Never connect the Guard terminal to any output, including the frame/chassis
ground or any other guard terminal. Doing so will damage the M9614A/M9615A.
LF and Low force terminal and frame/chassis terminal
frame/chassis
These terminals are connected together by using the short bar when the
M9614A/M9615A is shipped from the factory. The short bar must be connected to
perform the grounded measurement.
If you want to perform the floating measurement, or if you want to connect
another instrument's ground to the Low force, remove the short bar, and leave the
terminals open. Then use the Low force terminals on the D-sub connector to
connect the other instruments.
