1 General preparation
•Power-on spiroergometry (30min before
beginning of test)
•Power-on ergometer’s power supply
•Preparation diagnostic devices (Lactate
analysis, etc.) 30min beginning of test
•Room temperature (18 –24°C) should
measured
•Relative air humidity should measure (30 –
60%) in room
•Check position of ventilator
2 Settings USB/Serial Converter
The installation of the of USB/Serial Converter
is mandatory for the data recording
Check the activation of the USB/Serial
Converter at the Active port ("SRM
Downloadcable USB")
We recommend the use of the following
USB/Serial Converter:
ATEN USB-to-Serial-(RS 232)Converter,
(Model: UC-232A), (Windows 7)

Interval of storage: 1 second
Slope of Powermeter: see ,,Verify Slop”
(page 5)
Circumference of tire: 1000 mm

Verify slope (Slope of PowerMeter)
Verify the slope before every test-day.
The slope in the PowerControl and in the
SRMWin-Software should correspond to the slope
of the PowerMeter.
You can find the correct PowerMeter slope
located-at:
1. little sticker at the rear of the PowerMeter
2. on the handlebar or on the front of the
ergometer

Verify Zero Offset
Push, simultaneously,
MODE and SET to
switch the
PowerMeter’s display
to calibration mode
For a manual
comparison turn the
unloaded crank in a
clockwise direction to
switch the PowerMeter
on.
Wait a few seconds
until the value
stabilizes on the right
side of the display.
Press SET to apply
the Zero Offset.
(MANU) Value of Pro
will be taken
automatically and is
important for the
measurement.

5 Client / Test person
•Welcoming
•Clients prepare for test - put on the
heartrate strap
•Documentation of personal data of client
(height, weight, etc.)
•Completion questionnaire / exclusion of
liability

6 Settings SRM - Ergometer
•Verify gear (gear 9 red point
corresponding)
•Mount client’s pedals
•Crank length set-up:
Recommendation: if possible use same
crank length as on client’s bicycle
Please consider maximum torque of the
crank 10Nm

Bike fitting: transfer settings of client’s own
bike to the sitting position
Saddle height
The heel with the
extended leg
should reach the
lowest position in
the pedaling cycle.
Saddle setback
In the horizontal
position of the
crank the knee
(patella) should be
perpendicular to
the pedals axle.

a low workload (e.g. 75-100W)
predefined warm-up
•Check the correct settings for:
-Heartrate
-Cadence
-Power
-Speed

8 Setup of test protocol
•Determine the test protocol
SRM –ergometer - software: Options -
Mode
Start Test by: Start Button or cadence
Ergometer Mode: Predefined File

10 End of the test
•Stop the test
SRM - ergometer - software: hit “Brake is
on” button (continous recording of the
heartrate - client can continue pedaling
without resistance and cool down)
or
SRM –ergometer - software: End Button
Comment: entry file name then press Save
