Important: The safety analyzer must be located as far away from the magnet as possible to successfully execute this test. Getting closer to the magnet affects the safety analyzer and alters the tool’s ability to take an accurate measurement.
Procedure
Plug the analyzer into a power source which allows access to the rear end of patient table.
At the patient monitor accessory panel, connect the patient lead cable and the cardiac lead set at the ECG connector.
Figure 1. ECG connector
Connect the cardiac leads to the Dale 600/600E (46-328406G1).

Place the Neutral button in the CLOSED position.
Place the Polarity switch in the NORMAL position.
On the Dale 600/600E, set the main selector switch to LEAKAGE - LEAD-GND.
Move the LEAD switch through the positions shown in Table 1. Verify that the leakage current displayed on the meter is less than 50 microamps and record the values on the data sheet.
Note: Typically, the lead-to-ground and lead-to-lead readings are close to zero and less than 50 microamps. Measurements exceeding 50 microamps indicate an issue in the corresponding lead.

On the Dale 600/600E, set the main selector switch to LEAKAGE - LEAD-LEAD.
Move LEAD switch through the positions shown in Table 1. Verify that the leakage current displayed on the meter is less than 50 microamps and record the values on the data sheet.
On the Dale 600/600E, set the main selector switch to LEAKAGE - LEAD-ISO.
Make sure that the leads are not touching the floor.
Move the LEAD switch to ALL LEADS.
Press ISO TEST and record the meter reading on the data sheet. This reading must be less than 50 microamps.
Repeat steps Step 6 - Step 13 with the POLARITY switch in the REVERSED position.
