CONNECTING AN RTD
Usethe correct 100ohm RTD(alpha= 0.003850)
for your instrument.Using an incorrect probe type
will result in erroneous readings. Insert the 3-pin
plug into the mating connector on the top of the
instrument.

fective,the displaywillindicate“oPEn”.
3. Select °C or °F by pressing the °C/°F key.Tem-
peraturescalecanbeswitchedatanytime.The
thermometer retains thelastselected scale the
next time you turn the power on.
4. For optimum instrument accuracy, allow one
minute for ambient temperature stabilization.If
theunit has beenstoredat an extremeambient
condition,moretime will beneeded.
When taking temperature measurements, allow
timeforthereadingto stabilize.Multiplyingthetime
constant of the probe by 5 will give you the ap-
proximatetimerequired.
If desired, press the HOLD key to retain the read-
ing on the display.Press HOLD key again for nor-
maloperation.
The display will show “Ur”(under range) or “Or”
(over range) if the temperature reading is out of
rangeoftheinstrument.
OPERATION
1. Press the ON/OFF key.The thermometer per-
forms a self-test and all display digits and indi-
cators, as shown below, should remain on for
