7.1.1

Warranty Information

Only authorized ergoline service partners are allowed to carry out maintenance. Improper repair of 
the device may render any existing warranty null and void.

7.2 Functional Test

Functional tests can only be performed in conjunction with the application software. We recom-
mend performing the following functional tests within the application software. For information 
on possible functional restrictions (e.g., alarms), refer to the instructions for use of your applica-
tion software and contact the manufacturer.

FT1.1 Verify HR reading in the software:
• Switch on the 1-channel transmitter.
• Connect a calibrated ECG signal generator via the adapter.
• Add a test patient in the software and assign this patient to a training place.

FT1.2 Verify HR alarms in the software [A = HR

max

, B = HR

min

, C = HR

zero

]:

• Switch on the 1-channel transmitter.
• Connect a calibrated ECG signal generator via the adapter.
• Add a test patient in the software, set the heart rate limits, and assign this patient to a training 

place.

FT1.3 Low battery check:
• Insert an almost depleted battery in the 1-channel transmitter
• Switch on the 1-channel transmitter.

FT1.4 Full battery check:
• Insert a fully charged battery in the 1-channel transmitter.
• Switch on the 1-channel transmitter.

FT1.5 Check wireless ECG signal transmission:
• Switch on the 1-channel transmitter.

Test ID

Description

FT1.1:

Generate an ECG signal with a defined heart rate. Check the heart rate displayed 
in the software.
Expected result: The HR displayed in the software corresponds to the generated 
heart rate.

FT1.2_A

Generate an ECG signal with a heart rate above the upper heart rate limit. 
Expected result: The software indicates the violation of the upper HR limit.

FT1.2_B

Generate an ECG signal with a heart rate below the lower heart rate limit.
Expected result: The software indicates the violation of the lower HR limit.

FT1.2_C

Switch off the ECG signal.
Expected result: The software indicates HR = zero.

FT1.3

Connect the 1-channel transmitter to the software.
Expected result: Once the 1-channel transmitter is connected, a charging icon 
appears in the software. For charge levels below 40 % the icon is red.
