Handheld signal generatorIt can achieve the output and measurement of multiple signals. The product uses a microcontroller as the CPU, integrating the latest large-scale digital conversion integrated circuit and large screen LCD display technology. It has output, measurement, manual, and 24VDC power distribution functions, and all four functions can work simultaneously, displaying output and measurement values as well as corresponding ITS-90 standard values (thermistor and thermocouple) on the same screen.
Usage characteristics:
1. Compact, easy to carry and hold.
2. Durable and reliable, the support frame and hook holes on the back are suitable for on-site use.
3. Large display screen, measurement and output can be displayed simultaneously.
4. Measurement of voltage, current, resistance, and output of voltage and current.
5. Measurement and output of 8 types of thermocouples (K, E, T, J, S, R, N, B), and measurement of 2 types of thermal resistors (PT100, Cu50).
6. The measurement output of thermocouples and thermal resistors has ITS-90 international standard millivolts and corresponding display of resistance values.
7. Voltage and current measurements can display percentages.
8. Thermocouples have automatic or manual compensation functions for measurement and output.
9. There are multiple ways to input output values.
10. It can achieve rapid mutual check between resistance value and temperature value, millivolt value and temperature value.
11. Equipped with a large capacity rechargeable battery, it can work continuously for 5-7 hours on a single charge (depending on the working condition).
12. Large screen LCD with backlight display, Chinese menu operation.
13. The button sound and backlight can be controlled, and the last set state can be maintained every time the device is turned on.
