Power-up
During the power-up, voltage spikes may appear on the terminals of 
the SourceMeter. These voltage spikes could be at hazardous levels 
(42.4V peak) and could damage sensitive DUTs. Never touch external 
circuitry or the test leads when powering up the SourceMeter. It is good 
practice to always disconnect DUTs from the SourceMeter before pow
-
ering up the unit.
To prevent electric shock, test connections must be configured such 
that the user cannot come in contact with conductors or any DUT that 
is in contact with the conductors. Safe installation requires proper 
shields, barriers, and grounding to prevent contact with conductors. 
Operator protection and safety are the responsibility of the person 
installing the product.
When handling the SourceMeter, NEVER touch the heat sink located 
on the left side of the case. This heat sink could be hot enough to cause 
burns.
Line power connection
The SourceMeter operates from a line voltage in the range of 100 to 240V at a fre-
quency of 50 or 60Hz. Line voltage and line frequency are automatically sensed. 
Therefore, there are no switches to set. Check to be sure the operating voltage in 
your area is compatible.
CAUTION Operating the instrument on an incorrect line voltage may cause 
damage, possibly voiding the warranty.
Perform the following steps to connect the SourceMeter to line power and turn it 
on:
1. Before plugging in the power cord, make sure the front panel power switch 
is in the off (0) position.
2. Connect the female end of the supplied power cord to the AC receptacle on 
the rear panel.
