One,    Usage, Features:

XF30DQ-GType Multi-functional Calibration Instrument(Hereinafter referred to as the Calibrator) is a five-and-a-half-digitLCDLCD digital display output values, and can simultaneously display the error, error correction value, output percentage, full scale value of the measured instrument, step value, frequency, and other parameters of AC and DC voltage, current calibration sources. Equipped with22Standard resistor set, convenient for calibrating multimeter resistance range. AvailableRS232Interface implements automatic data processing functionality.

XF30DQ-GUtilizing advanced amplitude stabilization, power amplification, and protection technologies, it ensures excellent stability, high precision, wide measurement range, fine gradation, and safety reliability. The amplitude adjustment combines digital key control and encoder adjustment, allowing for flexible control and rapid response, catering to both fixed-value output and continuous adjustment needs, making operation more convenient and efficient. Suitable for calibration and verification of 4.5-digit digital multimeters and various other applications.0.2Current and voltage meter heads below a certain level, along with corresponding accuracy grades, multi-meters. Also usable as a high-stability test power source, in conjunction with high-grade standard meters, for calibration.0.2Grade A and above current and voltage meters. Widely used in quality inspection, metrology, and instrument maintenance in industrial and mining enterprises, scientific research institutions, railways, and power companies.

One,    Primary Functions:

2.1 5Piece halfLCDDigital display of output volume, simultaneous display of gear, range, and measured value error of the inspected itemr_AAnd reference errorr_mError correction values, output percentage, gauge fullness value, frequency, step value; simultaneously display output in both actual values and percentages, instantly read the error of the inspected gauge, saving time and effort.

2.2 The output quantity adjustment is controlled using a regulator keyboard. The regulator features both keyboard and encoder configurations, with the cursor initially positioned at the next digit. Pressing the arrow keys allows movement to the bottom of any digit except the first. The encoder adjusts the value based on the cursor's position. The keyboard controls are divided into100 %/N、10%/N、1%/N、0. 1%/N、0.01%/N（NPlease provide the Chinese content that needs to be translated into American English.3、4、5、6、10、15）。

2.3AC and DC voltage output range:0～ 250mV～1V～2.5V～5V～10V～25V～50V～100V～250V～500V～1000V,Peak voltage output1100V。

2.4 AC & DC Current Output Range:0～100uA～500uA～2.5mA～10mA～25mA～100mA～250mA～1A～2.5A～10A～50A,Peak Current Output55A。

2.5 In addition to the range specified on the instrument, the range can also be expanded by pressing the full-scale key on the regulator, such as...250 mVFile can be expanded to75 mV、100 mV、125 mV、150 mV、200 mV、250mVSpecific extended range is shown in the table.2Completely meets the requirements for various range detection of the inspected instruments.

2.6 To meet the diverse requirements of various inspection tables, the calibrator is equipped with two main output terminals, namely the common terminal (black contact) and the AC/DC output terminal (red contact); the terminal between the black and red contacts is for AC/DC voltage and current output; auxiliary output sockets: two (black contacts are connected to the green wire separately)-Yellow plug for calibration of AC high resistance meters.

2.7Four selectable output frequencies: availableLEDDisplay40Hz-1200HzContinuous adjustable, using digital technology to ensure accuracy and stability of frequency.

2.8 Overload protection is automatic, reset manually. (When the meter is overloaded or the confirm key is pressed without the computer connected, the screen displays “)Send to PCAt that time, press the reset button to restore the instrument to normal operation.

2.9 Resistance Output Selection

Select different positions based on the required resistance value. From the black jack and green hole “×1Socket can output10Ω～24kΩ common11A variety of standard resistors, from black jacks and yellow "×"1000Socket can output10kΩ～24MΩ Total11Standard resistors.

2.10 Clamp meter measurement: Supplied with our factoryHG1000AStandard coil, measurable0～1000ACurrent, conversion error ±0.8%Turn the clamp meter on the lower right corner of the front panel./Actual value selection switch, placed on one side of the clamp meter, enables the display of the clamp meter's test values.

2.11In addition to the functions inherent in the instrument itself, it can also be used for:RS232Connect interface to computer, use our company's dedicated measurement software for data processing, and print test data online.
