It is a beautiful and durable instrument, which is an ideal tool for calibrating, maintaining and overhauling thermal instruments.
Function
1. Outputs V, mV, mA, Ω, Hz, and can also simulate thermocouple or RTD signals.
2. Measures V, mV, mA, Ω, Hz, pressure, calibrates pressure switches, and can also measure temperature using thermocouples or RTDs.
3. Measurement and output can be performed simultaneously and isolated from each other.
4. Provides 24V DC power supply, isolated from measurement and outputs.
5. High-resolution display, good human-computer interaction interface;
6. Support step output, can be programmed with common step signals and step intervals, and support two modes of automatic step or manual step;
7. Using Pt100 temperature probe for cold end temperature compensation, support ambient temperature tracking or constant temperature setting two modes;
8. Multi-functional, programmable unit conversion function, can be V, mA output or measurement signals into other unit quantities (℃, ℉, % , kPa, MPa, psi, mmHg, mm H2 O, m3 / s, m3 / min, m3 / h, L / s, L / h, L / min, m, ?) ;
9. When outputting mA signal, it supports two modes of mA source or analog transmitter;
10. When outputting and measuring thermocouple ℃ signal, display the corresponding mV value;
11. When outputting and measuring RTD ℃ signal, display the corresponding Ω value;
12. When outputting and measuring Ω signal, it supports two, three and four-wire modes;
13. When outputting Hz signal, the amplitude can be set, supporting square wave or sine wave mode;
14. Provide 24V DC circuit power supply and measure the mA signal in the circuit;
15. Can be in any digit of the output value, signal fine-tuning;
16. Can lock or unlock the measurement value when measuring the value;
17. Can collect the minimum and maximum value and calculate the average value when measuring the value;Can store on-site inspection data, use the communication software data transcription function for management;
18. Can store on-site inspection data, use the communication software data transcription function for management;
19. Strong lithium 7.4V/4800mAh, can continue to work more than 12 ~ 30 hours;
20. Output and measurement items can be calibrated.
