Converting Current Loop Analog Outputs to Standard Voltage Outputs
To convert an output configured for current loop operation to the standard 0 to 5 VDC
output operation:
1. Turn off power to the analyzer.
2. If a recording device was connected to the output being modified, disconnect it.
3. Remove the top cover
 Remove the set screw located in the top, center of the rear panel
 Remove the screws fastening the top cover to the unit (four per side).
 Lift the cover straight up.
4. Disconnect the current loop option PCA from the appropriate connector on the
motherboard (refer to Figure 3-8).
5. Each connector, J19 and J23, requires two shunts. Place one shunt on the two
left most pins and the second shunt on the two pins next to it (refer to Figure
3-8).
6. Reattach the top case to the analyzer.
The analyzer is now ready to have a voltage-sensing, recording device attached to that
output.
Calibrate the analog output as described in Section 5.9.3
