Ectron 1140A - Figure 8-2: Fuse on Analog Assembly

Troubleshooting
Fault: Unit operates in meter mode but not in source
Solution: Replace the fuse on the analog assembly (see Figure 8-2). If the problem
persists, the analog assembly may require repair. Contact Ectron for further
instructions.

Fault: Unit fails alignment
Solution: The analog assembly may require repair. Contact Ectron for further
instructions.
Fault: In thermocouple operation, the output or the meter reading wanders over time
Solution: Ensure that the terminals being used are the active terminals.
Fault: A small (typically 1.5 mV or less) error exists when using either copper or alloy
wires
Solution: Ensure that the correct wire type is specified in the OUTPUT MENU under
MATERIAL. Then, if in the TEMPERATURE output mode, ensure that the correct
thermocouple type is specified in the THERMOCOUPLE MENU.
Fault: Erroneous readings are made using one connector, but not the other
Solution: The analog assembly may require repair. Contact Ectron for further
instructions.
