range of –200 to 1210 °C (–328 to 2210°F).
The instrument is designed for easy oper ation and
includes the follo wing features:
• Operator selection of temperature scale
• Resolution of 0.01° from –50.00°C to 99.99°C
(–58.00°F to 99.99°F)
• LCD with three four-digit displa ys
• 3-pin circular connector input (mate to Switchcraft
T A3F plug)
• Hold feature f or temporarily retaining a reading
• T w o-point field calibration capability
• Low battery warning
• Stores or logs up to 1000 readings with real-time
markers

DANGER

7
If battery indicator turns on, battery life is
approximately 8 to 10 hours. The battery indicator
will start blinking with less than 1 hour of life
remaining.
AT THIS POINT , BATTERY MUST BE CHANGED .
IF BA TTERY VOL TAGE GOES TOO LOW, DISPLAY
WILL GO BLANK.
See SPECIFICATIONS for battery type.
1. Before changing battery , turn instrument off and
disconnect probe.
2. Loosen screw and lift battery cov er off back of
case.
3. Remov e the two AA batteries.
4. Insert two new batteries, observing polarity .
5. Install cov er and tighten screw .
AC ADAPTER
An optional AC adapter can be used f or po w er to
conserve batteries. The adapter is not a charger
and will not charge batteries. The adapter connects
to the bottom of the thermometer. When the adapter
is connected, the batteries are disconnected. Refer
to the ACCESSORIES section for adapter
information.

CONNECTING AN RTD
Note: Be sure your instrument setting matches the
RTD y ou are using (alpha of 0.00385 or 0.003916).
See SELECTING RTD SENSITIVITY (ALPHA)
on page 14. Insert the 3-pin plug into the mating
connector on the top of the instrument.
