Operating Instructions

INSTRUMENT OPERATION - Connect probes via
the socket located at the top of the instrument.
(The Therma Waterproof uses a miniature type T
thermocouple connector). 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 - Press the HOLD button to stop
measurements and freeze the display temporarily,
press again to continue measuring.

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

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

SENSORS - Therma Waterproof should only be used
with a type T (copper/constantan) thermocouple
probe (BS EN 60584-2) fitted with a miniature
type T thermocouple plug (to BS EN 50212).
This instrument is designed to be compatible with
ThermoWorks manufactured probes.

BATTERY REPLACEMENT - The instrument will
display a low battery symbol to warn that the
batteries will need changing soon. The instrument
continues to measure accurately but after further
usage the instrument will display 'flat bat' and
shutdown. Replace the three AAA batteries located
under the rear case half that is held in place by six
screws. Check the seal for damage and carefully
replace the rear case half, re-fit and tighten the
screws.

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.

BACKLIGHT - Press the HOLD button for two
seconds. Please Note: the backlight will not
operate if the low battery symbol is being displayed.
(Backlight timeout = 20 seconds).

CALIBRATION TRIM - Press the MAX/MIN and
ON/OFF buttons at start-up for five seconds to
enter ('Offset' is displayed). MAX/MIN then cycles
(continuous loop) the trim value in 0.1 steps up to
±2.0ºC (3.6ºF). Press ON/OFF to save the value and
exit Trim mode. (Instrument should not require trim

adjustment. Should only be performed by qualified
person with appropriate calibration standards.)

CHANGE FROM FAHRENHEIT TO CELSIUS - Press
and hold ON/OFF button for five seconds at start-up.
