Connecting Remote PreAmp to the mainframe
WARNING
Use the supplied preamp cable to connect the Remote PreAmp to the mainframe as follows:
1.
2.
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, bar-
riers, and grounding to prevent contact with conductors. Operator protec-
tion and safety are the responsibility of the person installing the product.
During 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 powering up the
SourceMeter.
Up to 210V may be present on the output and guard terminals. To prevent
electrical shock that could cause injury or death, NEVER make or break
connections to the SourceMeter while it is on or is connected to an external
source.
Potentially hazardous source voltage is routed from the mainframe to the
Remote PreAmp via the preamp cable. Adhere to the following safety pre-
cautions to prevent electric shock:
• The SourceMeter must be turned off before connecting (or disconnect-
ing) the Remote PreAmp to the mainframe.
• When not using the Remote PreAmp, disconnect the preamp cable at
the rear panel of the mainframe. DO NOT leave the preamp cable con-
nected to the mainframe if the other end is not connected to the Remote
PreAmp.
• ALWAYS re-install the plastic safety cover onto the mainframe preamp
connector whenever the Remote PreAmp is not being used.
From the front panel of the SourceMeter, turn the POWER off.
Connect the preamp cable to the Remote PreAmp. The preamp connector on the
Remote PreAmp is labeled "MAINFRAME."
