Adapter plug connects to the DMM "V" volts input terminal and the Adapter's
negative plug connects to the DMM "COM" (-) input terminal. Power the DMM and set
its function switch to the mV DC range. (Use the VDC setting if mV setting is not
available). If you are using an Auto Range DMM, disable the Auto Range function
and use Manual Range mode.

Power the Adapter and Select Temperature Units
Move the "OFF/C/F" Switch to either the degrees F or C position as desired. The
Adapter is now powered (observe the red LED power light) and the units of
measure are selected. To remove power to the meter, move this switch to the OFF
position and observe that the red LED indicator extinguishes. If the red status LED
does not light when the meter is switched on, replace battery.

o
F). Contact Extech or you local distributor for other thermocouple probe
types.
