Sampling
Auto sampling mode continuously updates measurements on the display
(
Figure 20
).
When in Manual mode, the instrument will take measurements for the du-
ration of the user-defined Sample Period (in seconds) then “lock” or hold
the readings on the display. The default sample period is 50 seconds, and
can be adjusted from 15 to 60 seconds. Manual mode helps conserve
battery power.
Once the measurements are locked, push the
ENTER
key to log the held
data, or the
Esc
key and then the
ENTER
key to take a new measurement.
NOTE:
When both Continuous Logging Mode and Manual
Sampling mode are enabled, the handheld will power the
sensors on and take measurements for 15 seconds before
logging a data set.

Auto-Shutoff
To conserve battery power, auto-shutoff powers off the instrument after
a user-defined time period (in minutes). The auto-shutoff time can be
adjusted from 1 to 255 minutes. Set to 0 (zero) to disable Auto-Shutoff.

Backlight
In Automatic mode, the instrument display will dim 60 seconds after the
last key was pushed. Once any key is pushed, the instrument display will
return to the user-defined brightness setting and the keypad backlight
will turn on. The screen will dim and the keypad backlight will turn off
after another 60 seconds of inactivity.
In manual mode, the instrument display remains at the user-defined
brightness and the keypad backlight is turned on and off by the Backlight
key. Setting the backlight to manual mode is recommended for bright
conditions.
