Setup and Operation
1. Press the Power on/off button to turn unit on.
Using Thermocouple Input(s)
1. Plug the type K thermocouples into the T1 and T2 input
connectors.
2. After one second the thermometer displays the first
readings (T1 on upper display, T2 on secondary dis-
play). If no thermocouple is plugged into the selected
input or the thermocouple is not properly connected,
the display will show "- - - -". If the temperature being
measured is outside the unit’s valid range, the display
will show “OL” (overload).
Using Infrared Input
1. Purchase optional infrared wand (model 20250-24).
2. Plug the IR wand into the T3 (IR) input connector.
“T3 - - - -” will show on screen. If the IR wand is not
connected, “T3 - - - -” is not shown on the screen.
3. Press the SCAN button on the IR wand to begin
measuring. The IR (T3) measurement is shown on
the tertiary display.
Displaying Temperatures
1. Press °C/°F/K button to select desired temperature unit:
Celsius (°C), Fahrenheit (°F), or Kelvin (K).
2. As a default, the T1 temperature reading appears in
the primary display, the T2 reading in the secondary
display, the T3 reading in the tertiary display.
3. Use the DIF/T1–T2–T3 button to toggle between
showing the T1 (type K), T2 (type K), T3 (infrared),
T1–T2, T1–T3, T2–T3 (temperature differentials)
measurement in the primary, secondary, or
tertiary display.
