Shunt Resistor Selection

The IL78A has a Internal and External shunt

selection jumper located between the two wiring

connectors. Below are the appropriate wiring and

jumper selections depending on the application

using the recommended 7 wire configuration.

When more than one IL78A is being used in the same measurment setup, beat frequencies can be produced by

the excitation clock oscillator. To prevent this, the user should declare one of the IL78A units as a Master via

switch 6 on the front panel. The other units should be switched to Slave and wired as shown with the SYC

terminals connected and a separate Power Common wire. If the units share a common power supply, the

Power com terminal should be connected at the modules.
