Chapter 3 Switch Settings
Switch Positions
e.g. The switches in Figure 3.1 are depicted as ALL ON.
Figure 3.1 Output Settings–Switch 4
Use switch 4 to select the required output and, if
required, the low pass filter and 5V Excitation.

N.B.
Full scale output on the voltage ranges is achieved with a bi-polar (±) input
Note 1 Negative inputs can be accommodated on the current output ranges by setting the ‘Zero’ switch SW2 to
+50% (Table 3.8) and setting SW1 to twice the required mV/V setting (Table 3.6).

Switch settings (0 = Off 1 = On X = Don’t Care)
Important: Low pass filtering is switched into operation by setting SW4/6 ‘ON’

and SW4/7 ‘OFF’
↓
.
Reverse these settings to bypass the filter.
It should be noted that either one of these switches MUST be on but not BOTH
