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.
