Third, action
1Sampling: press the microcomputer 'Confirm /Cancel ' Key display appears '00: 00 00' , And then press 'Cent ' Select the desired time maximum time this key is 59Minutes, if 59Not enough, and then press 'Hour ' Keys, this key the maximum time for 99Hours, when time is selected, and then press 'Confirm /Cancel ' Key-that is, up-sampling. Sampling pump working computer countdown status when the computer displays '0: 00' Host when the subject is computer controlled automatic power off.
To reset or shutdown in advance, just press 'Confirm /Cancel ' Key, you enter the reset or shutdown. The display shows '0: 00' .
2Charging: plug the AC power cord insert instrument 220VAC input from the mains, the instrument is in a shutdown state, and once fully charged in about 6~ 8Hours (standard charging time). Each charge can be continuous or cumulative work 12Hours or so.
Note: placed in ventilated and dry place for a long time. If 2More than a month without recharging should be carried out to ensure high service life of the lithium-ion battery for mine.
Equipment handling, carrying process should prevent other touch microcomputer 3Keys to avoid the boot.
