10-5-7-2 Basic Probe Care
The system user manuals and various probe handling cards provide a complete description of probe 
care, maintenance, cleaning and disinfection. Ensure that you are completely familiar with the proper 
care of GE probes.
Ultrasound probes can be easily damaged by improper handling. See the User Manual and probe care 
cards for more details. Failure to follow these precautions can result in serious injury and equipment 
damage. Failure to properly handle or maintain a probe may also void its warranty.
Any evidence of wear indicates the probe cannot be used.
Do a visual check of the probe pins and system sockets before plugging in a probe.
TEE and Interoperative probes often have special considerations and individual probe user manuals. 
For TEE and Interoperative probes also refer to their separate user manuals.
10-5-7-3 Basic Probe Cleaning
Refer to the User’s Manual for details on probe cleaning.
NOTE: To help protect yourself from blood borne diseases, wear approved disposable gloves. These are made 
of nitrile derived from vegetable starch to prevent allergic latex reactions.
NOTE: Failure to follow the prescribed cleaning or disinfection procedures will void the probe’s 
warranty. DO NOT soak or wipe the lens with any product not listed in the User Manual. Doing 
so could result in irreparable damage to the probe. Follow care instructions that came with the 
probe.
NOTE: Disinfect a defective probe before you return it. Be sure to tag the probe as being disinfected.Table 10-13   Probe Related Checks
StepItemDescription
1 Probe Holder
Clean probe holders (they may need to be soaked to remove excess gel).
2ProbesThoroughly check the system probe connectors and remove dust from inside the connector sockets 
if necessary. Visually check for bent, damaged or missing pins

Using a Phantom
See the Basic User Manual “Customer Maintenance” for information on using a phantom and quality 
assurance tests.
Section 10-7
Electrical Safety Tests
10-7-1 Safety Test Overview
The electrical safety tests in this section are based on and conform to NFPA 99 (For USA) and IEC 
60601-1 Medical Equipment Safety Standards. They are intended for the electrical safety evaluation of 
cord-connected, electrically operated, patient care equipment. If additional information is needed, refer 
to the NFPA 99 (For USA) and IEC 60601-1 documents.
 
Test the system, peripherals and probes for leakage current. Excessive leakage current can cause 
injury or death in sensitive patients. High leakage current can also indicate degradation of insulation and 
a potential for electrical failure. Do not use probes or equipment having excessive leakage current.
To minimize the risk that a probe may shock someone the customer should:
• Not use a probe that is cracked or damaged in any way
.i.Probe Leakage Current, Frequency;
• Check probe leakage current:
* Based on your facilities QA program for surface probes
* Based on your facilities QA program for endocavitary probes
* whenever probe damage is suspected
WARNINGWARNINGTHE USER MUST ENSURE THAT THE SAFETY INSPECTIONS ARE PERFORMED AT 
LEAST EVERY 12 MONTHS ACCORDING TO THE REQUIREMENTS OF THE PATIENT 
SAFETY STANDARD IEC-EN 60601-1. ONLY TRAINED PERSONS ARE ALLOWED TO 
PERFORM THE SAFETY INSPECTIONS MENTIONED ABOVE.
CAUTIONTo avoid electrical shock, the unit under test must not be connected to other electrical 
equipment. Remove all interconnecting cables and wires. The unit under test must not be 
contacted by users or patients while performing these tests.
CAUTIONPossible risk of infection. Do not handle soiled or contaminated probes and other components 
that have been in patient contact. Follow appropriate cleaning and disinfecting procedures 
before handling the equipment.

10-7-2 GEMS Leakage Current Limits
The following limits are summarized for NFPA 99 (For USA) and IEC 60601-1 Medical Equipment 
Safety Standards. These limits are GEMS standards and in some cases are lower than the above 
standards listed.
 
 
NOTE: *Mains Applied refers to the sink leakage test where mains (supply) voltage is applied to the 
part to determine the amount of current that will pass (or sink) to ground if a patient contacted 
mains voltage.
The following tests are performed at the factory and should be performed at the site. These tests are: 
grounding continuity, chassis leakage current, probe leakage current, and ECG leakage current. All 
measurements are made with an electrical safety analyzer Model 600/600E built by Dale Technology 
Corporation or equivalent device. Table 10-14   Chassis Leakage Current Limits—Accessible Metal Surfaces

10-7-3 Outlet Test - Wiring Arrangement - USA & Canada
Test all outlets in the area for proper grounding and wiring arrangement by plugging in the neon outlet 
tester and noting the combination of lights that are illuminated. Any problems found should be reported 
to the hospital immediately and the receptacle should not be used.
The Dale 600 has self-contained lamps designed for testing the outlet wiring arrangement. Plug the 
Dale 600 into each outlet to be tested comparing the lamp status.
NOTE: No outlet tester can detect the condition where the Neutral (grounded supply) conductor and the 
Grounding (protective earth) conductor are reversed. If later tests indicate high leakage currents, this 
should be suspected as a possible cause and the outlet wiring should be visually inspected.Figure 10-1   Typical Outlet Tester

Measure the resistance from the third pin of the attachment plug to the exposed metal parts of the case. 
The ground wire resistance should be less than 0.2 ohms. Reference the procedure in the IEC 601-1.1.
10-7-4-1 Meter Procedure
Follow these steps to test the ground wire resistance.
1.) Turn the LOGIQ™ 9 unit OFF.
2.) Plug the unit into the meter, and the meter into the tested AC wall outlet.
3.) Plug the black chassis cable into the meters “CHASSIS” connector and attach the black chassis 
cable clamp to an exposed metal part of the LOGIQ™ 9 unit.
4.) Set the meters “FUNCTION” switch to the RESISTANCE position.
5.) Set the meters “POLARITY” switch to the OFF (center) position.
6.) Measure and record the ground wire resistance.
