Example: Resistor
Divider Configuration
Any channel can be configured as a resistor divider connected to the
normally open (NO) contact of the Form C relay. The user-supplied SIP
resistor can be replaced by a standing resistor with it inserted in the solder
hole of the SIP and a solder hole directly across from it. The row of solder
holes is connected to V24-31.
Figure 1-17 shows the voltage solder holes and identifies the voltage to
which the row is connected. For this example, resistor R25 and SIP resistor
pack RP24-31 are to be added. Set one configuration jumper as shown in
Figure 1-17 (LP/DIV).
