Problems solved by technology

In this way, it is impossible to confirm whether the linear value of the potentiometer is normal when the voltage is applied
And when the potentiometer is installed and there is an abnormal phenomenon in the live inspection, it is impossible to determine whether it is a problem with the potentiometer itself or a problem during installation and welding.

Embodiment Construction

[0009] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0010] see figure 1 , the present invention includes an installation base plate 1 and an angle plate 15 with a dial 16 arranged on the installation base plate 1. An indexing head 24 and a nut stand 8 are respectively arranged on both sides of the angle plate 15. On the installation base plate 1 A T-shaped slot is provided, and the angled plate 15 and the key 11 are fixed by screws 10. The key is put into the T-shaped groove of the mounting plate, and after adjusting the position, the angled plate and the installation base plate are fixed with screws 12. The said angled plate 15 and the A mandrel 25 is arranged between the dividing heads, and the through hole 18 concentric with the mandrel 25 is provided on the said gusset 15, and this mandrel 25 one ends are clamped on the chuck of the dividing head 24, and the mandrel 25 The other end is provided with an in...

Abstract

The invention discloses a linear tester and test method for potentiometers. A potentiometer is fixed on an angle plate, and the angle plate is embedded with a meter dial. A mandrel is provided with an adjustable pointer, and after the potentiometer is connected with a power supply and an electric meter, an index head handle is stably and slowly rotated by hand, thereby realizing the stable and slow rotation of the potentiometer and measuring the change process of linear voltage values of the potentiometer. The tester and test method disclosed by the invention have the advantages that the situation that unqualified potentiometers are put into production is avoided, the unnecessary economic losses and the repeated operations of workers are reduced, and the linear test on purchased potentiometers can be performed firstly by inspection personnel.

Description

technical field [0001] The invention belongs to detection instruments, and in particular relates to a potentiometer linearity tester and a test method. Background technique [0002] At present, for the potentiometers purchased from outside, the inspectors do not have a tester, so they can only turn the spindle of the potentiometer by hand to test the change of its resistance value. In this way, it is impossible to confirm whether the linear value of the potentiometer is normal when the voltage is applied. And when the potentiometer is installed with an abnormal phenomenon in the live inspection, it is impossible to determine whether it is a problem with the potentiometer itself or a problem during installation and welding. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art, and provide a potentiometer that can prevent unqualified potentiometers from flowing into the production process, r...
