Features
- Excellent port protection performance, both the output and measurement terminals can withstand up to 300V AC high voltage mis-connection without causing hardware damage. For a long time, the calibration work of field instruments usually requires operators to carefully distinguish between strong and weak electricity, and wiring errors may cause serious hardware damage, The new hardware protection design provides a strong guarantee for protecting operators and calibrators.
- Humanized design, adopting an embedded intelligent operating system, supporting sliding screen and other operations, simplifying the operation interface while having rich software functions. Adopting the human-computer interaction mode of touch screen + mechanical buttons, the capacitive touch screen can bring an operation experience comparable to that of a smartphone, while the mechanical buttons can help improve the accuracy of operation in harsh environments or when wearing gloves. In addition, the calibrator is also designed with a flashlight function to provide lighting for low-light environments.
- Three reference junction modes can be selected: built-in, external, and custom. In the external mode, the intelligent reference junction can be automatically matched. The intelligent reference junction has a built-in temperature sensor with a correction value, made of tellurium copper. It can be used in combination or split into two independent clamps according to needs. The unique design of the clamp mouth makes it easy to bite conventional wires and nuts, so as to obtain more accurate reference junction temperature with more convenient operation.
- Measurement intelligence, electrical measurement has automatic range, and automatically recognizes the connection mode when measuring resistance or thermal resistance, eliminating the cumbersome operation of selecting range and wiring mode during measurement.
- Diversified output setting methods, values can be input via the touchscreen or set digit-by-digit using buttons. It also features three stepping modes: ramp, step, and sine, the step cycle and step length can be freely set.
- Measurement toolbox, with multiple built-in applets, can perform forward and reverse conversions of temperature values and electrical values of thermocouples and thermal resistors, and supports mutual conversions of more than 20 physical quantities in different units.
- Curve display and data analysis functions, can be used as a data recorder to record and display measurement curves in real time, and perform diverse data analysis on the recorded data, such as standard deviation, maximum, minimum, and average values.
- Task functions (Model A, Model B), built-in calibration task applications for temperature transmitters, temperature switches, temperature instruments, and thermal response time, can quickly create tasks or select templates on site, automatically perform error judgment, and output calibration process and result data after task completion. Among them, the thermal response time calibration function can automatically judge the start and end points of the step response, calculate the step response time and time constant, and export test data and step curves.
- HART communication function (Model A), with a built-in 250Ω resistor, combined with the built-in isolated LOOP power supply, it can communicate with HART type transmitter without other peripherals, and can set or adjust its internal parameters.
- Expansion functions (Model A, Model B) supporting pressure measurement, humidity measurement and other modules. Without affecting the original measurement and output functions, the calibrator automatically recognizes the module after it is inserted into the port and enters the three-screen mode.
