The generator uses the encoder to adjust the current and voltage output and modify the parameters. The encoder button is used to move the cursor. Press the button once, the cursor moves to the upper position by one bit (with a flashing prompt), and the cursor position is used to indicate the different output adjustment amount corresponding to one pulse of the encoder (0.01, 0.1, 1, 10 (mA or V)).

Features:
The generator with Bat-tery is Po-wered by lithium Bat-tery, which can be chargeable.
When the Bat-tery is undervoltage, the undervoltage indicator lights will be up, please turn off the generator and charge the Bat-tery in Tim-e.
If the generator is not used for a long Tim-e, charge at least every 2 months to prevents Bat-tery damage.
MICRO USB Po-wered and charged.
1）Current Output
The current output encoder is rotated to right, the output is increased; and it is rotated to left, the output is decreased. You can change the position of the cursor by the encoder button to change the different output increment and decrement (0.01mA, 0.1mA, 1mA, 10mA).
2）Voltage Output
The voltage output encoder is rotated to right, the output is increased; and it is rotated to left, the output is decreased. You can change the position of the cursor by the encoder button to change the different output increment and decrement (0.01V, 0.1V, 1V, 10V).
3）24 Voltage Output 24V will be output directly when Po-wered on.
4）Output Correction
Press and hold the current output encoder button for more than 2s to enter the correction interface. The current output correction range is ±9.99%, and the voltage output correction range is ±9.99%. The corresponding current and voltage values can be corrected by rotating the corresponding encoder. Press the voltage encoder button, the settings will be saved and press the current encoder button, the setting will be canceled.
Note: Due to the output chip limit, the minimum output voltage and current cannot be 0!
