Product Review
Overview:
GeekTeches DC signal generator is with multi-ring (5 * 360) potentiometer knob operation. In response to the output immediately after adjustment, no delay. Adjust the actual fineness of up to 0.01mA, operate freely.
Features:
- LCD (with backlight).
- Digital rotary encoder adjustment (the use of potentiometer, easily affected by temperature and humidity, the resistance value will change).
- High precision, good linearity
- Imported chips, ultra-low power consumption, no heat, more stable output.
- The shell is beautiful and easy to install.
Specifications:
* Multi-ring (5x360) potentiometer knob operation, stepless fine adjustment, in response to the output immediately, no delay
* Potentiometer to adjust the actual fineness of up to 0.01 mA
* Power supply: DC12-30V,DC 12V or 24V, current 18mA, power port has a polarity protection, power reverse does not work, do not burn components.
* 4-bit 0.36-inch LED, the display range: -1999-9999, can be set to the number of 0,1,2,3 decimal points
* 20mA output: the maximum output current of 24mA.
* 12V DC power supply: output load impedance range between 0-350 ohms
* 24V DC power supply: output load impedance range between 0-800 Ohms
* The test output is normal, you can use a multimeter (DC current file) short "4-20mA output" terminal value and the comparison shows that the multimeter readings are the same.
Included:
1x 4-20mA Signal Source Signal Generator
Q&A:
1. Does this also generate a linear voltage signal beside a current signal?
- No, this does not generate a linear voltage signal, it only generates a current signal.
2. What is the maximum frequency?
- This precision potentiometer outputs only DC. The purpose is for setup and calibration of 4-20mA process control instruments.
