the current temperature reading. By pressing the ‘D’

the key is released, the parameter value is shown

value, then press k to select the next digit.
4. When the right most digit is blinking and correct,
press the ‘E’ key to store the value and return to nor-
mal meter operation.
5. If a mistake is made at any point before the ‘E’ key is
pressed, press the ‘X’ key to cancel the operation and
return to the default display.
