OPERATION

Insert the probe plugs int o the recept ac les loc ated on the f ront of the therm om et er. The plugs and receptacles are k ey ed w ith small and large pins. M ak e certain t hat the plugs are inserted correct ly , do not f orc e them.

NOTE: Only one probe is required f or norm al operat ion. Press the ON button t o turn the unit on. Press the F/C button to display the temperat ure in Fahrenheit (°F w ill appear on t he

display) or Celsius (°C will appear on the dis play ). Press the T1 button t o display t he temperat ure of probe 1

(T1 appears on the display). Press the T2 button t o display t he temperat ure of probe 2

(T2 appears on the display). Place the probe tip in contac t wit h the material to be m eas ured and read the

temperature on the display.

MAX MODE

In the MAX mode, the therm om et er will display the highest t em perat ure reading achieved. It does not dis play the current temperat ure if it falls below the MAX reading.

Example: In the MAX mode

±0.3% + 1°C

in either Fahrenheit or Cels ius

between probe 1 and probe 2

ROBES

The probes supplied are ultra-fas t res pons e T y pe-K t herm oc ouple nak ed bead probes with 4' leads and teflon insulat i on. Operat ing t em perat ure range f or t hes e thermocouples is or 500°F (260°C ).

An accessory stainless steel tri ple purpos e probe wi t h handle is av ailable. An accessory surfac e probe is als o available (see ac c es s ori es ).

Longer leads and extensions m ay be us ed. T he lead effec t for 164 f eet (50 met ers ) is generally less than 0.2°C w it h a limit of error of 2.2°C. Type-K wire and Type-K connectors mus t be used.

OFFSET ADJUSTMENT (Fine tuning) The offset controls are set at the fact ory to allow for the variations f ound in standard thermocouples. By adjus t ing t he offs et cont rols, f ound below t he thermoc ouple p lugs, you can optimize measurem ent ac c urac y for a part ic ular thermoc ouple (or pair of thermocouples) at a part ic ular t em perat ure.

ADJ

USTING FOR T1 OR T2 MEASUREMENTS

1. Plug in the T 1/ T 2 thermoc ouple and t urn t he t herm om et er ON . Press the appropriate T1/T2 key t o display reading.

2. Place t he t herm oc ouple in a k now n stable t em perat ure env ironm ent at or near the temperature you w is h to meas ure. Allow t he reading t o stabiliz e.

3. Slowly adjus t t he T1/T 2 OFFSET c ont rol that c orres ponds t o the selected input until the thermom et er reading m at c hes the tem perat ure of the k now n environment. (Allow s uf f icient t ime betw een adjus t m ent s to allow for measurement lag).

4. The c alibrat ion of t he thermom et er-t herm oc ouple c om bi nat ion is now opt im iz ed (fine-tuned) for measurem ent near t he t em perat ure us ed in step 2.

ZERO ADJUSTMENT FOR T1-T2 MEAS URE ME NTS :

1. Plug in both t he T 1 and T2 thermocouples.

2. Turn t he t herm om et er on and pres s the T1-T 2 button.

3. Place t he t herm oc ouples in a k now n stable t em perat ure env ironm ent at or near the temperature you w is h to meas ure and allow the reading to s t abiliz e.

4. Slowly adjus t eit her T 1 or T2 (but not both) of the OFF SET controls unt il the thermometer reads " 0". (Allow s uffic ient time bet w een adjus t m ents to allow f or measurement lag).

5. The t herm om et er-thermocouple combination is now s et for different i al temperature measurem ent near t he t em perat ure us ed in s t ep 3.

WRIST STRAP AND STAND

The unit is supplied with a Velcro w rist strap t hat att ac hes through t he t w o slots in the back of the rubberized casing. R em ov e the rubberized c ov er and s lip t he end of the strap through the slots, Velc ro side out, fast en at the buckle.

A bench stand is also supplied wit h t his unit and is part of the rubberiz ed c as e. Loc ate the rectangular opening at the bac k of the unit. Place your fingernail under the opening and flip the stand out. To close t he stand, simply snap it shut.

Select the desired input (T 1, T2 or T 1-T 2) then press the MAX button (MAX w ill appear on the display). The thermom et er w ill dis play the m ax imum t em perat ure reading on the LCD display. Press t he MAX key again t o exit MAX rec ording m ode.

HOLD Press the HOLD key to "freeze" the display at the c urrent T1, T2 or T1-T 2 reading (DH will appear in the display). Press the HOLD k ey again to ret urn t o the current reading.

TEMPERATURE DIF FE RE NTIAL T1-T2 Press the T1-T2 key to display the difference in temperature betw een probe 1 and probe 2. This feature takes the tem perat ure being m eas ured at probe 2 and subt rac ts it from the temperature being m eas ured at probe 1 and dis play s t he differenc e. NOTE: Two probes must be connected to the unit to use this feature.
