Press this button to turn the thermometer ON and perform a measure-
ment. When the button is released, the meter will automatically HOLD
(freeze) the last reading on the display for approximately 15 to 20 seconds
before automatically shuting OFF.
2.2.2 Mode Button
Pressing this button makes the thermometer enter and advance though
several functions including some programmable functions. The MODE
button is used to select a specific function (e.g. MIN, MAX) or to adjust an
Alarm or the emissivity.
To enter the mode program, press
MODE once. SET is displayed in lower
right hand corner.
When pressed consecutively, it will scroll through the following settings:
ε

ε
(Set) → ALM Hi (Set) → ALM Lo (Set) → MAX → MIN → K →
ε
SET is displayed in the lower right hand corner of the display when a
selected function is programmable (
ε
, ALM Hi, ALM Lo).
ε
: Emissivity may be adjusted with the

and

buttons to match a particu-
lar target. We recommend leaving it at 0.95 for general use.
ALM Hi: The Hi alarm set point is adjusted using the

and

buttons. When
this set point is reached the beeper will sound and ALM HI will be displayed.
ALM Lo: The Lo alarm set point is adjusted using the

and

buttons.
When this set point is reached the beeper will sound and ALM Lo will be
displayed.
MAX: The Max value measured will be displayed during measurement. While
in the MAX mode and when measuring, the MODE button will toggle the mea-
surement between MAX – MIN – Present reading – MAX.
MIN: The Min value measured will be displayed during measurement. While
in the MIN mode and when measuring, the MODE button will toggle the mea-
surement between MIN – Present reading – MAX – MIN.
K: The lower display will indicate the reading from the K-type thermocouple.
NOTE: If the thermometer is OFF, pressing the “MEAS” button for more than
4 seconds will set the thermometer in the MIN/MAX record mode when pow-
ered up.
