.SH DESCRIPTION

\fIe1432_set_meas_time_length\fR sets the length of time a measurement will
run in the time arming mode. It is a global parameter applying to all channels
in a single module.  Once started, a measurement will arm at multiples of
the time interval set by the \fIe1432_set_meas_time_length\fR function until 
the elapsed time exceeds this measurement time length.

\fIe1432_get_meas_time_length\fR returns the current value of the measurement
time length into a memory location pointed to by \fImeas_time_length\fR.

\fIhw\fR must be the result of a successful call to
\fIe1432_assign_channel_numbers\fR, and specifies the group of
hardware to talk to.

\fIID\fR is either the ID of a group of tach channels that was obtained
with a call to \fIe1432_create_channel_group\fR, or the ID of a single
channel.

\fImeas_time_length\fR is the total measurement time length when
the arm mode is set to \fBE1432_ARM_TIME\fR by the 
\fIe1432_set_arm_mode\fR function. 

For input channels and source channels, this parameter is not used.
.SH "RESET VALUE"
After a reset, the \fImeas_time_length\fR defaults to 30.0 seconds. 
.SH "RETURN VALUE"
Return 0 if successful, a (negative) error number otherwise.
