Compatibility & Fitment

• Designed for digital multimeters (DMMs) with a temperature measurement function
• Compatible with instruments that accept K-Type thermocouples via standard banana jack inputs
• Direct fit for many Fluke multimeters and other brands with compatible inputs

When to Replace

• Temperature readings are inaccurate, erratic, or unstable
• The multimeter displays an open-loop or "OL" error with the probe connected
• Visible damage to the wire insulation, bead sensor, or banana plugs
• Intermittent readings when the cable is moved

Installation Tips

• Set the multimeter to the Type-K temperature setting before connecting the probe.
• Insert the shrouded banana plugs fully into the correct input jacks on the multimeter, observing polarity markings.
• Allow the thermocouple bead sufficient time to reach the temperature of the medium being measured for an accurate reading.
• Do not exceed the probe's maximum rated temperature of 500°F (260°C).
