.SH DESCRIPTION

\fIe1432_set_arm_time_interval\fR sets the time between arm points when
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
this interval until the elapsed time exceeds the measurement time set by
the \fIe1432_set_meas_time_length\fR function.

\fIe1432_get_arm_time_interval\fR returns the current value of the arm
time interval into a memory location pointed to by \fIarm_time_interval\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.

\fIarm_time_interval\fR is the time interval between arm points when
the arm mode is set to \fBE1432_ARM_TIME\fR by the 
\fIe1432_set_arm_mode\fR function.  When not in order tracking mode, the
resolution of time arming points is four milliseconds, limited by the
resolution of the internal timer interrupt. 

For input channels and source channels, this parameter is not used.
.SH "RESET VALUE"
After a reset, the \fIarm_time_interval\fR defaults to 0.1 seconds. 
.SH "RETURN VALUE"
Return 0 if successful, a (negative) error number otherwise.
