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 screw located in the top, center of the front panel.
Remove the screws fastening the top cover to the unit (both sides).
Slide the cover back and lift 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 3-10).
6. Each conn
ector, 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 (see Figure 3-10).
7. Reatta
ch the top case to the analyzer.
The analyzer is now ready to have a voltage-sensing, recording device attached
to that output.
