Yuav ua li cas t GVDA GD128PLUS 9999 suav Rechargeable Smart Multimeter nrog Bracket
1. Kev ntsuas tus kheej
Nias thiab tuav lub HOLD khawm kom lub hwj chim rau, tos kom tiav cov zaub kom tiav, tso tawm, thiab tom qab ntawd luv-nias khawm tuav peb zaug kom nkag mus rau hom calibration. Lub sijhawm no, LCD qhia CAL (thawj calibration yuav flash), thiab tom qab ntawd qhia txog qhov ua tiav %. Thaum lub calibration tiav, PAS thiab Beep yuav tshwm sim. Lub beep qhia tias tus kheej-calibration tiav thiab 100mV calibration tau nkag.
Nco tseg: Thaum ua qhov ntsuas tus kheej, qhov kev xeem coj yuav tsum tau tso tseg thiab tsis tuaj yeem txuas rau ib qho teeb liab.
2.100mV DC voltage calibration(yuav tsum tau calibrated, tuaj yeem xaiv los ntawm nias tus yuam sij SEL)
Hauv hom kev ntsuas tus kheej, nias tus yuam sij SEL tawm ntawm tus kheej-calibration thiab nkag mus rau 100mV calibration. Lub LCD qhia tus nqi mV (thawj calibration yuav flash). Lub sijhawm no, ib qho kev tawm tswv yim sab nraud yog 100mV. Nias lub khawm tuav ib zaug. Lub LCD yuav tso saib PAS thiab lub suab Beep yuav tshwm sim li ntawm 2 vib nas this, qhia txog 100mV. Calibration tiav thiab ntsuas qhov ntsuas hluav taws xob tau tshwm sim.
3.100K kuj calibration(xaiv calibration raws li xav tau, nias SEL key xaiv):
Nias tus yuam sij SEL dua, thiab LCD yuav tso saib tus nqi tsis kam (thawj calibration yuav flash). Lub sijhawm no, cov tswv yim sab nraud yog 100K. Nias lub khawm tuav ib zaug. Lub LCD yuav tso saib PAS thiab Beep li ntawm 1 thib ob, qhia tias 100K calibration tiav, thiab qhov ntsuas qhov ntsuas yuav raug tso tawm.
4. Ambient kub calibration(yuav tsum tau ntsuas, tuaj yeem xaiv los ntawm nias SEL):
Nias tus yuam sij SEL dua, lub LCD yuav tso saib 25.0 degree (thawj calibration yuav flash), kho raws li qhov ntsuas kub hauv tsev tam sim no los ntawm tus yuam sij SEL, luv nias kom txo los ntawm 0.5 degree , ntev nias thiab tsis tu ncua nias kom nce los ntawm 0.5 degree , tom qab qhov kev hloov kho tiav, nias lub khawm tuav ib zaug, 1 Nyob rau hauv li vib nas this, lub LCD qhia PAS thiab beeps, qhia tias qhov ntsuas kub ntawm ambient calibration yog ua tiav, thiab qhov ntsuas kub ntsuas qhov ntsuas kub tau tshwm sim.
Lus Cim: Thaum lub sij hawm calibration, cov kev xeem coj yuav tsum tau sab laug floating thiab tsis tuaj yeem txuas nrog ib qho teeb liab.
5.100mA tam sim no calibration(yuav tsum tau calibrated):
Hauv hom kev ntsuas tus kheej, ntxig qhov kev xeem coj mus rau hauv mA tam sim no jack, thiab LCD yuav tso saib tus nqi tam sim no (nws yuav flash rau thawj calibration). Lub sijhawm no, tawm tswv yim DC 100mA sab nraud. Nias lub khawm tuav ib zaug. Lub LCD yuav tso saib PAS thiab lub suab Beep yuav tshwm sim li ntawm 1 thib ob, qhia tias tam sim no calibration tiav lawm. , thiab qhia txog qhov ntsuas tam sim no.
6.1A tam sim no calibration (yuav tsum tau calibrated):
Hauv hom kev ntsuas tus kheej, ntxig qhov kev xeem coj mus rau hauv A tam sim no jack, thiab LCD yuav tso saib tus nqi tam sim no (thawj calibration yuav flash). Lub sijhawm no, tawm tswv yim DC 1A sab nraud, nias lub khawm HOLD ib zaug, thiab LCD yuav tso saib PAS thiab lub suab nrov nrov li 1 thib ob, qhia tias qhov ntsuas tam sim no tiav. , thiab qhia txog qhov ntsuas tam sim no.
7. Tom qab calibration tiav lawm,nias thiab tuav lub hwj huam khawm kom tua lub cuab yeej.
Calibration yuam kev code:
Er1: Calibration cov ntaub ntawv sau yuam kev, feem ntau yog teeb meem kho vajtse sab nraud;
Er2: Calibration cov ntaub ntawv sau tsis raug, tus nqi capacitance ntawm VPP tus pin tsis raug lossis muaj teeb meem kev khi lossis vuam;
Er3: Tus naj npawb ntawm calibrations tau tas lawm, txhua qhov calibration point yuav calibrated mus txog 16 zaug;
ErC: Teeb liab yuam kev, feem ntau tshawb xyuas lub teeb liab lub zog thiab polarity.
