Terminals of P1, P2 and P6
According to the test circuits in all three standards, terminals P1, P2 and P6 are defined.
However, in some of the tests it is unclear if unused electrodes should be connected to
terminal P2 or P6. IEC 60601-2-25, Clause 201.12.4.103 (Input impedance) provides an
example case. At first the test states that:
Compliance is checked using the test circuit of Figure 201.106
In that figure, it clearly states that terminals P1 and P2 are for LEAD WIRES, while P6 is
intended only for the NEUTRAL ELECTRODE, or RL/N.
However, the test then goes on to say:
Connect the sine wave signal generator to any tested LEAD (P1 and P2) with
all other LEAD WIRES connected to the N (RL) LEAD WIRE (P6)
The interpretation here is complicated as a “LEAD” refers to the displayed ECG waveform,
not specific electrodes. Using Table 201.106, we can infer that for example, “LEAD V1”
involves V1, RA, LA, LL, but not V2
–
V6. The interpretation could be then that V1 should be
connected to P1, with RA, LA and LL to P2, and V2-V6 are connected to terminal P6 along
with RL/N. A more reasonable interpretation would be to follow the diagram and test each
LEAD wire in turn (first RA, then LA, LL, V1 etc) with all unused LEAD wires connected to P2.

Software Development Kit (SDK)
WhaleTeq provides Windows SDK (Software Development Kit) for SECG 5.0 AIO test system.
All test parameters correspond to specific SDK commands and DLL (Dynamic-link library)
shared library can be used for efficient program binding and version upgrade. Support C/C++
header, C# interface, third party tools and script language integration such as Python.

Calibration and Validation
Both WHALETEQ SECG5.0 AIO and software have been system verified, and reports can be
provided according to your needs.
Prior to shipping, each unit is tested for component values and output voltages, using a
calibrated precision multi-meter. As WhaleTeq cannot provide ISO 17025 accredited
calibration, laboratories which are required to follow ISO 17025 should perform calibration
either periodically or on a before use basis, following normal procedures and practice. The
extent of calibration may be limited depending on the needs of the laboratory.
