When pressed the ‘REV’ button allows current flow in the ‘reverse’ 

direction

 

 

 

When pressed the ‘INC’ button increases the current by one level 

(10mA max.) 
 

 

When pressed the ‘DEC’ button decreases the current by one level 

(100nA min.)

 

 

 

When pressed the ‘

Ω  /

 

’ 

button changes the display from mV to 

ohms/square. Pressing the button again reverts to a mV display.

 

 

 

When pressed the ‘Hi’ button switches the unit to ‘High’ resolution 

 

 

When pressed the ‘Low’ button changes the unit to ‘Low’ resolution
