Test Leads Comparison

→ Multimeter test lead quality and precision depend largely on the quality and precision of the test clips.

→ We evaluate test leads based on two groups of criteria:

→ A) HANDS-ON measurements – when you hold the test clip or probe in your hand.

→ B) HANDS-OFF measurements – when the test clip or probe is connected to the test point, leaving your hands free for other activities.

→ For both types of measurements, higher scores indicate greater reliability and precision, contributing to the overall performance of the multimeter.

→ The Test Clips Comparison demonstrates significant advantages of the Parrot Clip, based on our evaluation as well as independent evaluations.

TEST Leads Comparison : Alligator Clip, One Hook Clip, Two Hook Clip, Parrot Clip

Multimeter Test Leads use Test clips for better Hands on and Hands Off measurements. For both measurements best scores are a sign for reliability and precision witch is to be added to the performance of the multimeter.  Test Clips Comparison proves great advantages for the Parrot Clip.

We made the Test Leads Comparison for the exiting test clips on the 6 important criteria, 3 Hands-on criteria and 3 Hands-off criteria.
Answering to some Questions like the flowing ones:

1) Direct point measurement comfort and accessibility
a) Is comfortable to you keep the test probe in your hand ?
b) Is possible to point the test probe to a measuring point ?

2) Direct point contact resistance
a) How sharp is the tip of the test clip or test probe ?
b) How is Is the test clip connected to the leads : x) solder, y) through the walls of the clip ( as at the 2 hooks clip ) z) trough the banana plug

3) Signal operator insulation
a) What voltage can be tested if you keep the test probe or clip in your hand ( HANDS – ON ) . Actual standard : IEC 61010
b) What is the between your fingers and the tip of the probe. ( the 2 hook clip keeps your finger far from te test point so is difficult to probe )

4) Connection reliability : Mechanical and at high temperature.
a) is the connection made between 1 metal part and one plastic part ( as at the one hook clip ) , or between 2 metal parts ?

5) Connection resistance
a) is the connection made between 1 metal part and one plastic part ( as at the one hook clip ) , or between 2 metal parts ?
b) How is Is the test clip connected to the leads : x) solder, y) through the walls of the clip ( as at the 2 hooks clip ) z) trough the banana plug

6) Connection comfort and accessibility in narrow places
a) How sharp is the tip of the test clip or test probe ?
b) how easy is to perform the connection
