High Precision Multifunction Process Calibrator
ADPC-800 high-precision multi-function process calibrator is a high-precision, hand-held process signal measurement/output instrument, which can simultaneously measure and output voltage, current, resistance, thermocouple, thermal resistance, frequency, pulse, switch value, etc. Industrial process signal; built-in HART function, can completely replace the HART Communicator.
The product can replace the measurement and calibration instruments such as current signal source, voltage signal source, resistance box, electronicADPC-800 potentiometer, frequency meter, HART hand communicator, etc. It is mainly used in industrial field signal calibration and fault diagnosis; it is also suitable for signal measurement and calibration in chemical industry, military industry and various research institutes and laboratories. This product is a powerful, standard-grade industrial process detection instrument for field and laboratory use.
Features
●Measurement/output: voltage, current, resistance, frequency, pulse, switch value, among which current output supports active and passive
●Simulate thermal resistance and thermocouple in the form of temperature
●Can simulate two-wire transmitter
●Resistance measurement can be selected in two, three and four-wire ways
●Accuracy is 0.01%
●Two mutually isolated channels, support synchronous measurement and output
●Can provide manual step, automatic step, automatic step and manual step function
●Using 3.5-inch TFT LCD screen with a resolution of 480*320
●The measurement and output data can be displayed at the same time, and the measurement or output data can also be displayed separately
●5000mAh lithium battery power supply
●With automatic power off function, time can be set, suitable for on-site use
●Provide DC24V loop power supply for on-site debugging
●The thermocouple measurement and output provide built-in, external and manual cold junction temperature compensation methods, of which the external reference terminal adopts A-grade Pt100 platinum resistance
●Thermocouple Type：R,S,K,E,J,T,N,B,L,U,XK,WRE325,WRE526
HART function (only ADPC-826B and ADPC-825B support this function): It can completely replace the HART hand-held communicator, set or calibrate the range of the smart transmitter, and force the output current of the smart transmitter to be at a fixed value (such as 20mA, 12mA) , 4mA), set the linear or square root function, can perform HART reset on the pressure sensor of the transmitter, etc.;
