if the probe develops a fault. If the error 

message remains, contact our service 

department for further assistance.

affected if operated within a high frequency 

radio field, such as near a mobile phone, or if 

subjected to an electrostatic shock.

INSTRUMENT OPERATION

 

- The instrument 

is switched on by unfolding the probe until  

the display shows 

the temperature. 

The unit is turned 

off by folding the 

probe back into 

the side of the 

instrument. The 

probe should not 

be rotated more 

than 180 degrees 

as damage will 

occur. It is recommended to store the probe, 

in the closed position, when not in use.

Apply the probe to the substance to be 

measured. For optimum accuracy immerse 

at least 70 mm of the probe in the substance. 

DO NOT

 immerse any of the case parts in 

liquid. The probe should be allowed adequate 

time to stabilise to the temperature of the 

item to be measured.
