3.4.5.1. 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.
5. Place a shunt between the leftmost two pins of the connector (see Figure 3-9).
6. Reattach the top case to the analyzer.
The analyzer is now ready to have a voltage-sensing, recording device attached to that
output.
CAUTION – Avoid Warranty Invalidation
Printed circuit assemblies (PCAs) are sensitive to electro-static discharges too small
to be felt by the human nervous system. Damage resulting from failure to use ESD
protection when working with electronic assemblies will void the instrument warranty.
See A Primer on Electro-Static Discharge in this manual for more information on preventing
ESD damage.
