Simple test pen

Abstract

The invention discloses a simple test pen which comprises a pen-shaped body and a test probe arranged at the front end of the pen-shaped body. The pen-shaped body is provided with a gear changing device capable of displaying the measurement range of the pen-shaped body. The simple test pen is reasonable in structural design, the pen-shaped body is provided with the gear changing device, the measurement range of the pen-shaped body can be conveniently and quickly obtained by a tester, a measurement gear on a measurement device does not need to be checked before measurement for confirmation of the measurement range of the pen-shaped body, it is avoided that the tester is distracted when checking the measurement device, safety of the tester and equipment safety are guaranteed, and measurement precision is improved; the gear changing device is provided with a plurality of measurement gear identifications, the gear changing device can be adjusted to display the corresponding measurement gear identifications according to the measurement range of the measurement device during measurement, the application range is wide, the simple test pen is convenient to use, and work efficiency is improved; additionally, the simple test pen is simple in overall structure and low in cost and facilitates wide popularization.

Description

technical field [0001] The invention relates to a simple test pen, in particular to a simple test pen capable of displaying its measuring range. Background technique [0002] Traditional multimeters, insulation testers or other simple test pens only have the function of connection and conduction. When measuring, because the objects to be measured are different, it is necessary to adjust the measurement device accordingly range of measurement gears to improve measurement accuracy or avoid damage to measurement equipment. Therefore, before the measurement, people need to frequently check the measurement gear on the measurement equipment to confirm the measurement range. It is troublesome to use, affects work efficiency, and is easily distracted, affecting work quality and personal safety. For example, when measuring high-voltage equipment, it is very easy to cause dangerous situations such as electric shock to the hand holding the simple test pen, and it is unsafe to use. O...

Troublesome to use, affecting work efficiency, and easily causing distraction, affecting work quality and personal safety

For example, when measuring equipment with high voltage, it is very easy to cause dangerous situations such as electric shock to the hand holding the simple test pen, which is unsafe to use

Or when measuring an integrated circuit block, due to the dense contacts, when people check the measurement gear on the measuring equipment, it is easy to cause instability in holding the pen, and it is easy to touch the adjacent contacts and cause the components to burn out. Meet the tester's requirements
