Kev piav qhia

Peb Phase Zog Meter yog ib qho kev ntsuas uas feem ntau siv hauv cov chaw ua lag luam, cov chaw lag luam ntse, cov tsev rau pej xeem, cov chaw siv hluav taws xob, thiab lwm yam. Nws tuaj yeem tiv thaiv kev siv hluav taws xob zoo thiab nyab xeeb ntawm cov neeg siv, thiab kuj muaj ntau yam tshwj xeeb hauv kev ua haujlwm. Nws muaj lub zog ntsuas kev ua haujlwm, uas tuaj yeem siv rau pem hauv ntej thiab thim rov qab lub zog ua haujlwm, lub zog rov ua haujlwm, thiab lub zog khov, uas tuaj yeem pab cov neeg siv nkag siab txog kev siv hluav taws xob hauv lub sijhawm tiag tiag thiab faib hluav taws xob tsim nyog. Nws tuaj yeem sau cov programming thiab zeroing kev ua haujlwm ntawm lub ntsuas hluav taws xob thiab kev khiav haujlwm ntawm lub ntsuas hluav taws xob hauv lub sijhawm tiag tiag kom ntseeg tau tias kev ua haujlwm zoo ntawm lub ntsuas hluav taws xob. Kev ua haujlwm dav dav tuaj yeem pab cov neeg siv nyeem cov ntaub ntawv ntsuas tau zoo dua.

Nta

1. Lub txee ntawm Peb Phase Zog Meter muaj kev sib khi zoo thiab tiv thaiv kev cuam tshuam, yog li nws tuaj yeem ua kom muaj kev ntsuas raug.

2. Peb cov khoom yog ua los ntawm ABS cov khoom siv hluav taws xob, uas muaj kev ruaj ntseg zoo dua.

3. Lub phab ntsa-mounted tsim ua rau installation yooj yim dua thiab txuag lub sij hawm.

4. Lub vijtsam LCD tso cai rau koj pom cov ntaub ntawv kom meej meej thiab tiv thaiv kev ua yuam kev.
