Safety Guidelines 

 

General 
Guideline 

 CAUTION 

 

Do not place any heavy object on the LCR-800. 

 

Avoid severe impact or rough handling that 
leads to damaging the LCR-800. 

 

Do not discharge static electricity to the LCR-
800. 

 

Do not block or obstruct the cooling fan vent 
opening. 

 

Do not perform measurement at circuits directly 
connected to Mains (Note below). 

 

Do not disassemble the LCR-800 unless you are 
qualified as service personnel. 

 

(Measurement categories) EN 61010-1:2001 specifies the 
measurement categories and their requirements as follows. LCR-800 
falls under category I. 

  Measurement category IV is for measurement performed at the 

source of low-voltage installation. 

  Measurement category III is for measurement performed in the 

building installation. 

  Measurement category II is for measurement performed on the 

circuits directly connected to the low voltage installation. 

  Measurement category I is for measurements performed on 

circuits not directly connected to Mains.

 

Power Supply 

 WARNING 

 

AC Input voltage: 100V-240V, 50-60/400Hz 

 

The power supply voltage should not fluctuate 
more than 110V-240V ±10%. 

 

Connect the protective grounding conductor of 
the AC power cord to an earth ground, to avoid 
electrical shock. 

Fuse 

 WARNING 

 

Fuse type: FUSE 5TT 3A/250V  

 

Make sure the correct type of fuse is installed 
before powering up.
