Button (Double Duty)
Press
button to select the Manual Range mode and turn off
the "AUTO" annunciator.
In the Manual Range mode. Each time you press
button,
the range (and the input range annunciator) increments, and a new
value is displayed. To exit the Manual Range mode and return to
autoranging, press and hold down
button for 2 seconds. The
"AUTO" annunciator turns back on.
In infrared temperature measurement "IR" mode, pressing this
button increases the Emissivity value of the target.
Button
In thermocouple temperature "T/C" mode, pressing this button
scrolls thru T1, T2, and (T1-T2) temperature readings.
Button
Press
to enter the MAX MIN AVG Recording mode (manual
range only). The "REC", "APO" annunciator turns on and tenable
the APO mode. Meter do not take records when the display reads
overrange (+/- OL).
Push
to cycle through the maximum(MAX), minimum(MIN),
average(AVG) and present readings. Press and hold down the
for 2 seconds to exit and erase recorded reading.
Button
Pressing the
key to enter the Data Hold mode, the "HOLD"
annunciator is displayed. When HOLD mode is selected, the meter
held the present readings and stops all further measurements.
Pressing the
key again to cancel HOLD mode causing
meter to resume taking measurements.
Button
Press
to enter the Relative mode, zero the display, and
store the displayed reading as a reference value. The relative
mode annunciator "REL" is displayed.
Press
again to exit the relative mode.
Button
Pressing this button toggles the temperature display between
Degrees Celsius(°C) or Degrees Fahrenheit(°F).
Button
Press
button to toggle on and off of display backlight. The
backlight will switch-off automatically after 30 seconds.
Button
Press & hold to turn on the laser beam. Release the button to
turn off the laser beam. When the laser beam is on, a laser icon
appears on the display.
There is a switch in front of the laser aperture select between
laser Dot or laser Circle.
