3.0 PROBES
One of the key features of the Wahl Thermocouple Heat-Prober is a standard miniature
thermocouple connector used in the meter. Thermocouple connections are color
coded by type. Use probes with the same color male plug as the female. Each Heat-
Prober is designed for use with a specific thermocouple Type K or S. A thermocouple
of the same type with a standard male thermocouple connector will fit the meter. No
adapters are needed. The thermocouple is compensated where the cold junction is
made and cold junction compensation occurs automatically.
Each meter face indicates the thermocouple type, the temperature range of use, and
the calibration in °F or °C, as shown in Figure 3-1.
