In order to get precise test data, it is absolute necessary that the SRM – High Performance Ergometer is calibrated. We recommend conducting this calibration before every measurement.
Ergometer Settings
Reading slope and serial number
Contents
PowerMeter Slope
The slope in the ergometer software must be correspond to the slope of the PowerMeter and the PowerControl. We recommend to verify and control the slope of the PowerMeter before every test day. You can find the correct PowerMeter slope on small labels located-at
- the rear of the PowerMeter,
- the front of the ergometer,
- the right crankarm,
- the handlebar.

Zero Offset
The PowerMeter delivers a certain frequency which is proportional to the torque of the pedal force on the crank. If there is no load on the crank, the PowerMeter is sending a base frequency which must be communicated to the ergometer software and to the PowerControl as a reference value. This procedure is called zero offset calibration (offset adjustment).
The zero offset calibration has to be done before every new assembly of the PowerMeter and also before every measurement resp. every training on the Ergometer. A wrong zero offset calibration can result in an internal miscalculation of the power.
Please perform the zero offset calibration as it is described below:
- For a manual comparison, please turn the right unloaded crank clockwise to activate the PowerMeter.
- Wait a few seconds until the displayed value is stabilized.
- By pressing the Read Settings button, the zero offset will be displayed in the white background field.
- Press the Write Settings button, so that the zero offset will be saved.

Circumference
The circumference only influence the displayed speed and is not important for the calculation of the data. We recommend to insert a value of 1.000 mm.
The following points show the current state of the ergometer. They are important for the identification and the service.
Firmware
The firmware can be updated if you drop the latest “SRM Firmware Image” file (*.sfi) in the box on the lower left corner of the screen: Drop file here to import. The current firmware incl. date is displayed (e.g. V 1.0.8, 20.06.2016).

Read the current settings of the ergometer incl. the zero offset and the Slope.
Write Settings
Here it is possible to insert the slope and to save/to write it for the correct data. Please note that the must be correspond to the slope of the PowerMeter.
