1.2 .3 RANGE SWITCH SETTING
The DIP switch labeled S2 controls the range (gain) settings for both bipolar ranges
(±5V and ±10V), and for the unipolar range (0 to 10V). For location, see Figure 1-1.
Switch S2 has four ganged switches to select an input range for the analog inputs
(Figure 1-4).
Refer to Table 1-3 to determine the correct positions of switches S2-1 through S2-4
for the range you desire.
These switches control the analog input range for all eight channels.
Table 1-3. Range Select Switch (S2) Settings
2.44mV / bit 0 to 10V 1 Up Down Down Up
4.88mV / bit ±10V 0.5 Down Up Up Down

RESOLUTION RANGE GAIN S4 S3 S2 S1
NOTE: Up = open; Down = closed.
Positions other than those listed are not valid.
