U1190A Series Quick Start Guide

Resistance measurement

Set up your clamp meter to mea-
sure resistance as shown. Probe 
the test points and read the dis-
play.

 

 

 

Continuity test

Set up your clamp meter to test 
for continuity as shown. Press 

 to switch to the continuity 

test function (

 is shown on the 

display).

 

To avoid possible damage to 
your clamp meter or to the 
equipment under test, dis-
connect the circuit power 
and discharge all high-volt-
age capacitors before mea-
suring resistance or testing 
for continuity.

The beeper will sound and the 
backlight will flash when the 

 

circuit-under-test is shorted.
