SetMeasuringMode
BOOLEAN APIENTRY SetMeasuringMode(
IN HANDLE Handle,
IN ULONG *Mode,
IN int Value )
Members
Mode
The mode in which the frontend should be set
Value
The value which is used by the chosen mode
Return Value
If successful this function returns TRUE, else FALSE. If the
function returns FALSE, use GetErrorCode
to get the error code.
If the returned error code is 1, the frontend can not be set in
the requested mode.
Comments
Most Refa systems support impedance measurement.
During
impedance measurement the device measures the electrode impedance of
each input
channel. This feature is added to switch between these modes of
operation.
Mode | Description | Value |
MEASURE_MODE_NORMAL | Normal mode |
0 |
MEASURE_MODE_IMPEDANCE_EX | Impedance mode |
3 |
Impedance measurement
To put the device in impedance mode, set the Mode parameter
to MEASURE_MODE_IMPEDANCE_EX. In this case the Value parameter is used to select
at which level to LED on the
device should
indicate that the electrode impedance is too high. The Value parameter can
be any of the following values:
Value |
Description | Value |
IC_OHM_002 | Impedance limit at 2 kOhm | 0 |
IC_OHM_005 | Impedance limit at 5 kOhm | 1 |
IC_OHM_010 | Impedance limit at 10 kOhm | 2 |
IC_OHM_020 | Impedance limit at 20 kOhm | 3 |
IC_OHM_050 | Impedance limit at 50 kOhm | 4 |
IC_OHM_100 | Impedance limit at 100 kOhm | 5 |
IC_OHM_200 | Impedance limit at 200 kOhm |

Before calling this function, stop the frontend by calling Stop().
Check the user manual of your
frontend to see if your frontend supports impedance
modes.
Applies to
All frontends that support impedance measurements.
Refer to the manual of your
frontend.
