How to connect the wires to the multimeter with your own hands

Wires for a multimeter are an integral part of the device, which performs its function when working with electrical appliances. Over time, these parts tend to fail. Accordingly, it is time to acquire new ones. It is important here not to make a mistake with the choice and correctly connect to the device.

Purpose and types of wires for the multimeter

The conductors that lead to the probes play a large role in the proper testing of any electrical appliance. However, if the contact is broken, the device is not able to accurately measure the available voltage and determine the operability of a particular device.

Usually this part comes complete with a multimeter, but it is better to have a supply of conductors in case of major creases. Most of them have PVC insulation, which begins to crack with prolonged use. Often these parts are universal, therefore suitable for most models of meters.

Conductors can be rigid (in a rubber sheath) and elastic (in silicone). The latter option is considered the most practical, as it can be easily twisted and any other type of deformation. Such parts are considered reliable and are easy to use even during operation in any conditions.

Conductors in rigid insulation are more suitable for voltage tapping in places where there is little free space. Rubber parts are considered safe because they do not allow electricity to pass through. Suitable in the event that a breakdown on the case is formed in the tested electrical appliance.

Even if the multimeter is equipped with new wires and probes, safety precautions must be observed - wear rubber gloves during operation.

How to change conductors yourself

Although the wires are thin, they are easy to replace and repair.

1. We disassemble the probes and solder the joints, remove the old wire.
2. We take a new one and clean its insulation, solder to the inner end of the probe.
3. We cut a small part of the insulation to the plug and solder it, forming a protection for the contact made.
4. You can use it - the multimeter works.

It is better to replace the wires for the multimeter with your own hands in a room with little humidity, otherwise there is a risk of contact oxidation.

Types of probes

Probes, like conductors, are one of the main parts of a measuring device. With their help, it is possible to accurately determine the contact, analyze the presence of voltage and leakage. They are always included. There are several types of designs.

Universal

In these devices, PVC conductors are provided, which in the heat have the property of cracking. The tips themselves are made of stainless steel. They come with a set of additional nozzles. Experienced electricians believe that these parts are unreliable, since they quickly lose contact with the conductor.

Branded

The probes have wires with improved flexibility. Tips have excellent sealing, rubber handles, so it’s convenient to work with them. On such parts, special caps are provided that create protection against dust and moisture.

For SMD mounting

Devices are convenient to connect. They are used for periodic measurements during installation type SMD. The tips have the shape of a needle, equipped with protective caps. Using probes, it is possible to pierce the insulation of the cable, as well as to clean the solder mask on the boards and other surfaces.

Crocodiles

Also considered convenient for electrical work. They are much more effective than sharp electrodes, capable of preventing short circuit during operation. The sizes of such probes usually vary. Parts must be in a dielectric sheath.

How to make homemade probes

Many amateur electricians prefer to make probes on their own. To do this, you need a small list of available tools and instruments, as well as an understanding of how to connect a multimeter for measuring voltage to existing parts.

Standard probes

The simplest tips are made from parts that are on the farm.

1. We take two fountain pens and two darts.
2. Fountain pens unwind and remove the rods.
3. Instead, we put dart tips in the body.
4. Next, you need to warm up the handle and insert the solder inside.
5. Following the wire passes through the entire handle.
6. If you notice that the tip hangs a little, it can be glued with a glue gun or heated plastic.

It remains only to cool the homemade product and you can connect to a working multimeter.

It is better to use two identical pens. This will create convenience for both hands while working with the probes.

Insulation puncture probes

If you need to make the probes ultra-thin, you will need ordinary sewing needles and pencils (with the replacement of the stylus). However, these products are considered very dangerous and require accuracy during use.

1. We take out the remaining rods from the pencil case.
2. To the needles you need to connect the wires that are in contact with the sockets of the multimeter.
3. We insert the needles in the center of the pencil and sit on the glue.
4. We solder the finished plugs to the wires so that there are no kinks.
5. Next, you need to put heat-shrink tubing on the outlet openings of the pencils, threading a wire through them.
6. For safety, we put silicone caps on the ends of the needles.

Also, probes for a multimeter can be made with a stock of various nozzles, for example, terminals and clamps. However, this will require special adapters.

Probe Cap Options

Separate caps for the tips of the contacts of the multimeter can be purchased at the radio store. Often these parts are lost, and storing the tool without them is unacceptable, since there is a high risk of kink. You can use options from improvised means.

1. We take the usual cap from the gel pen, pour the hot glue inside.
2. Be sure to lubricate the probe tip with oil or petroleum jelly.
3. We insert the probe into the product and wait until the adhesive base hardens.
4. Carefully remove the tip and wipe off the grease.

Next, we make the second cap in the same way.

Connecting a multimeter for voltage measurement should only be carried out provided that the instrument is fully operational. Otherwise, the operation of the tester is considered unsafe.
