Instrument Information
• When the instrument is first powered on the battery icon is displayed, the home
screen will then appear and the battery charge status may show almost empty. The
instrument will then make an assessment of the battery charge remaining and
display the actual charge status after a couple of minutes. When the charger is
connect the home screen will display CHARGING, when the battery is fully charged
the instrument will turn itself off. Please note that with the charger connected you
cannot turn off the instrument until unplugged.
• The S F4 has built in battery saving software to facilitate the longest possible use
between charges. The instrument will therefore power down after a period of 10
minutes of inactivity. If the instrument is in a logging mode this will continue
unaffected. In order to wake the instrument press the on/off key – the home screen
will then be displayed. The instrument will also turn off the backlight after a period
of 5 minutes of inactivity – to wake the instrument press the down arrow key.
• It should be noted that whilst in logging mode the instrument set up cannot be
changed, i.e. the logging interval, sensitivity, time/date, upload or delete data
functions will not operate. To change any of these functions press Stop Logging,
change the required parameter and then press start logging to resume.
