Indawo yoVavanyo ngumqulutage ixabiso elenzelwe iinjongo zokuqinisekisa. Eli xabiso lahlulwe layimihlathi emibini: Indawo kunye neXabiso. Indawo ibhekisa apho ixabiso lovavanyo lingena ngaphakathi koluhlu lovavanyo. I-Pos FS imele i-positive full-scale kunye ne-Neg FS imele isikali esipheleleyo esingalunganga. Ixabiso libhekisa kumthamotagIxabiso le-e liza kuqinisekiswa kwaye likwi-volts.
Iiyure ezingama-24
Ikholamu ye-24-Hour Ranges iqulethe iMida ePhakamileyo kunye neMida ePhantsi yexabiso lenqaku lovavanyo. Oko kukuthi, xa ifowuni ingaphakathi kwesithuba sokulinganisa iiyure ezingama-24, ixabiso lenqaku lovavanyo kufuneka liwe phakathi kwamaxabiso aphezulu nasezantsi. Imida ephezulu nangaphantsi ibonakaliswe kwiivolthi.
1-Unyaka Ranges
Ikholamu ye-1-Year Ranges iqulethe iMida ePhezulu kunye neMida esezantsi yexabiso lenqaku lovavanyo. Oko kukuthi, xa isixhobo singaphakathi kwesithuba sokulinganisa sonyaka we-1, ixabiso lenqaku lovavanyo kufuneka liwe phakathi kwamaxabiso aphezulu nasezantsi. Imida ephezulu nangaphantsi ibonakaliswe kwiivolthi.
Izixhobo zokubala
Akwenzeki ukunyenyisa isisombululo sekhawuntara/izibali-xesha. Ngoko ke, la maxabiso awanawo unyaka omnye okanye iiyure ezingama-1. Nangona kunjalo, indawo yovavanyo kunye nemida ephezulu kunye nesezantsi inikezelwe ngeenjongo zokuqinisekisa.
