To the start, put on the 4~5 liquids drops on the liquids dropping mouth, press ‘Read’ one time, the meter will automatically measure one time, and display the measured value. This measured result has already automatically temperature compensated. Measured result is shown on Diagram.

As the overrange, it will display ‘HHH’ or ’LLL’,

If the liquids drop mouth has no liquids,it display ‘----’

As press ‘Read’ Key 2secondsmeter will make the automatic measurements of fixed times ,until the measurement finish, the multi-fu function return to the Scale display status.                                       P4.2.5  

Note : Multi-functiondisplay remaining times of automatic measurement, each one time automatic measurement passed, the number will be deduct by 1. Default automatic measurement times are 15 times.
