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.
Insulated 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
Thermocouples (T/C) are not calibrated directly. Instead, each T/C jack
(T1 and T2) must be calibrated to the particular T/C that is plugged into it.
Though it’s possible for a calibration to hold for years, it’s best practice to
calibrate regularly if only to verify accuracy. Labelling your T/C, T1 or T2,
will help ensure using the same T/C for T1 and T2 ports.
Calibration is quick and easy, requiring just a known temperature to
calibrate to. Ice water is probably the most accurate and readily available
known temperature (32.0°F, 0.0°C) in the field
.
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.
