LMRT & SMRC: Special Transmitter Options
- (STO-1A) Transmitter pulse rate doubles when no movement
occurs during a preset delay time. Resumption of movement resets pulse
rate to normal operating levels.
(STO-1B) Pulse rate is reduced after a user specified period of inactivity. Resumption of movement resets pulse rate to normal operating levels. NOTE: STO-1A and STO-1B offer user definable delay times.
- Activity Sensor
- (STO-2A) A small mercury tip-switch is installed to indicate
the degree of activity of an animal. Extra pulses are injected as
animal activity increases. Transmitters should be calibrated using
captive animals to determine the relationship between pulse rate and
activity.
(STO-2B) Activity sensing tip-switch transmits one of two different pulse rates depending on orientation of transmitter at any given instant. Transmitter is designed to change pulse rates as it passes through an angle parallel to flat ground (head up - head down).
