Replacing The Battery
The instrument will indicate ‘BAT LOW’ when the battery
needs changing.
To change the battery, firstly remove the unit from the
outer case. The battery compartment is on the rear of the
instrument. Using a small screwdriver ease back the tab
of the battery compartment. The compartment will then
lift away.
Open Circuit Sensor Detection
An error in the probe is shown on the display by a series
of bars ‘- - - - -’ coupled with the word ’INPUT’ at the top
of the display. This indicates either that the probe has an
error or the temperature is out of range.
Using The MAX / MIN Features
The MAX/MIN features are used to record the highest or
lowest temperatures. The MAX/MIN features are activated
by pressing the MAX/MIN key. When the key is pressed
the MIN annunciator is activated and the minimum
temperature is displayed on the secondary display. This is
updated whenever the minimum value is exceeded. The
MAX feature functions in the same manner and is
activated by pressing the MAX/MIN key again.
The main display continues to show the real time
measurement. To cancel the feature simply press the key
again.
Using The Hold Feature
The hold feature is used to store the current value. When
you press the key the current value will transfer to the top
right of the display, while the main display continues to be
updated. To cancel press the hold key again.
