INSTRUMENT OPERATION - Where applicable,
connect a probe via the socket located at the top of
the instrument. Switch the instrument on and apply
the tip of the probe to the substance or medium to be
measured. The instrument reading may take a few
seconds to stabilize, depending on the nature of the
measurement and sensitivity of the probe.

HOLD (Therma K-Plus) - Press the HOLD/°C/°F
button to freeze the display.

AUTO OFF - The instrument will switch off
automatically after 10 minutes. To disable auto off
(Therma K-Plus) press down the BACKLIGHT button
while switching on the instrument (this is reset when
the instrument is switched off).

CHANGE FROM FAHRENHEIT TO CELSIUS - Press
and hold the “ON/OFF” (Therma K-Plus: HOLD)
button for 5 seconds at startup and the displayed
temperature will change from °F and °C.

OPEN CIRCUIT/FAULTY PROBE - If the probe has
developed an 'Open Circuit' fault the instrument will
display 'Err'.

BACKLIGHT (Therma K-Plus) - Press the backlight
button and the display will illuminate. Press again
and the backlight will turn off. The backlight will
