IR/K:
The selector switch is located
inside the battery compartment in the
handle. Simply swing open the two
piece handle and position the slide
switch. Set to IR for non-contact
measurements or set to K for contact
measurements. When set to K, a K-type
probe must be connected to the K-type
connector located at the bottom right
side of the handle. If a probe is not
connected the thermometer will display
“open” when the trigger is pulled.
TRIGGER:
Press and hold the trigger
button on the 381a. The thermometer
will power up and the laser will be
visible (unless in contact “K” mode).
After releasing the trigger, the
thermometer will hold the last
reading then automati-cally turn
off after 10 seconds. For extended
measurement time simply hold the
trigger on and the termometer will
stay in scan mode.
°F/°C:
The selector switch
is located inside the battery
compartment in the handle.
Simply swing open the two
piece handle and position
the slide switch.
