Abstract: | An inexpensive, field-portable event recorder for monitoring insect or other animal behavior is described. The recorder consists of a 16-key event code keyboard and a 99.99-min timer interfaced to a low-cost printing calculator. The event code number and the elapsed time (.01-min resolution) from the start of an observation period are printed whenever an event key is pressed. The recorder is operable over a temperature range of 0°C to 50°C, with a timing error of less than ±.05% of the 99.99-min full-scale timing range. Periods longer than 99.99 min can be monitored, provided the return to zero of the timer is noted and taken into consideration. |
