7.3.1.2  Checking Medium Current Range 

A.  Connect the Load, DC source, DMM, current shunt as Figure 7-1  shows. Use DMM (I) 

to measure the voltage that passes through the shunt resistor measurement port, and 
get the load current.  

B.  Select the right range for the current shunt resistor. Press 

 till VFD shows 

CC

 

and press 

 to light up the M range LED indicator. 

C.  Press 

 to enter into CC Mode for setting. Use rotary knob and 

or

 

 to 

program the current listed in Table 7-4 .  

D.  Turn on the DC source and set output voltage to 5V. Set current limit of DC source 

larger than the set current of Table 7-4. Press 

 to enable the load and wait for 30 

seconds. Then record the shunt current and the front panel displayed readings. The 
current of load can be recorded from current shunt = DMM (I) voltage/current shunt 
resistor.

 to enable the load and slowly decrease the dc source voltage until 

DMM(V) display reached minimal operation voltage of the Table 7-5 for testing model. 
The current of load can be recorded from current shunt = DMM (I) voltage/current shunt 
resistor.
