Adjustable 4-20ma Signal 24V Current Voltage Calibrator source 0-10V Constant Current Source Simulation

1 . Technical Parameters: Due to the output ch limit, the minimum output voltage and current cannot be 0! ◆Active current output: 0-22 mA (the minimum output is about 0.06mA), load: 0-550Ω ◆Paive current output: 0-22 mA (the minimum output is about 0.06mA), external power supply up to 30V; load: 0-550Ω ◆Voltage output: 0V-12 V (the minimum output is about 0.05V) ◆24V voltage output: drive current: 35mA (Do not more than 35mA) ◆The with battery is powered by lithium battery, which can be chargeable; The version without battery is directly plugged into the 5v charger ◆When the battery is undervoltage, the undervoltage indicator lights will be up, please turn off the and charge the battery in time. ◆If the is not used for a long time, charge at least every 2 months to prevent battery damage ◆MICRO USB powered and charged. ◆Operating environment: 0 °C - 50 °C without condensation ◆Size: 90mm*70mm*28mm

3. Operation Instructions 1 )Overview The r uses the encoder to adjust the current and voltage output and modify the parameters. The encoder on is used to move the cursor. Pre the on once, the cursor moves to the upper position by one bit (with a fing 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)). 2 )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 on to change the different output increment and decrement (0.01mA,0.1mA,1mA,10mA) 3 )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 on to change the different output increment and decrement (0.01V,0.1V,1V,10V). 4 )24 Voltage Output 24v will be output directly when powered on. 5 )Output Correction Pre and hold the current output encoder on 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. Pre the voltage encoder on, the settings will be saved and pre the current encoder on, the setting will be canceled. 5 ,Charging Notice The 5v USB charger will charge the internal battery regardle of whether the is powered on or off . It is recommended that the charger's output current be greater than 500mA. Warnings: Keep away from high temperature during charging or use; do not use or charge for a long time without being guarded!The instrument charging voltage is DC5v, please do not apply a voltage higher than 5.5v to the charging port of the instrument, which may cause instrument fai or accident! This instrument is mainly developed with debugging test. It can be used for PLC signal debugging and calibration, proce instrument debugging, vae positioning test calibration, and is not suitable for high-precision instrument calibration. Please use it in suitable occasions!
