Sampling
Auto sampling mode continuously updates measurements on the display.
When in Manual mode, the instrument will take measurements for the duration 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.
