A test system timer has been designed for measuring multiple time phases or sequences of each of multiple test samples or points simultaneously. The timer contains multiple internal clocks and a countdown time display area. Upon activation of the timer, an entire sequence of multiple phases for the test sample is initiated. The timer has visuals to permit the user to know how many test samples have been collected, which phase of a timing cycle the test sample is in, the amount of time remaining in any given phase, and alarms to alert the operator to action as needed. In addition, the timer base has a retainer plate to securely hold a test sample carrier or associated equipment. |
