8. Perform calibration (see also section 2.a).
a. Select menu item „Load Calibration" and follow the load
calibration instructions given in section 2.a.
3. Calibration of the analog input and outputs:
* Connect ergometer to EKG unit with analog load control.
* Select menu item Input 1 Load (outputs 2 to 5 are not used).
3.a Calibration of input for analog load control
* „IN-VOLT indicates the input voltage level.
* Select output for low load setting, i.e.
20 Watt at the ECG unit
and
set OFFSET 20 Watt at the ergometer.
* Confirm setting „OFFSET" with „ENTER" .
* Wait for the displayed voltage to stabilize.
* Confirm current setting, e.g. 20 Watt with „SET".
* The current setting is saved.
Perform the setting for the high load value in the same way.
* Select output for high load setting, i.e.
300 Watt at the EKG unit
and
set GAIN 300 Watt at the ergometer
* Confirm setting „GAIN" with „ENTER". .
* Wait for the displayed voltage to stabilize.
* Confirm current setting, e.g. 300 Watt with „SET".
* The current setting is saved and calibration of the analog load
input is terminated.
OFFSET: range from 20 to 1000 Watts in steps of 10 Watts
GAIN: range from 20 to 1000 Watts in steps of 10 Watts
3.b Calibration of output for analog load
In order to calibrate the analog load output the
ergometer output voltage, e.g. 3000 mV and
the corresponding power value, e.g. 300 Watts
are set at the ergometer. Select requested setting (see 3.a) and
confirm with "SET".
GAIN: range up to 3000 mV in steps of 10 mV
GAIN: range from 20 to 1000 Watts in steps of 10 Watts
Note: The calibration of the analog load output signal can only be
verified, after the Service Menu has been terminated. The analog
output signal can be checked after starting an ergometry test.
