PLC 4-20mA Signal Generator Current Transmitter Tester [24V] [Two Wire]

Description:
PLC 4-20mA high precision current transmitter tester, 24V, two wire, with back-lighted LCD.
9 segments programmable output can simulate the dynamic test in a real environment. Every segment can set the running time (t), initial current (A), termination current (b).
Digital rotary encoder adjustment (if you use the potentiometer, the value of the impedance will change).
Can be reversed connected safely (two-wire system, no matter positive or reverse connecting, the meter can work normally and will not burn).
High accuracy, good linearity (display accuracy "0.05", the real output accuracy is + /- 0.5%)
Super low power consumption, no heat emission, stable output.
Perfect and beautiful shell, simple and convenient installation, can be installed on panel door easily.

Features:
Output current: 3 ~21mA
Power supply voltage: DC 24V ± 20%
Sampling impedance: 10 ~500ohm
Display accuracy: 0.01
Output accuracy: +/-0.5%
Overall dimension (front): 79.5mm x 42mm
Overall dimension (back): 72.5mm x 39.5mm

Operating instruction:
Two working modes: Manual mode  and  Dynamic output mode:

Manual Mode:

1. To adjust output current: Rotate the encoder knob, clockwise to increase current while counter-clockwise to decrease current.
2. To save output value: short press the encoder knob and then release, the screen will display "...", which means the value is saved successfully. When you turn on the product next time, the output will be the value you saved. When debugging the product, we need to adjust the output value, but the output value will not change when you turn on the product unless you press the knob.

Dynamic output mode: 

Dynamic output mode means cyclic automatically output the set programmable curve.

1. Parameters setting: Long press knob of the encoder for about 5 seconds to enter into the setting status.
2. Choosing the working mode: The screen will display FUNX. X means the segment of the curve. Then you can rotate the knob to adjust the value of X. If X=0 which means no curve, manual mode is chosen. If X>0, the dynamic output mode is chosen.
3. After choosing the working mode, press the knob. If X=0, it means exiting mode setting and enter into manual mode. If X>0, it means to enter into setting the first segment of the curve.
4. There are three parameters needing to be set in every curve, running time "", initial current "AXXX", termination current "". When you enter into the setting interface of the 1st curve, the screen will display "t1XX" and then you can rotate the knob to adjust the value of XX. The range of running time is 1-99 seconds.
5. Press the knob again to enter into setting the initial current, the screen will display "A1XX" and then you can rotate the knob to adjust the value of XX. The range of current setting is 3-21mA.
6. Press the knob again to enter into setting the termination current, the screen will display "b1XX" and then you can rotate the knob to adjust the value of XX. The range of current setting is 3-21mA.
7. And so on, for the following set of the curve. The setting status will exit automatically when all the parameters of the curves are set.
8. If you want to change one of the parameters and the following parameters remain unchanged, you can adjust the parameter to the value you need and then long press the knob for about 5 seconds which can exit the setting status directly.
