The selection of the ISIPs is critical. Variations in either value or tolerance from those supplied in the
CIO-DAS48-ISIP will result in inaccurate measurements.
3. Set the input type jumper to the " I " position (see page Error! Bookmark not defined.).
4. Set the DIFF/SINGLE switch to the " 24 DIFF " position (see page 11).
5. Install the board and run the InstaCal calibration procedure for current mode.
After installation, the inputs are committed to current measurement and cannot be used for voltage
measurement.
 To restore the inputs to voltage measurement remove the ISIPs (clip off the SIPs). If you want to de-solder
the SIPs, you must return the board to the factory.
 If you want to re-install the 10k SIPs in RN7, RN8, and RN9 (to have ―Modified-Differential‖ inputs), you
must return the board to the factory.
It is not possible to install only a portion of the ISIPs and have a mixture of current and voltage inputs. You
must install all six SIPs from the CIO-DAS48-ISIP package, and set the input type jumper to the "
I " position.
