DO3051 DC signal source

1. Overview

The DO3051 thermal instrument calibrator is a new generation of intelligent process calibrator, with a mobile menu operation mode and powerful task management functions, meeting the requirements for calibrating temperature, pressure and other process instruments in industrial sites and laboratories. It has the advantages of beautiful appearance, durability, simple operation, clear and delicate display, and is an ideal tool for calibrating, maintaining, and repairing thermal instruments.

2. Main features

2.1. Measurement and output are completely isolated, do not interfere with each other, and can be performed simultaneously;

2.2. It can measure voltage, current, resistance, frequency, pulse, switch (on/off), and can also use thermal resistors or thermocouples to measure temperature;

2.3. It can output signals such as voltage, current, resistance, frequency, pulse, etc;

2.4. It can simulate the measurement and output of 13 types of thermocouples (S, R, B, K, N, E, J, T, C, D, G, L, U) and 9 types of thermal resistors (Pt1000, Pt500, Pt100, Pt10, Cu100, Cu50, Cu10, Ni120, Ni100), and provide cold end compensation (manual or automatic optional) when simulating thermocouple measurement and output;

2.5. Provide a DC24V power supply that is isolated from measurement and output;

2.6. Support step or programming output methods;

2.7. Advanced automatic cold end compensation technology: embedded cold end insulation module, quickly tracks temperature changes;

2.8. High resolution TFT display screen, Chinese language display, good human-computer interaction interface;

2.9. RS232 interface and open communication protocol, facilitating remote networking for users;

2.10. Support online firmware upgrade;

2.11. Small size and light weight.

2.12 RS232 interface: standard RS232-DB9 socket;
