All sensor connections are summarised in the diagram below.
3.3.1 DC VOLTAGE INPUTS
The unit has two individual voltage inputs. One supports millivolt inputs ( up to
100mV ), and the other, voltage inputs up to 10 volts.
If the voltage input to be measured is to be no greater than 100mV it is connected to
the millivolts input. If the signal is less than 10 volts but greater than 100mV, it is
connected to the Voltage input. Any voltages greater then 10 volts may still be
measured, but must be divided down first. Each of these cases is discussed in more
detail below.
3.3.1.1 MILLIVOLTS INPUT
This input accepts signals up to
+/-100mV in normal operation. The
signal source must be connected to
pins 4 and 5 as shown opposite.
