Power cord
The power cord supplied with your 

LT7 

forms part of the measuring circuit of

the instrument. The overall length of this lead must not be altered. 
If the power cord plug is not suitable for your type of socket outlets, do not use
an adaptor. You may change the plug once only  by cutting the cord as close
as possible and fitting a suitable plug. 

The colour code of the cord is:

Earth (Ground)

Yellow / Green

N e u t r a l

B l u e

Phase (Line)

B r o w n

If using a fused plug, a 10 Amp fuse to BS 1362 should be fitted.
Note:  Aplug severed from the power cord should be destroyed, as a plug
with  bare conductors is hazardous in a live socket outlet.
