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 (one per side).

Slide the cover back and lift the cover straight up.
4. Remove the screw holding the current loop option to the motherboard.
5. Disconnect the current loop option PCA from the appropriate connector on the
motherboard (see Figure 3-9).
6. Each connector, J19 and J23, requires two shunts. Place one shunt on the two left
most pins and the second shunt on the two adjacent pins (see Figure 3-9).
7. 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 5.9.3.2.
