Digital type vacuum meter is diagnosing the application in detecting
From;  Author:Stand originally
In last few years, diagnose ceaseless maturity of the technology as home, more and more maintenance technician begin vacuum meter of have the aid of detect the function undertakes maintaining. Because the error is damaged greatly, easily and vacuum meter of traditional type of pressing with a finger detects wait for an element certainly hard as a result, begin to be replaced by digital type vacuum meter stage by stage. In this union digital type vacuum meter is diagnosing the application in detecting to undertake an analysis.

Vacuum meter

One, the advantage of digital type vacuum meter

1. is measured the result is accurate

Digital type vacuum meter shows with the number measure an outcome, be clear at a glance, without factitious reading error.

2. measures range greatly

The measurement that digital type vacuum meter compares vacuum meter of type of pressing with a finger commonly limits wants big, the 2 ~ that are avometer of type of pressing with a finger normally 3 times.

3. overload ability strong

Digital type vacuum meter has more perfect protection circuit commonly, won't damage commonly the integrated circuit inside the watch.

4. function is patulous convenient

Interior of digital type vacuum meter has large-scale integrated circuit, and it is to use a number to demonstrate a skill, because this is a few more patulous in original test function new function, mix especially the online function of the computer, can make digital type vacuum meter is strengthened greatly in intelligent respect.

2, the test method of digital type vacuum meter

The preparation before 1. test

Diagnose breakdown to use digital type vacuum meter better, must ensure before the test ignition when with idle fast limiting value is in normal limits, here premise falls, assume the cost that one-sided spends from normal vacuum, show engine existence trouble.

2. differs according to engine trouble of engine of rotate speed judgement

When measuring, the vacuum of vacuum meter is sure to originate directly the manifold that take energy of life, because have only,be being spent into the vacuum of gas manifold is to originate directly the vacuum of engine. The vacuum that leaves for divisional and different operating mode spends the breakdown that the report that be worth place comes out, test engine spends into the vacuum of gas manifold can divide for 3 kinds of main types: Idle quickens test and test of exhaust system block fast test, urgently.
