Parameters Programming Examples
*F001, F006 represent parameters code number.
• “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 “= = = = (or +–+ or —- depends on presetting)”.
Figure 4-5: Press down knob, if password is correct, displays “F002”, Otherwise displays “Err” and Exit.
Figure 5-6: Rotate Knob till it 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 or 20mA). A high precision multimeter needed in that step.
Figure 7: Press down knob “OK” to Save. Otherwise, parameters will not be saved if there are no actions for more than 10 seconds.
