Martel Electronics BetaProbe TI/TI+ - Manual (Page 4)

3. Operation
Insertion Depth and Usage
The BetaProbe TI/TI+ should be inserted to a minimum depth of 2.5"
to obtain specified accuracy of measurement. The final 2 inches of the
probe should always be exposed to prevent high temperatures from
damaging the instrument's electronics or housing. See illustration
below.
For best results, allow ample time for the probe to stabilize before
recording measurements. The stability display is helpful for this.

Push the power button momentarily to turn the unit on or off.
Normal Operation

Controlling the Primary Data Display

either °C or °F as calculated since power up or since the last reset of
the values. Press and hold the Min/Max key for 2 seconds until "CLR"
