only when selecting a network B2
Measuring the class-I equipment and class-II equipment
1.
Connect the instrument and the equipment under test.
See "3.3 Connecting equipment under test to the instrument" (p. 36)
2.
Connect a test lead to terminal T2.
3.
Place the tip of the test lead on the jig to measure the leakage current from the jig.
4.
Place all the applied parts of the equipment under test in contact with each other.
5.
Place the tip of the test lead on the applied parts of the equipment under test.
6.
During manual measurement, total patient leakage current (Patient connection - Earth) measure-
ment starts upon return to the measurement screen.
Measurement conditions can be changed during measurement.
See "6.1 Making manual measurements" (p. 79)
During automatic measurements, becomes available upon return to the measurement
screen. Press to start total patient leakage current (Patient connection - Earth) measure-
ment.
Only is available during automatic measurements.
7.
Any measurement result within the allowable value is acceptable.
If a FAIL is produced, the result of the leakage current test is a PASS if the total leakage current
value less the leakage current value for the jig is within the allowable value.
Total patient leakage current measurement
*
(Patient connection - Earth)
The instrument cannot alone measure the leakage current for all applied parts.
The customer will have to find a jig that can bundle the applied parts.
