  LC1 User Manual 

Note 1: Derived from Host Instrument 

Note 2: Excluding load cell excitation current 

‘(*display only)’ denotes that the specification applies to the on-board display only, not the Host instrument. 

CE Approvals 

European EMC Directive  2014/30/EU 

BS EN 61326-1:2013 
BS EN 61326-2-3:2013 

Wiring Conditions 

Load Cell and Host cable connections should use individually screened twisted multi-pair cables (e.g. Farnell 
118-2117)
Terminate all screens at ‘SCR’. SCR should be connected to a good Earth. The earth connection should be of
sufficient cross sectional area to ensure a low impedance to attenuate RF interference.
