BIOMEDICAL EQUIPMENT TROUBLE SHOOTING GUIDE

By Ask Biomedical

BIOMEDICAL EQUIPMENT TROUBLE SHOOTING GUIDE:


1. Establish when the problem occurs
Does the problem appear only under certain
conditions? 
Were there any noises, odors, or other unusual symptoms?

2. Isolate the problem area
To do this, make some simple tests and observations;
then, eliminate the systems that are working properly. 
Check for obvious problems such as broken wires, dirty connections, and split or disconnected vacuum hoses.
ALWAYS check the obvious before assuming something complicated is the cause.

3. Test for problems systematically to determine the cause once the problem area is
isolated.
 Are all the components functioning properly? 
Is there power going toelectrical switches and motors? 
Is there vacuum at vacuum switches and/oractuators?
 Is there a mechanical problem such as bent linkage or loose mounting
screws? 
Performing careful, systematic checks will often turn up most causes on
the first inspection without wasting time checking components that have little or
no relationship to the problem.

4. Test all repairs after the work is done to make sure that the problem is fixed
Some causes can be traced to more than one component, so a careful verification of
repair work is important to pick up additional malfunctions that may cause a
problem to reappear or a different problem to arise.
 A blown fuse, for example, is a simple problem that may require more than another fuse to repair. If you don't look for a problem that caused a fuse to blow, for example, a shorted wire may go
undetected.


MAIN CONCERN

The effective & efficient working condition of a certain 
laboratory equipment depends on the following four 
features:

•Maintenance
•Servicing
•Troubleshooting
•Repair


MAINTENANCE
•Maintenance is a continuous process.
•Must include both the Hardware and the Software.
Hardware:
•Cleaning/Dusting
•Maintaining prescribe levels of parameters such 
as electrical, environmental, and others.
Software:
•Reinstallation/Uninstallation
•Upgrade


SERVICING
•Mainly associated with the hardware parts of the 
equipment.
•It Includes:
•Check-ups,
•Repairs, and
•Updating of all physical components

SERVICING
STEPS:
1. Uninstall all physical components starting from power 
connections.
2. Clean dust from the components.
3. Perform a visual check or electronic check as required.
4. Reinstall all components carefully and properly.
5. Check for loose wiring or crack cables.
6. Check if any jumper is missing, if required replace it 
with a new one.
7. Check for physical damages of peripherals and 
replace them if needed.
8. Tighten all internal and external connections.
9. Switch on the power supply and observe.


TROUBLESHOOTING
•Detection and rectification of faults in the equipment.

Repairing means to rectify the problem in the hardware or 
software.
It is an essential part of troubleshooting. 

Repairing may also include replacement of a component.
