Do we offer a meter that will give a voltage reading through non-contact like a current reading?

No, we currently only have non-contact voltage testers, not voltage meters. Any voltage reading would require having the test leads from the meter touching the circuit. Clamping the meter around a conductor with the meter on a voltage setting will not give any reading.

How do I clamp around a single conductor without damaging the power cord?

We offer the E1 lines splitter that isolates both the hot and the neutral conductors safely for the end user to take their measurement. Using this, you can either get a direct reading or a x10 reading for low current applications. This is only rated for up to 10 Amps. Any larger current draws would require making a custom jumper isolating each of the conductors. A professional electrician should be contacted for help doing this.

Do you have alligator clips for the test leads?

Yes, for the GB and Sperry meters RTL-107 is a slide on alligator clip that slides on to the metal tip of the test leads. For a customer looking for Sperry leads with alligator clips, TL42 has removable alligator clips. The alligator clips that come with these leads will not work with any other set of leads because instead of just sliding on the test leads, these ones will screw onto the lead.

Continuity Measurement.

Any multimeter with the ability to test resistance or ohms can measure for continuity. Some meters have an audible buzzer to let you know when you have continuity, while others don’t. You need to keep an eye on the display to watch the reading the tester is giving. Most analog testers you have to watch the screen to see if the needle goes all the way to the right. With the digital meters, some have an audible symbol to let you know if the meter has an audible buzzer or not.

This is the audible continuity buzzer. In most cases, if the reading is under 50 ohms of resistance, the meter will buzz. With other testers, you would just select any of the resistance ranges () and watch the reading you get on the screen. It should be as close to 0.00 as possible to have the best continuity. Most times you will get something between 0.00 and 0.3 on the display because the meter is picking up resistance in the circuit being tested and in the test leads.

WARNING!!! ALWAYS TEST CONTINUITY ON A CIRCUIT THAT IS SHUT OFF. A live circuit will damage the tester and potentially injure the user.

CS61200 On/Off Button Guard

If you find yourself having trouble keeping the CS61200 turned off while in your tool bag. Than this simple fix may be the trick you’ve been looking for. In the below picture you’ll see the CS61200 and you’ll notice something a little different. One of our customers attached two o-rings to the front of the unit guarding the on/off button. This keeps the unit from turning itself on while in your tool bag.


The Hold Function

On many of our Sperry meters there is a hold button that will freeze the screen, holding the information of the last reading you took. When this option is in use, there is a small letter “H” displayed on the screen. This allows you to write down the reading without having to hold the test leads in place.

If you’re having trouble taking readings and the readings on the screen do not change, look for the H. This may be your problem. In other cases it’s due to a low battery, which causes the meter to give faulty readings.
