Precision Adjustable 4-20mA 0-5V 0-10V Generator 


New Features:

• Output voltage range: -10V to 10V., 2/3/4-wire 0-22mA sink or source signal output.output range and precision are programmable and adjustable.
• Have 9 x fast signal output points setting, more convenient to do debugging.
• More tough high quality wiring terminal block.
• Refined user-friendly external shell, refined accurate encoders' knob to adjust output signal, more slim size.
• Support 24V operating power supply via wiring terminals and 5V from USB port, can be used in indoors or outside industrial site.
• 1000mAH 3.7V re-chargeable battery embedded inside, very convenient to use.
• High precision 0.01V, 0.01mA output and LED display output signal value accurately.
• Adjusting steps can be fine adjustment or rough adjustment, switchable.
• Brightwin signal generator has switchable display modes: actual current value, 0-100 (%), 0.0-50.0 (Hz).
• Have short-circuited protection circuits and polarity reverse connection protection circuits.
*Its default output range is 0-10V, 0-20mA, user can adjust it to make it output -10V to -10V, 4-20mA, etc, output ranges.

Parameters Programming Examples:

>> Modify "F001" Coarse/Fine adjustment mode:



>> "F006" Precision calibration steps explanation: 
*When doing F006 precision calibration, please do adjust the signal generator output to 10V or 20mA firstly.
Figure 1→2:Press down and hold Knob for 2 seconds till it displays parameter code: "F001";
Figure 2→3: “+” Clockwise rotation once, Display“- - - -”;
Figure 3→4: Input Password “+ – – +”, Display“- - - -”;
Figure 4→5: Press “OK”, If password is correct, displays “F002”, Otherwise displays “Err” and Exit;
Figure 5→6: Rotate Knob till displays “F006”;
Figure 6→7: Press down the knob “OK” to set the value of “F006”, and then modify the value so that the actual output signal value (measured by high precision multimeter) equals to the value displayed in LED panel (10V/20mA); A high precision multimeter needed in that step.
Figure 7→ : Press down knob “OK” to Save. Otherwise parameters will not be save if there are no actions taken for more than 10 seconds.
* Its output range and display mode setting methods are the same to that steps above, please contact us to get user manual or technical support.
Battery recharging time required is 3-4 hours. When recharging the battery, the LED screen is on (cannot be off), and it can automatically stop to recharge the battery once it has been fully charged. It provides convenience for user to use power bank or 5V, 1A out AC/DC power adapter to recharge it and use it to do calibration at the same time. Please refer to the User Manual to get more details.

Parameters Programming Insructions

1.Press down and hold button for 2 seconds to enter into parameter setting states, then LED meter displays  "F001" (F001 is Parameter Code Number);
2.Turn the Knob to change the parameter code number (When entering into “F002”, user needs to enter password "+ - - +" first. );
3.When displaying parameters code number, Press down knob "OK" to enter into the corresponding parameter value setting state, then rotate knob to modify the parameters.
4.Press down the knob "OK" to save parameters setting and exit. LED meter displays next parameters code number ( If haven't enter the password, the signal generator will be returned back to normally adjusting mode after setting "F001" value );
5.Rotate the knob directly till the last parameter code number "Fend" is displayed, then press down the knob to confirm and save.
The parameters setting is completed, and the signal generator returns back to normally operating status. 
6.In parameters setting process, if no any operation to the generator for more than 10 seconds, the signal generator will exit setting status and return back to normally operating status.
