Current Source and Amplifier: 

Resistance is 

measured by connecting the current source to 
the resistance to be measured and measuring 
the voltage with the input amplifier. 

 

Test Receptacle: 

This supplies power to the 

unit under test, 110 VAC rated at 15 Amps (220 
VAC). The rocker polarity switch selects 
NORMAL, OFF and REVERSES polarity in the 
test receptacle. 

 

Display: 

All measurements are displayed on a 

3-1/2 digit LED display. 
Over range is indicated by showing a 1 in the 
most significant digit.
