SFJL-HG1000 electric welding machine field calibrator

SFJL-HG1000 electric welding machine field calibrator (hereinafter referred to as the calibrator) is a calibration equipment designed for verifying the current and voltage meters used in various electric welding machines. Generally, welding machines work in a high current state, and the disassembly and assembly of voltage or current meters are complicated. The accuracy of the welding machine indicator directly affects the welding quality, so the calibration of voltmeters and ammeters is very important. This calibrator designed by our company for electric welding machines can measure a maximum AC and DC current of 1,000 amps and an AC and DC voltage of 400 volts.

I. Overview
SFJL-HG1000 electric welding machine field calibrator (hereinafter referred to as the calibrator) is a calibration equipment designed for verifying the current and voltage meters used in various electric welding machines. Generally, welding machines work in a high current state, and the disassembly and assembly of voltage or current meters are complicated. The accuracy of the welding machine indicator directly affects the welding quality, so the calibration of voltmeters and ammeters is very important. This calibrator designed by our company for electric welding machines can measure a maximum AC and DC current of 1,000 amps and an AC and DC voltage of 400 volts. There is no need to disassemble and assemble the electric welding machine instrument. It can be inspected directly on site. The accuracy and stability are very good. High, very safe and convenient to use, it is an ideal calibration equipment for electric welding machines.

2. Technical characteristics
2.1 This calibrator is a six-and-a-half-digit display, highly stable, safe and reliable on-site measurement instrument. It adopts LCD color LCD digital display and can display AC and DC current, voltage, gear, output value, etc. on the same screen.
2.2 This calibrator uses advanced circuits and high-precision integrated circuit chips dedicated to instrumentation to ensure the measurement accuracy and reliability of the calibrator.
2.3 The measuring range of this calibrator is wide. Especially when large current is input, the instrument will generate heat, so the material selection is very important. Our company uses samplers imported from abroad. When the current is large, the thermal stability of this instrument is very good. .
2.4 This calibrator adopts a variety of software and hardware anti-interference measures and digital compensation technology to ensure that the instrument is not affected by harsh environments when used on site.
2.5 This calibrator can perform online on-site calibration of voltmeters or ammeters on welding machines below level 0.2. It is lightweight and easy to carry.
