Check the listing for details. 4-20mA Signal Generator Current Voltage Signal Source w/Display U2S1. Condition: New. Listed at 57.99 USD. 4-20mA Signal Generator Current Voltage Signal Source w/Display U2S1 Features: The generator with is powered by lithium , which can be chargeable. When the is undervoltage, the undervoltage indicator lights will be up, please turn off the generator and the in . If the generator is not used for a long , at least every 2 months to prevents damage. MICRO USB powered 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 powered 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 is ±9.99%, and the voltage output correction 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!
