Maintenance
This section contains information you can use to clean and maintain your
equipment.
Inspecting and Cleaning
Remove accumulated loose dust from the TekConnect Probe Interface Module
and sampling module with a soft cloth or brush. Remaining dirt may be removed
with a soft cloth dampened with a mild detergent and water solution, or use
isopropyl alcohol.
Do not immerse any equipment in cleaning solutions or use abrasive cleaners.
CAUTION. To pr event damage, avoid using cleaning materials that contain
acetone, benzene, toluene, xylene, or similar solvents.
Troubleshooting
If you encounter problems installing or operating the TekConnect Probe Interface
Module, try the following troubleshooting procedures.
To verify the interface module and microcontroller are functioning properly,
perform the following steps:
1. Attach a valid probe to the TekConnect input:
The LED turns green if the interface module is receiving power and the
microcontroller is functioning normally.
2. Attach an invalid probe to the TekConnect input:
The LED turns red if the interface module is receiving power, the microcon-
troller is functioning normally, and a probe is being sensed.
If the LEDs respond normally at power on, but no signal is detected by the
sampling oscilloscope (probe connected), check the sampling module and
semi-rigid cable connections.
