DIRECTION 5394227, 12 LOGIQ S8/LOGIQ E8 SERVICE MANUAL
Section 9-8 - Electrical Safety Tests 9 - 29
9-8-10-1 Generic Procedure on Probe Leakage Current (cont’d)
Figure 9-11 Test set with meter
NOTE: Each probe will have some amount of leakage current, dependent on its design. Small variations in
probe leakage currents are normal from probe to probe. Other variations will result from differences in
line voltage and test lead placement.
The ultrasound probe’s imaging area is immersed in the Saline solution along with a grounding probe
from the test meter to complete the current path.
NOTE: The Saline solution is a mixture of water and salt. The salt adds free ions to the water, making
it conductive. Normal saline solution is 0.9% salt and 99.1% water. If ready-mixed saline
solution is not available, a mixture of 1 quart or 1 liter water with 9 or more grams of table salt,
mixed thoroughly, will substitute..
Figure 9-12 FibroScan probe with Aluminium foil
CAUTION
To avoid probe damage and possible electric shock, do not immerse probes into any liquid
beyond the level indicated in the probe users manual. Do not touch the probe, conductive liquid
or any part of the unit under test while doing the test.
CAUTION
FibroScan probe does not have resistance to water. DO NOT immerse FibroScan probe into any
liquid, and use Aluminium foil instead of saline as below.
