Patient Leakage Current Lead-to-Ground Test
“µA” – AC/DC, OE, ON, RM, OERM, ONRM
This test measures the current, in microamps, from
the patient leads to Ground. To display the result
of all leads in parallel to Ground, press the
lead to GND button below the patient leakage current label. To display the
leakage of an individual patient lead to Ground, repeatedly press the lead to GND
button to cycle through the lead selections (1-10).
⇒ Warning! When testing units that have a large inductive load (motor),
always turn OFF the DUT BEFORE reversing Mains.
Patient Leakage Current Lead-to-Lead Test –
“µA” – AC/DC, OE, ON, RM, OERM, ONRM
This test measures the current, in microamps, from
the selected patient lead to all other patient leads in
parallel. To select and display the leakage of an individual patient lead to all other
leads in parallel, repeatedly press the lead to lead button below the patient
leakage current label to cycle through the lead selections (1-10).
⇒ Warning! When testing units that have a large inductive load (motor),
always turn OFF the DUT BEFORE reversing Mains.
Mains on Applied Part Test
“µA”
– RM
This test measures the current, in microamps,
from the patient leads to Ground when the patient
leads are excited by 110% of mains voltage. To execute the test, press and hold the
lead ISO button. The test will stop when the lead ISO button is released.
⇒ Warning! When testing units that have a large inductive load (motor),
always turn OFF the DUT BEFORE reversing Mains.
