Using Ansur with the ESA612 and the 1210 adapter

Using Ansur with the ESA612 and the 1210 adapter
Introduction
The 1210 Adapter Box Assembly has been designed to increase the number of lead or
applied parts connections to the ESA612 Electrical Safety Analyzer from 5 to 14. The
adapter itself ties up to ten leads together into a single lead that is plugged into one of
the input jacks of the analyzer. The four remaining analyzer input jacks can also be
used in conjunction with the adapter.
This application note explains how to set up a patient lead configuration using this
adapter.
The principle of the adapter is that it tethers all leads on the adapter to a single input on
the ESA612 and appears as a single lead measurement in Ansur.
Example 1
Physical connections
Figure 1 shows one application of the adapter. The defibrillator/monitor in the example
has ten ECG leads, two pacer leads, and two defibrillator paddles which need to be
tested together, and in groups of single function, for current leakage per IEC62353.

The example shows the ECG leads to be snap-type connectors and two BJ2ECG
adapters are shown plugged into the adapter. If the ECG leads did not have snap
connectors, then the Universal Snap to Banana Adapter can be used to make the
connections to the adapter. The common lead from the adapter is plugged into the RA
jack (1st jack) of the analyzer. Using four sheathed test leads with alligator clips,
connect the two defibrillator paddles into the RL and V1 analyzer jacks and the two
pacer leads into the LL and LA jacks. Using the selection that ties all five analyzer
jacks together will test all fourteen leads for leakage current. Using the selection of
applied part group of 1, 2, and 2 allows for testing of groups of applied parts of single
function.
Ansur configuration
For the set-up above, we must define three patient lead groups/modules for the autosequence. This is done in the Module Setup tab in the Test Guide.

ECG leads
The first module we define will be one lead for the 12-lead ECG. The ECG leads will
appear as one single lead connected to the RA input since they are tethered on the 1210
adapter, and the single lead from the 1210 adapter is connected to the RA input on the
ESA612.
Paddles
The second group is the Paddles. They are defined as a normal module with two leads,
occupying the LL and LA inputs on the ESA612.
Pacer
The last module is for the two leads for the Pacer. They are also defined as a normal
module with two leads, occupying the RL and V1 leads.
The complete Module Setup configuration in Ansur should then look like this:

Summary
As described in this application note, the 1210 adapter allows the user to expand the
number of leads or applied part connections to the ESA612 Electrical Safety Analyzer
from 5 to 14 when required. The 5 integrated input jacks on the Analyzer allow for
common lead/applied part connections while keeping the Analyzer portable and easy to
carry. The adapter gives the user the flexibility to test more than 5 leads or applied parts
when required. The Ansur automation allows for automated tested for easy and speedy
testing and documentation. If you have any questions or comments about the
