Before Use
Please ensure this unit is suitable to application.
Check temperature range and thermocouple type to ensure suitability for application.
Power
The instrument requires two AA or equivalent cells. These are not supplied with the unit.
When the batteries require changing the following symbol will be displayed:
Please ensure the screws holding the battery compartment are firmly tightened when inserting or replacing batteries
to ensure the IP67 rating is maintained.

To disable automatic switch off, hold
switch-off function until the unit is switched off.
Hold Function
To enable the Hold Function, press the "Hold"
Speedread
This is a function that gives an indicative reading within 14 seconds for poor thermal conductivity items. The use of
this function will reduce the accuracy to ±2˚C. For correct Speedread measurements the probe must be in good
thermal contact with medium under test prior to activating the function. A steep temperature gradient or wide
temperature and item under test are required. Speedread is suitable for core frozen food measurements and
hot/cold liquids. Good thermal contact is unlikely when a general purpose or between pack probe is used on the
surface of food produce. (Not suitable for use with between pack probe).
Insert probe and press
appears and the symbol will be displayed. This reading will automatically be held. Press
normal mode. If it is not possible to obtain a faster reading due to the similarity of probe tip temperature and the
temperature of item to be measured, then the
mode.
A,B A-B I/P MODE
This function allows a singular or dual port reading. By pressing the button and referencing the display with A or B or
A-B you can choose your preferred preference of port or both.
MAX/MIN Recorder
Press key to start. The instrument will display alternating
the maximum temperature reading and
temperature & symbol will be displayed. Press again to return to the actual temperature display.
NOTE: To reset MAX/MIN recorder function, switch instrument off.
NOTE: Some functions maybe inhibited while information is stored in MAX/MIN mode. This is to prevent inadvertent
parameter mixing whilst in any of the above modes.
