Optional Hardware and Software Model 360E Instruction Manual
5.2.1. Converting Current Loop Analog Outputs to Standard Voltage
Outputs.
NOTE
Servicing or handling of circuit components requires electrostatic discharge protection,
i.e. ESD grounding straps, mats and containers. Failure to use ESD protection when
working with electronic assemblies will void the instrument warranty.
See Chapter 12 for more information on preventing ESD damage.
To convert an output configured for current loop operation to the standard 0 to 5 VDC output operation:
4. Turn off power to the analyzer.
5. If a recording device was connected to the output being modified, disconnect it.
6. 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.
7. Disconnect the current loop option PCA from the appropriate connector on the motherboard (see Figure
5-1).
8. Place a shunt between the leftmost two pins of the connector (see Figure 5-1).
6 spare shunts (P/N CN0000132) were shipped with the instrument attached to JP1 on the back of the
instruments keyboard and display PCA
9. Reattach the top case to the analyzer.
10. The analyzer is now ready to have a voltage-sensing, recording device attached to that output
