The front panel contains 5 rows of high-quality gold-plated terminals. All are suitable for 4 mm
plug insertion on screw compression connectors. For current connection, large 25 mm diameter
terminals are provided. The outer ring can be completely removed for clamp connections.
Be aware that excessive tightening of the clamp can cause damage to the terminal thread
It is important that the correct good quality spade terminations are used for currents above 50 A
since arcing can cause damage to the terminals.
Connections to the voltage terminals is less critical, but to minimise thermally generated EMF
errors it is recommended that gold plated 4mm plugs are used.
Care should be taken to ensure that current is only injected into the two large current terminals;
the voltage terminals are used only for the measurement of voltage.
