Dual Temperature (T1, T2, T1-T2)
Plug anyType K thermocouple directly into the meter to measure
temperature. Test for proper airow across the evaporator coil by
measuring delta T with the dual temperature inputs.
Cold junction is located inside the meter and allows for accurate
measurements even in rapidly changing ambient temperatures (going
from rooftop to freezer). No adapter is required.
By default,T1 will show on top display andT2 on bottom display. Press
SELECT button once to displayT1 on top and T1-T2 on the bottom. Press
SELECT button again to displayT2 on top and T1-T2 on the bottom.

Change Units (°F or °C)
By default, temperature units are set to Fahrenheit (°F). In
Temperature dial position, press SELECT button for 1 second to toggle
between Fahrenheit (°F) and Celsius (°C).

Temperature Calibration
For accuracies of ±1°F, calibrate both
thermocouples to a known temperature. A glass
of stabilized ice water is very close to 32°F (0°C)
and is usually very convenient but any known
temperature can be used. Ideally you should
calibrate to a known temperature closest to the
temperatures you will be testing.
1. Rotate dial to the °F °C, T1-T2
position.
2. Plug one thermocouple to be
calibrated into the T1 Type K jack.
3. Unscrew A and B and remove the
battery cover.
4. Stabilize a large cup of ice water.
Stir the ice with the water until
temperature stays at a stable value.
5. Immerse the T1 thermocouple
probe and let it stabilize.
Keep stirring water to prevent
thermocouple from direct contact
with ice.
6. Use a small screwdriver to adjust
calibrationT1 Temp Cal pot below
the battery as close to 32°F(0°C) as
you would like.
7. Repeat step 2-6 and replace T2 for
T1 for T2 thermocouple.
Note: J1-J2 switch is for factory
calibration purposes only. Do not
switch from J2.
