifunctional calibrator is an intelligent AC and DC standard voltage and current standard source. Three windows simultaneously display output values, percentages, and range values. The range can be subdivided as needed and the corresponding step size can be selected. The amplitude adjustment can be adjusted separately with a button or analog (encoder), or simultaneously with a button and analog, making it very convenient to use. The instrument has the characteristics of digital display, direct error reading, wide range, fine grading, high accuracy, good stability, and easy use. Suitable for verifying, calibrating, and repairing digital multimeters, voltmeters, and ammeters with four and a half digits or less, as well as various pointer multimeters, AC/DC voltmeters, and ammeters with a rating of 0.2 or below; It can also be used as a high stability testing power supply, in conjunction with high-level standard meters, to calibrate 0.1 level ammeters and voltmeters.This instrument can achieve data transmission and printing by connecting to a computer through a USB interface.

2. Main functions

2.1 Six digit LED digital display, with output values displayed in two ways: actual value and percentage.

2.2 Use buttons to adjust the increase or decrease of output values for easy detection of digital instruments. There are two adjustment modes: percentage adjustment based on the range and adjustment based on the corresponding display digit of the button (bit adjustment).

2.3 Simulate the adjustment of output values to facilitate the detection of pointer instruments. Simulate using encoder adjustment.

2.4 It can also be adjusted freely with the analog encoder in percentage adjustment or bit adjustment mode.

The output range of AC and DC voltage is 0-1050V.

2.6 The output range of AC and DC currents is 0-24A.

2.7 There are five AC frequencies available for selection: mains synchronous, 50Hz, 60Hz, 400Hz, 1kHz (with stable crystal oscillation frequency).

2.8 Output overload automatic protection and manual reset.

2.9 AC 50Hz output can choose mains synchronization to reduce the impact of the frequency of the tested meter.

2.10 Clamp ammeter measurement: Equipped with our standard coil, it can measure clamp ammeters from 0 to 1000A with an error of ± 0.3%.

3. Technical performance
