INTRODUCTION
This instrument is a portable 4½ digit, compact-sized
digital thermometer designed to use external K-type
thermocouples as temperature sensor. Temperature
indication follows National Bureau of Standards and
IEC 584 tem-perature/voltage tables for K-type
thermocouples. One K-type thermocouple is supplied
with the thermometer.
SAFETY INFORMATION
It is recommended that you read the safety and
operation instructions
before using this t
hermometer.
WARNING
To avoid electrical shock, do not use this
instrument when working voltages at the
measurement surface over 24V AC or 60V DC.
WARNING
To avoid damage or burns, do not make temperature
measurement in microwave ovens.
CAUTION
Repeated sharp flexing can break the thermocouple
leads. To prolong lead life, avoid sharp bends in the
leads, especially near the connector.
The
symbol on the instrument indicates that the
operator must refer to an explanation in this manual.

OPERATING INSTRUCTIONS
1.
“°C/°F” Button: Selecting the Temperature Scale
Readings are displayed in either degrees Celsius(°C)
or
degrees Fahrenheit(°F). When the thermometer is
turned on, it is set to the temperature scale that was in
use when the thermometer was last turned off. To
change the temperature scale, hold down for 2 seconds
“APO >2S°C/°F” key.
2.
“HOLD” Button
Press the “HOLD” key to enter the Data Hold mode,
the
“HOLD” annunciator is displayed. When HOLD
mode is selected, the thermometer held the present
readings and stops all further measurements. Press the
“HOLD” key again cancels HOLD mode, causing the
thermometer to resume taking measurements.
3.
“REL” Button
Press “REL” key to enter Relative mode, zero the
display, and store the displayed reading as a reference
value and annunciator REL is displayed. Pressing
“REL” key over 2 seconds to exit the relative mode.
4.
“APO” Button
Pressing “APO >2S °C/°F” key to trigger on or off
APO mode, and then APO annunciator will appear or
disappear on the display. Power is automatically turn off,
if no operation for a period of time, and “APO”
annunciator is displayed at upper-left corner when APO
function is enabled.
5.
“MIN/MAX” Button
Press “MIN/MAX” once to begin recording MIN and
MAX. Press “MIN/MAX” to select MIN or MAX or
MAX-MIN or AVG. Hold down for 2 seconds to exit
MIN/MAX function.
In the MIN/MAX record mode can not power off,
must leave MIN/MAX record mode then power off.
