1) LCD will display 

OL

 if failing to insert 

temperature sensor into temperature gear. Clamp 
meter will display current indoor temperature after 
user inserting temperature sensor.
2) Temperature protection gear of the machine 
is plug-in resistance (R59) of 1K

. Electrified 

conductor cannot be inserted into input jack 
during temperature measurement to avoid 
resistance burnout.

     Please do not loosen trigger suddenly. As a 
sensitive device, Hall element will be sensitive to 
heat and mechanical stress to different extents 
except magnetic sensitivity. Collision will cause 
short-term reading variation. Please open the 
clamp head by pressing trigger then fetch 
measured conductor by clamp head and loosen 
trigger slowly until it is closed completely. Please 
check if measured conductor is in the middle of 
clamp head or not. Additional error may be caused 
if failing to place it in the middle of clamp head. 
Clamp meter can measure a current conductor 
once and measurement reading error may be 
caused if measuring two or more current 
conductors at the same time.
