FAQs

汽车测电笔有什么用途?

汽车测电笔用于检测12V/24V汽车电路——在排查车辆线路故障时,可追踪电源、搭铁和信号。

它同时适用于12V和24V车辆吗?

适用的。我们的汽车测电笔同时支持12V和24V系统,覆盖轿车、摩托车、卡车和房车。

如何用汽车测电笔测试保险丝?

在电路通电状态下,将探针分别接触保险丝的两端。如果只有一端点亮,说明保险丝已熔断。完整的测试步骤请参阅随附的说明书。

这些测电笔适合汽车专业人士使用吗?

适合。它们是快速、可靠的线路故障诊断工具,被广大汽修技师和汽车电工广泛使用。

我主要卖给零售汽配店而不是专业维修厂,汽车电笔该备哪些型号?

我们是温州工厂。零售汽配货架我们通常推荐 HW304、HW305、HW306 家族覆盖三个价位,加上 HW80 作为紧凑型入门笔。如果渠道是专业维修厂,HW170 和带数显的 HW68A/HW68B 就是我们为这类客户定位的产品,WILK302 和 WILK303 则是独立的品牌系列。告诉我们你的目标市场和价位,我们会为你的首批订单建议具体的型号组合。

决定下哪个订单时,HW68A 和 HW68B 有什么区别?

HW68A 是配直导线的数显汽车电笔,HW68B 是同一数显设计但配弹簧导线。两者承担相同的汽车检测功能,差别在于你的客户更习惯用哪种线去够到线束或电缆。具体电压范围和显示功能请看每个产品页的规格表。两个版本可以混在一个订单里,先测试动销情况再加大批量。

一个整柜订单可以混装多款汽车电笔吗?每个型号需要达到最低起订量吗?

可以,整柜订单可以混装型号。我们接受汽车电笔全系列的混装出货,包括 HW170、HW304 至 HW310,以及 WILK302、WILK303,可以放在同一个货柜里。每个型号仍需达到各自的最低起订量,把数量清单发给我们,我们会确认每款 MOQ,并标明哪些有现货、哪些需要生产时间。

能在汽车电笔上印我们的品牌并装入我们自己的包装吗?

可以。我们是温州工厂,在汽车电笔系列提供 OEM 品牌定制,可在 HW304 至 HW310、HW170 以及 WILK302、WILK303 等型号上印制你的 logo。你可以选择标准 CHINYOO 彩盒、普通散装,或带品牌设计的定制盒。把 logo 和盒型设计发给我们,下单前我们会确认印刷和模具费用。

How do I test a fuse without pulling it out?

With the circuit powered, touch one probe to each of the two small test points on the top of the fuse. A good blade fuse shows the same voltage on both points; a blown fuse shows supply voltage on one side and nothing on the other. If the fuse has no test points, pull it and check continuity instead.

What resistance should a good fuse read?

Close to zero ohms, typically under 1 Ω, with the continuity buzzer sounding. A blown fuse reads open circuit, which most meters show as OL. Remember that the test leads add a fraction of an ohm of their own, so touch the probes together first and subtract that figure from what you see.

Can I test a circuit breaker with a multimeter?

Yes, with the circuit isolated. Switch the breaker off, prove the load side is dead with a contact tester, then measure continuity across the breaker terminals: a healthy closed breaker reads near zero and a tripped or failed one reads open. Never test a breaker with the circuit live, and treat a breaker that trips repeatedly as a circuit fault to be found rather than a breaker to be replaced.

Why does a fuse show continuity but the circuit still does not work?

Continuity proves only that the fuse element is intact. The usual causes are a corroded fuse holder, a fuse seated in the wrong slot, a relay or switch further down the circuit, or a second fuse on the same feed. Measure voltage at the fuse with the circuit on: if voltage arrives on one side and not the other, the fault is the contact rather than the element.

批发的最低起订量是多少?

我们既支持小批量试单,也承接整柜批发。请告知您需要的型号和数量,我们的销售团队将在24小时内回复报价和交期。

是否支持使用我们自有品牌的OEM/ODM定制?

支持的。我们是一家 2008 年创立的工厂,提供OEM/ODM服务,包括定制标签、包装和可调节测量量程。把您的规格要求发给我们,其余交给我们处理。

批量下单前能拿样品评估吗?

可以,我们鼓励在批量下单前先订样品,让你亲自确认做工和校准。样品走快递,一般 3 到 7 个工作日到货,样品费用会在同一型号的首个批量订单中抵扣返还。通过联系表单或邮件告诉我们需要的型号,我们报样品价,付款后即发货。
