HZ-3500 Process Calibrator Thermal Instrument
Instruction Manual Huazheng Electric Manufacturing (Baoding) Co., Ltd

Overview

The thermal instrument calibrator can not only provide a variety of standard signal sources, but also have an intelligent instrument calibration system. It can excellently measure DC voltage, millivolt voltage, current, resistance, temperature, and frequency signals, and can also provide DC voltage, current, resistance, and frequency signal output, and can calibrate various data collectors, recorders, and multimeters. and other industrial instruments.

• Measure and output DC voltage, millivolt voltage, DC current, two, three, four-wire resistance, frequency and other signals.
• Measure and output 8 kinds of thermocouples (K, E, J, T, N, R, S, B), 4 kinds of thermal resistances (Pt100, Pt10, Cu100, Cu50), and provide cold junction compensation function. Thermal resistance measurement is divided into 3-wire and 4-wire measurement, which provides more convenience for users.
• Six-digit display, using 128X64 dot-matrix graphic liquid crystal display, the display content is rich, clear and practical, its simple operation buttons and screen display  make it easy for you every day, and the large screen with high-brightness backlight allows you to easily read data .
• Because the instrument uses high-precision devices, the accuracy and linearity are very high. In manual calibration, each option of measurement and output is 2  calibration points, no linear correction is required, and cumbersome operations are avoided.
• All measurements and outputs are digitally set for easy operation.
• High-performance zero-impedance terminals and test leads are more reliable to use.
• DC24V output, can be used for loop verification (0-30mA).
• Built-in rechargeable battery.
