LOGGING READINGS

If INSTANT was selected in the SETUP window, the Logger begins logging at the instant the SETUP button is

pressed. If MANUAL was selected, the Logger must be manually started by pressing and holding the Logger’s

yellow button for approx. 3 seconds or until the two LEDs on the Logger flash at the same time.

Logging will continue at the programmed sample rate until the number of readings (sample points) specified in the

Setup window is reached.

The green LED flashes once per sample point and the red LED flashes when user programmed alarm limits are

exceeded. The yellow LED will flash at 10 second intervals AFTER the pre-determined number of readings has

been logged.
