Single Booster - Connections At The Cell - Ametek PMC BOOSTER Series Hardware Manual

Single Booster – Connections at the Cell
Connections at the cell are recommended to be made in 4-terminal mode, with distinct connections for
the voltage and current terminals. This configuration minimizes contact resistance from the leads. The
picture shows the voltage leads being closest to the device under test and the current lead on the
outside. The device under test here is a 0.1 Ohm resistor 25W (P/N 738190). In testing larger currents,
a device should be selected that is low impedance to avoid voltage overloads – here 10 Amps on 0.1
Ohms will generate 1 V. Also, the thermal capacity of the resistor should be considered: 10A and 1V will
generate 10W, sufficiently below this resistor.
As with all instrumentation, it is recommended to be disconnected from the device under test both
when not being controlled as well as during system power OFF and ON.
