mV ntsuas
1. Qhov "Settings" hloov mus rau "Kev Ntsuas", thiab "pH / mV" xaiv hloov mus rau "mV";
2. Ntxig cov electrode rau hauv cov tshuaj yuav tsum tau kuaj, thiab tom qab nplawm cov tshuaj sib npaug, cov electrode peev xwm (mV) tuaj yeem nyeem tau.
3. Yog hais tias lub teeb liab ntsuas ntau tshaj qhov ntsuas qhov ntsuas, lub vijtsam zaub yuav tsis teeb thiab lub tswb ceeb toom yuav raug tshaj tawm.
pH calibration thiab ntsuas
Calibration: Lub ntsuas yuav tsum tau ntsuas ua ntej ntsuas pH. Feem ntau hais lus, thaum lub cuab yeej siv tas li, nws yuav tsum tau ntsuas ib zaug ib hnub. Cov kauj ruam yog raws li nram no:
a) Qhov "Settings" hloov mus rau "Kev Ntsuas", thiab "pH / mV" xaiv hloov mus rau "pH";
b) Kho qhov "kub" pob qhov rooj kom cov kab dawb ntawm cov pob qhov rooj taw qhia rau qhov sib piv cov nqi ntsuas kub;
c) Tig lub pob qhov "Slope" clockwise mus rau qhov kawg (100 feem pua);
d) Ntxig lub electrode ntxuav rau hauv cov tshuaj tsis muaj pH ntawm 6.86;
e) Kho qhov "qhov chaw" pob qhov rooj kom lub ntsuas ntsuas kev nyeem ntawv zoo ib yam nrog tus nqi pH ntawm cov tshuaj tsis haum ntawm qhov ntsuas kub tam sim no;
f) Ntxuav cov electrode nrog dej distilled, ces muab tso rau hauv cov txheej txheem buffer tov nrog pH nqi ntawm 4. pH tus nqi ntawm cov tshuaj tsis nyob ntawm qhov ntsuas kub tam sim no;
g) Rov ua dua (e) mus rau (f) kom txog rau thaum lub "qhov chaw" lossis "kev nqes hav" hloov kho cov pob qhov rooj. Nyob rau ntawm no, lub ntsuas yog calibrated. "Position" thiab "Slope" yuav tsum tsis txhob txav mus txog rau thaum lub calibration tom ntej.
Kev ntsuas pH: Lub ntsuas pH tuaj yeem siv los ntsuas pH. Cov kauj ruam yog raws li nram no:
a) Qhov "Settings" hloov mus rau "Kev Ntsuas", thiab "pH / mV" hloov mus rau "pH";
b) Ntxuav lub taub hau electrode nrog dej distilled, thiab tom qab ntawd ntxuav nws ib zaug nrog cov tshuaj ntsuas;
c) Siv lub ntsuas kub ntsuas kub los ntsuas qhov ntsuas kub ntawm cov tshuaj yuav tsum tau kuaj;
d) Kho qhov "kub" pob qhov rooj kom cov kab dawb ntawm lub pob qhov taw qhia rau qhov sib piv cov nqi ntsuas kub;
e) Ntxig cov electrode rau hauv cov tshuaj yuav tsum tau kuaj, thiab tom qab nplawm cov tshuaj kom cov tshuaj sib xws, nyeem pH tus nqi ntawm cov tshuaj.
