5.4.1. 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 Section 14 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:
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 on both sides that fasten the top cover to the unit.
Slide the cover back and lift straight up.
4. Remove the screw holding the current loop option to the motherboard.
