ZmSetFrequency

Function

Set the measurement frequency.

Ret = ZmSetFrequency ( Id , ChannelNo , Frequency )

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

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

Frequency [ VB.NET： UShort ] [ C, C++： unsigned short ] [ C#： ushort ]
Specify the measurement frequency.

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

Definition	Value [Dec]	Description
ZM_ERR_SUCCESS	0	Normality completion
ZM_ERR_SYS_CHANNEL_NO	20100	Channel No is out of the settable range.
ZM_ERR_SYS_FREQUENCY	20101	Frequency is out of the settable range.

Set the measurement frequency.
The measurement frequency can be set for each channel.

Set the measurement frequency to "0 : Frequency 120Hz" for ChannelNo = 1.

VB.NET	Dim Ret As Integer Ret = ZmSetFrequency ( Id , 1 , 0 )
C, C++	long Ret; Ret = ZmSetFrequency ( Id , 1 , 0 );
C#	int Ret; Ret = zm.SetFrequency ( Id , 1 , 0 );
