WARNING
THE LINE POWER CORD MUST HAVE AN EARTH CONDUCTOR TO AVOID RISK
OF SHOCK. THIS INSTRUMENT MUST BE CORRECTLY EARTHED.
Input sockets are all 4mm safety type, the voltage pairs contacts are low thermal gold plated for
minimum thermal EMF.
The 8000 series multimeter inputs have been designed to allow instruments to be calibrated
minimising connection changes. There are 2 pairs of inputs, a high current input and a single guard
input terminal :
When an output terminal pair is not active they are completely open circuit and isolated from the
other outputs (note : a 30A shunt is permanently connected between the current negative and 30A
terminals). As only one pair is active at a time on (except on 4 wire ohms) they may be combined
together if required to match the input arrangement.
One example common configuration of a instrument’s inputs is a single common low with a voltage,
current and high current input. To match this to the multimeter, simply connect the 3 low outputs of
the multimeter together and connect the voltage, current & high current outputs to the appropriate
meters input . Note that when measuring ohms, the multimeter will use the voltage input terminals in
2 Wire mode.
A second example where the UUT instrument has separate voltage and current inputs, often using 4
wire ohms on both pairs. In this case simply connect the voltage and current outputs to the meter’s
inputs, the multimeter will use both the voltage and current pair on 4 wire ohms.
