8Patient Cable Test
8Tool (M2662-00003)*
This tool is used to short the lead wires together to test lead wire integrity. To test the 
leads, plug all ten lead wire posts into the holes of the tool and print an ECG. If all 
leads print clear, solid flat lines, the lead wires are intact.
8Front End Test
8Tool (M1770-87909)
*
To test the instrument signal path, plug the larger connector into the patient cable 
connector on the front of the cardiograph. Print an ECG. If the front end is operating 
properly, all leads will show clear, solid flat lines with little or no noise.
8Safety Check
The safety check should be done at least once a year, after any repairs or as needed 
according to IEC60601-1 and IEC60601-2-25 safety standards. 
Contact your biomedical department whenever the cardiograph needs a safety, 
functional or performance test. 
*. The tools are shipped along with the cardiograph.
