ZmGetLevel

Function

Get the measurement signal level.

Format

Ret = ZmGetLevel ( Id , ChannelNo , Level )

Parameters

Id [ VB.NET： Short ] [ C, C++： short ] [ C#： short ] [ Python： ctypes.c_short ]
Specify the device ID retrieved from ZmInit.

ChannelNo [ VB.NET： UShort ] [ C, C++： unsigned short ] [ C#： ushort ] [ Python： ctypes.c_ushort ]
Specify the channel number.

Level [ VB.NET： UShort ] [ C, C++： unsigned short * ] [ C#： out ushort ] [ Python： ctypes.POINTER(ctypes.c_ushort) ]
Specify the variable address for storing the measurement signal level.

Return Value

Ret [ VB.NET： Integer ] [ C, C++： long ] [ C#： int ] [ Python： ctypes.c_long ]

Definition	Value [Dec]	Description
ZM_ERR_SUCCESS	0	Normality completion
ZM_ERR_SYS_CHANNEL_NO	20100	Channel No is out of the settable range.

The others (See also: Details of Error Code)

Initial Value

0 : 500[mV]

Remarks

Get the measurement signal level.
The measurement signal level is gotten for each channel.

Example

Get the measurement signal level for ChannelNo = 1.

VB.NET	Dim Ret As Integer Dim Level As UShort Ret = ZmGetLevel ( Id , 1 , Level )
C, C++	long Ret; unsigned short Level; Ret = ZmGetLevel ( Id , 1 , &Level );
C#	int Ret; ushort Level; Ret = zm.GetLevel ( Id , 1 , out Level );
Python	Ret = ctypes.c_long() Level = ctypes.c_ushort() Ret.value = czm.ZmGetLevel ( Id , 1 , ctypes.byref(Level) )
