Warnings and Precautions
•
When measuring surface temperatures, the potential
between the measured surface and earth ground must not
exceed 24V AC or DC. Voltages above 20V are dangerous.
•
Inspect the instrument and probe before every use. Do not
use damaged parts.
•
Never ground yourself when taking measurements in
electrical circuits. Do not touch exposed circuit elements or
probe tip.
•
To avoid damage or burns, do not make temperature
measurements in microwave ovens.
•
Do not operate instrument in an explosive atmosphere.
Caution: Repeated sharp flexing can break the thermocouple
leads. To prolong lead life, avoid sharp bends in the leads,
especially near the connector.
Preparation for Use - Unpacking
Your shipping carton should include the digital thermometer
with four 1.5V AAA size batteries installed, one 1.2m type K
thermocouple probe, a soft carrying case and this manual. If
any of the items are damaged or missing, return to the place of
purchase for an exchange.
Measuring Procedure
1. Connect the K-type thermocouple probe to the instrument.
2. Turn instrument on by sliding the function switch to the
desired resolution (1° or 0.1°).
3. Push the selector key to select °C or °F (corresponding
symbol appears on display).
4. Apply the probe to the medium that the temperature is to
be measured.
5. Read the measured temperature on the digital display.
DATA HOLD: When measuring in tight locations or dark areas
you can push the DATA HOLD button to “freeze” the reading
on the display.

is displayed. Push the DATA HOLD button
again to resume normal display of current value.
MAX HOLD: Push this button to monitor a temperature over a
longer time period. MAX is displayed. The maximum value is kept
on the display and is updated each time a higher value is measured.
Pressing DATA HOLD while MAX recording is activated interrupts
recording; pressing DATA HOLD again resumes recording. Press
MAX HOLD again to return to normal measuring mode.
