10-7-6-3Dale 600 Meter Procedure (cont'd)
7.) Record the patient lead to ground leakage current measured on the data sheet.
8.) Set the meter's "FUNCTION" switch to LEAD TO LEAD position to measure the lead to lead leakage
current.
9.) Select and test each ECG lead positions (except ALL) of the LEAD selector, testing each to the
power condition combinations.
10.)Record the lead to lead leakage current measured on the data sheet.
11.)Set the meter's "FUNCTION" switch to LEAD ISO position to measure the patient lead isolation
current.
12.)Select and test each ECG lead positions (except ALL) of the LEAD selector, testing each to the
power condition combinations.
13.)Depress the rocker switch to ISO TEST and read the isolation current. To apply the voltage to the
lead safely, the voltage is only applied when the rocker switch is depressed to ISO TEST.
14.)Record the patient lead isolation current measured on the data sheet.
10-7-7 Isolated Patient Lead (Source) Leakage–Lead to Lead
Reference the procedure in the IEC 60601-1. When using the Dale 600, switch the meter's function
selector to the LEAD-LEAD position. Select and test each of the five ECG lead positions (except ALL)
on the LEAD selector, testing each to the power condition combinations found in the table. Record the
highest leakage current measured.

1.) Closed Normal
2.) Open Normal
3.) Closed Reversed
4.) Open Reversed
10-7-8 Isolated Patient Lead (Sink) Leakage-Isolation Test
Reference the procedure in the IEC 60601-1. When using the Dale 600, switch the meter's function
selector to the LEAD-ISO. Select the ALL position on the lead selector. Depress the rocker switch to
ISO TEST to test lead isolation.
Line voltage is applied to the ECG leads during this test. To avoid possible electric shock
CAUTION
hazard, the system being tested must not be touched by patients, users or anyone while the ISO
TEST switch is depressed.
NOTE: It is not necessary to test each lead individually or power condition combinations as required in
previous tests.
