Operating Instructions

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 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 turn off
automatically after 20 seconds to preserve battery life.
SENSORS - This instrument should only be used with
type K (Nickel Chromium/Nickel Aluminium) thermocouple
probes (to BS EN 60584-2) fitted with miniature type K
thermocouple plugs, where applicable (to BS EN 50212).
BATTERY REPLACEMENT - The instrument will display
'LO BAT' 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 batteries with three AAA batteries
located under the rear cover that is held in place by a single
screw.

FR - UTILISATION DE L'INSTRUMENT - Si besoin est,
connectez une sonde par l'intermédiaire de la douille située
en haut de l'instrument. Allumez l'instrument et appliquez
la pointe de la sonde à la substance ou au milieu à mesurer.
La stabilisation de l'indication de l'instrument peut prendre
quelques secondes, en fonction de la nature de la mesure
et de la sensibilité de la sonde.
HOLD (Therma K-Plus) - Maintenez le bouton HOLD/°C/°F
enfoncé pour geler l'affichage.
EXTINCTION AUTOMATIQUE (Therma K-Plus) -
L'instrument s'éteindra automatiquement après 10
minutes. Pour désactiver l'extinction automatique (Therma
K-Plus), enfoncez le bouton BACKLIGHT tout en allumant
l'instrument (la réactivation a lieu lorsque l'on éteint
l'instrument).
CHANGER DE FAHRENHEIT EN CELSIUS - Maintenez
la touche "ON / OFF" (Therma K-Plus: HOLD) pendant 5
secondes et la température affichée va changer entre °F et
°C.
CIRCUIT OUVERT/SONDE DEFECTUEUSE - Si la sonde a
développé un défaut 'Circuit Ouvert', l'instrument affichera
'Err'.
CAPTEURS - Cet appareil ne doit être utilisé qu'avec des
sondes à thermocouple (nickel-chrome/nickel aluminium)
de modèle K (conformément à la norme EN 60584-2)
dotées de prises miniatures à thermocouple de type K, le
cas échéant (conformément à la norme BS EN 50212).
RÉTRO-ÉCLAIRAGE (Therma K-Plus) - Appuyez sur la
touche rétro-éclairage et l'affichage s'allume. Appuyez à
nouveau et le rétro-éclairage s'éteint. Le rétro-éclairage
s'éteint automatiquement après 20 secondes pour préserver
la vie de la batterie.
REMPLACEMENT DES PILES - L'instrument affichera
'LO BAT' (piles faibles) pour avertir que les piles auront
besoin d'être changées bientôt. L'instrument continue de
mesurer avec précision mais, après avoir encore été utilisé,
l'instrument affichera 'flat bat' (piles à plat) et s'éteindra.
Remplacez les piles par trois piles AAA situées sous le
couvercle arrière qui est maintenu en place par une seule
