Fast Adjustment -- digital encoder adjustment:
- Press down the knob, and the current adjustment position moves left circularly (the adjusted position flashes). Rotate the knob clockwise/counterclockwise to directly add/subtract 1 (X0.01/0.1/1/10V) current, and the adjustment is fast and simple.

- The product adopts a higher cost digital encoder instead of a low-cost analog potentiometer, which gives the product the following advantages:
1. More accurate adjustment (strictly increase or decrease by 1 when turning 1 grid, the output of the potentiometer changes a lot when slightly turned by hand).
2. Faster adjustment (press the encoder to adjust the position and cycle to the left, which can directly adjust the voltage of 0.01-10V, convenient and fast)
3. Long term stability (the encoder adopts a CNC scheme, avoiding problems such as temperature, humidity, aging and wear of the potentiometer, and vibration to change the resistance value of the analog potentiometer)
4. Higher accuracy and repeatability (the output of the analog potentiometer will change as long as it touches the knob (even if the product is not powered on), and the encoder will not be powered on. Turning the knob on the next time will still maintain the output, which is very suitable for situations where multiple power on but the same test parameters are required)

Express Mode:
- Lightly turn the knob to directly output preset values, with up to 9 shortcut points to set.

Automatic Curve Scan:
- Up to 20 curves can be set.
- Next time when powered on, automatically scan the voltage output according to the previously set curve.
- Very suitable for various performance tests and long-term aging tests of the product.

Online Communication (for Modbus version):
- The onboard isolation 485 communication circuit adopts the standard modbusRTU protocol and supports for 0X03 and 0X06 instructions.
- Module outputs can be remotely controlled using upper computer software such as modbusPoll, and multiple devices can be controlled simultaneously using the 485 bus.

Precaution:
- The product is powered by DC, do not use AC power.
- Do not supply power beyond the nominal voltage range.
- Please use within the nominal driving load range (exceeding the range may cause the actual output voltage to be lower than the displayed control voltage)

FAQ:
Q: What is the situation when there is no display after the product is powered on?
A: 1. Check if the power supply voltage is normal and whether it is between 6 and 28V.
2. Check if the wiring is correct and secure.
3. Check if the power supply is restricted by current, and a certain amount of current is required when the product is powered on and started.

Q: What is the situation where the output voltage value decreases after the product output is connected to the load?
A: This product outputs a voltage signal, not a power supply! The output carrying capacity is limited. The output current capability is within ±20mA.

Q: Can battery be used for power supply?
A: Sure. The product has a wide power supply voltage, and as long as the battery voltage is within the nominal power supply range of the product, battery can be used.
