TEMPERATURE DIFFERENCE ( HI 9056 only)
The difference between the temperature
measured by the two probes can be dis-
played by simply pressing ∆T. A "∆" will
appear on the left-hand of the display to
indicate this function.
LOW BATTERY DETECTION
To save battery life, HI 9056 and HI 9057
will switch off after 5 minutes.
When the battery is low the
