LUNCH BREAK
is turned on (see “Updating the Lunch Break Setting (LUNCH
BREAK)” on page 149), the Lunch Break Screen appears. The unit counts down
from 5 seconds at the top of the screen.

To continue accumulating peak and time-weighted average (TWA) readings from
the last time the GX-6000 was used, press and release the POWER/ENTER
button before the countdown reaches 0 or allow the countdown to reach 0. If you
do not press the POWER/ENTER button within the 5 second countdown, the
GX-6000 automatically resumes accumulating the peak and TWA readings. The
GX-6000 will also continue to keep track of operating time including the
operating time from the last time the GX-6000 was used. See “Time in Operation
Screen” on page 54 for more information about how the GX-6000 tracks the
operating time. The short-term exposure limit (STEL) reading is reset each time
the GX-6000 is turned on.
•
To reset the accumulation of these measurements, press and release the DISP/
LOCK button before the countdown reaches 0.
