7	Cooling vents

☆ Wide output range

 
 

☆ 4-terminals Simulated DC resistance

2-terminals and 4-terminals resistance wiring mode. When calibrating the low value resistance, the four wire system wiring mode can effectively eliminate the measurement error caused by the resistance of the test lead and improve the measurement accuracy.

Compared with the standard physical resistance box, the analog resistance output has the following characteristics:  

a. Continuously adjustable, with better adjustment fineness and sensitivity. 
b. Smaller size and lighter weight. 
c. No influence of transfer switch error, residual resistance error and contact resistance error.    

 

☆ Multiple output\adjustment methods

"Direct output" mode: the value output can be set directly by physical key or touch screen.
