“RTD/ESC” button
Briefly pressing the button (<1.5 s) switches to
resistance temperature detector mode or changes the
sensor type.
Pressing and holding the button (>1.5 s) resets the
settings to the factory defaults or restores automatic
temperature compensation.

.
“V/Ω” button
Briefly pressing the button (<1.5 s) switches to volt-
age/resistance output mode.
Pressing and holding the button (>1.5 s) shows the
resistance value in “RTD” mode and the voltage value
in “TC” mode for approx. 3 s.
4
Power button
Pressing and holding the button (>1.5 s) turns the
device on or off.
Briefly pressing the button (<1.5 s) switches the
display illumination on and off during operation.
5
.
“▲/25%” button
Briefly pressing the button (<1.5 s) increases the
current numeric value of the selected decimal place
by 1 point.
Pressing and holding the button (>1.5 s) increases
the numeric value by 25% of the entire current range
(voltage/resistance/temperature).
6
“◄/0%” button
Briefly pressing the button (<1.5 s) moves the
selected decimal place to the left.
Pressing and holding the button (>1.5 s) decreases
the numeric value to 0% of the entire current range
(voltage/resistance/temperature).
7
