Note: to increase the battery life, the instrument automatically switches off after
5 minutes of stand by operation. However the last recorded value is not lost; to
retrieve it, go back to Paragraph 2 and follow the instructions. After the internal
auto check cycle, the display will show the last measured value.
To intentionally shut the instrument off, keep the
ON/Zero
button pushed until
the LCD shuts off (this takes approximately 4 seconds).

(this step takes approximately 7 seconds). At this
point release the button and the instrument is ready for a new measurement.. The
displayed value is the last recorded power measurement carried out at this
wavelength setting.
