电子数显卡尺的故障主要出在机械卡尺和数显两部分。这里以 MAX-15型电子数显卡尺为例,介绍一下我们的点滴检修经验,供参考。一、修理方法故障1:示值不准,严重的会出现活动量爪(副尺)运动而数字不变。原因:触头及编码器太脏或接触不好。排除方法;将卡尺背面紧固螺钉取下,用电烙铁将导线焊掉(电烙铁要可靠接地或烧热后拔下插头,这样可以避免损坏电器元件),并作一记号以便安装。小心取下包括触头在内 Electronic digital caliper failure mainly in the mechanical caliper and digital two parts. Here to MAX-15 digital electronic caliper, for example, introduce our bit overhaul experience, for reference. First, the repair method Fault 1: indication is not allowed, there will be a serious amount of activity claws (foot) movement and the same number. Cause: The contact and encoder are dirty or not in good contact. Remedy; remove the fastening screw on the back of the caliper, soldering the wire with a soldering iron (unplug the soldering iron to be grounded reliably or heat, so as to avoid damage to electrical components), and make a mark for installation. Carefully remove the contacts included
