recommend that you always install a fresh battery before logging
critical data.
If INSTANT was selected in the SETUP window, the RHDL50 begins logging
at the instant the SETUP button is pressed. If MANUAL was selected, the
RHDL50 must be manually started by pressing and holding the device’s
yellow button for approx. 3 seconds, or until the two LEDs on the RHDL50
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 or yellow LED
flashes when user programmed alarm limits are exceeded. For details, see
LED status guide.
