Huasheng Thermal Power Handbook

When personnel in the self-control industry conduct on-site maintenance and debugging, they particularly need a portable instrument that can quickly detect and diagnose various faults. Such a good instrument can calibrate or simulate pressure transmitters, differential pressure transmitters, vortex flowmeters, thermocouples, and thermal resistors, and can provide power distribution for on-site instruments and quickly query complex thermal manuals Using a 16 bit microcontroller as the CPU, it integrates large-scale digital conversion integrated circuits and large screen LCD display technology. It has output, measurement, manual, and 24VDC power distribution functions, and all four functions can work simultaneously. It is also equipped with a large capacity rechargeable battery for power supply, making it easy to carry and suitable for on-site maintenance and debugging by personnel in the thermal instrument industry. The combination of structure and function gives it the following usage characteristics:

&. Compact, easy to carry and hold.

&. Durable and reliable, the support frame and hook holes on the back are suitable for on-site use.

&. Large display screen, capable of displaying measurement, output, and thermal manual data simultaneously.

&. It can measure voltage, current, thermocouple, frequency, platinum resistance, copper resistance, and ordinary resistance.

&. It can output signals such as voltage, current, millivolts, frequency, etc.

&. The 24V DC distribution output provides loop power for the transmitter.

&. The thermal manual enables quick cross checking of resistance values and temperature values, millivolt values and temperature values, and enables quick querying of saturated steam pressure and density, temperature and density.
