Temperature
Plug any Type K thermocouple directly into the meter to measure
temperature. Measure outdoor dry bulb temperature for target superheat
while at the condensor with the Type K thermocouple input.
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, °F will show on top display and °C on bottom display.
Range:
-58°F to 2372°F, (-50°C to 1300°C)
Resolution:
0.1°
Accuracy:
±(1°F)* 32°F to 120°F, ±(1°C) 0°C to 49°C
±(1%+2°F) 32°F to 932°F, ±(1%+1°C) 0°C to 500°C
±(2%+6°F) -58°F to 32°F, ±(2%+3°C) -50°C to 0°C
±(2%+6°F) 932°F to 2372°F, ±(2%+3°C) 500°C to 1300°C
Sensor type:
Type K thermocouple
Overload protection:
30 VDC or 30VAC rms

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 position.
2. Plug one thermocouple to be
calibrated into the Type K input.
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 thermocouple probe
and let it stabilize. Keep stirring
water to prevent thermocouple from
direct contact with ice.
6. Use a small screwdriver to adjust
calibration Temp Cal pot below the
battery as close to 32°F(0°C) as you
would like.
Note: J1-J2 switch is for factory
calibration purposes only. Do not
switch from J2.
