100% brand new and high quality

Features:
No-source two-wire 4-20mA current loop, wiring compatible with 2, 3, 4 wire system
9 programmable output (can simulate the actual environment of dynamic testing, each section can be set up t running time /A current /b current).
Digital rotary encoder adjustment (the use of potentiometer, easily affected by temperature and humidity, the resistance value will change).
Can be connected to the positive and negative (two-wire system, no matter how wiring, can work, will not burn meter).
High precision, good linearity (Output accuracy：±0.5％；Display accuracy：0.01)
Coarse and fine adjustment modes can be set for quick and accurate adjustment
Output range can be set: 4-20mA (control device) / 3-21mA (debug signal)
Display mode: Actual current/100.0%/50.0Hz, LCD (with backlight).
Linear output, calibratable
Can be set to automatically store output values: automatic / manual
2-9 quick adjustment output points can be set
Imported chips, ultra-low power consumption, no heat, more stable output.
The shell is beautiful and easy to install.

System operation：
Parameter Settings:（Rotate one grid clockwise is "+" Rotate one grid counter-clockwise is "-", Press the knob. is"Confirm"）
1. Press and hold the knob for 2 seconds to enter the parameter setting, Display parameter number "F001", Then press "Confirm ", to Set the value of parameter "F001", =0 is coarse tuning; =1 Fine tuning; Then press "Confirm" to save its value.
2. When the parameter number "FXXX" is displayed, "+" "-" Rotation modification parameter number; Enter the password first "+ - - +", To enter the F002 parameter; Enter the password first "+ - + -", To enter the F100 parameter; Enter the password first "- + - +", To enter the F200 parameter.
