INSTRUMENT OPERATION - Switch the instrument on and
apply the tip of the probe to the substance or medium being
measured. The sensor is located at the tip of the probe,
therefore the minimum depth insertion should be 0.12"
(3mm).
AUTO-OFF - The unit will automatically turn off after 10
minutes to maximize the battery life. This function can
be disabled. To disable the auto-off function, switch the
unit off, then press and hold the HOLD/LOCK and ON/OFF
buttons at the same time - 'auto-off disabled' will scroll
across the screen. Once the unit is switched off it will
revert to the auto-off function being enabled.
ROTATIONAL DISPLAY - The unit’s display will rotate
through 90° with each turn so that it can be used at any
angle or in either hand. This function can be disabled.
Press and hold the LOCK button for 3 seconds to lock the
orientation of the display, 'Loc on' will be displayed. To
enable this function, repeat as before and 'Loc oFF' will be
displayed.
SMART BACKLIGHT - The unit incorporates a smart
backlight which automatically switches on when the unit
is being used in low-light conditions. The backlight will
activate for 10 seconds. Please note the light sensor is
incorporated in the 'o' in the Smart Thermometer label.
MAX/MIN - Press the MAX/MIN button to display the
values. The instrument retains the max/min values when
switched off. To reset, press the MAX/MIN button for three
seconds, 'rst' will be displayed. Please note while in the
MAX/MIN mode, the instrument will continue to measure.
HOLD - Press the HOLD button to retain the last
temperature measured, 'HOLD' will be displayed. To
continue to measure, press the HOLD button again.
C/F - With the unit switched off, press and hold the ON/OFF
button for 5 seconds to change between °C and °F. Once
changed, the unit will remain in the selected value.
BATTERY REPLACEMENT - The low battery symbol will
indicate when the batteries need replacing. The instrument
continues to measure accurately, but we recommend that
the batteries are changed as soon as possible. To replace
the batteries, remove the battery cover on the bottom using
a screwdriver. Replace the AAA batteries ensuring that
polarity is correct. Replace the cover and tighten to ensure
the unit remains waterproof. The cover can only be fitted
one way.
Please note: If the batteries are removed, modes set such
as Lock and Max/Min will be reset to the default setting.
INSTRUMENT CLEANING - Clean the instrument regularly
with an anti-bacterial probe wipe to avoid potential food-
borne bacteria growth.
WARNING - IPA and other solvents may cause damage to
the case and screen of this instrument.
