Minimum and maximum reading option
The Digitemp may be fitted with an option which stores the maximum and minimum measured temperatures. These temperatures
may be displayed or cleared by means of magnetically-operated switches without opening the sealed case.
To display the minimum and maximum temperatures : Place a bar magnet on the top right-hand side of the case within the
box marked Min - Max on the instrument label. The DigiTemp display will then alternate between the maximum and minimum val-
ues as long as the magnet is held in place. The maximum temperature is shown after the display message Hi and the minimum
value follows Lo.
To reset (clear) the minimum and maximum values : Place a bar magnet on the top left-hand side of the case within the box
marked Min-Max Clear on the instrument label. After approximately 5 seconds the minimum and maximum values will be
cleared, confirmed by the display message HiLo CLrd. Note that the minimum and maximum readings will also be cleared if the
battery is removed.
