WHAT’S IN THE PACKAGE
Both models come in a white box with this user’s
manual. The DT61 includes one “K” type bead
thermocouple probe with a measurement range of
-40° to 572°F (-40° to 300°C). The DT62 comes with
two “K” type probes with the same range.
A variety of other “K” type thermocouple probes
with different sensor types, form factors and
temperature ranges are available from General.
QUICK START GUIDE
1. Obtain and install a “9V” battery.
2. Plug included “K” type thermocouple probe(s) into
the top jack(s).
3. Press the POWER button.
PRODUCT OVERVIEW
Figure 1 shows all of the controls, indicators and
physical features of the DT61 and DT62, including
the differences between their keypads and jack
configurations. Figure 2 shows all possible
indications on the LCD. Familiarize yourself with the
positions and functions of all controls, indicators and
physical features before moving on to the Setup
Instructions and Operating Instructions.

POWER button. Powers thermometer on and off.
TC TYPE button (DT61 only). Selects thermocouple
type (“K”, “J”, “T” or “E”)
T1/T2/T1-T2 button (DT62 only). Selects one of four
display options:
a) T1 on primary readout and T2 on secondary
readout
b) T2 on primary readout and T1 on secondary
readout
c) T1-T2 on primary readout and T1 on secondary
readout
d) T1-T2 on primary readout and T2 on secondary
readout
°C/°F/K button. Selects temperature unit of primary
and secondary readouts
MAX/AVG/MIN button. Pressed briefly, selects
whether maximum, minimum or average value of
measurement session (since thermometer was
powered on) is displayed on primary readout.
Pressed and held, exits Max/Min/Avg display mode
and resumes real-time display mode.
HOLD (ENTER) button:
• On DT61, pressing HOLD button briefly “freezes”
T1 value on primary readout.
• On DT62, pressing HOLD briefly freezes T1, T2 or
T1-T2 value on primary readout and T1 or T2
value on secondary readout (values held are
determined by setting of T1/T2/T1-T2 button).
• On DT61 and DT62, ENTER button is only used
to set system time format.
SETUP button. Initiates 7-step setup procedure
(see p. 7)
왖 and 왔 buttons. On DT61 and DT62, used to
enable/disable ambient temperature compensation

and change values of temperature compensation,
Auto Power Off triggering time, relative time clock
and local power line frequency. On DT62, also used
to select thermocouple type (during Step 1 of Setup
procedure).
