Warnings continued on page 3. SKU For replacement parts, please call Page Page 3 Any part that is damaged should be properly repaired or replaced by a qualified technician. Do not use the tool if any switch does not operate properly.

Page 4: Operation Do not test voltage on AC circuits higher than volts. Do not test voltage on DC circuits higher than volts. Do not test current on circuits higher than 10 amps. Switch the Multimeter ON. Connect the red probe to the anode of the diode and the black to the cathode. Our household power voltage is a typical alternating current AC , while that from a battery is direct current DC. There are also the ports where you plug in the probes and a display screen on the Cen-Tech digital multimeter.

Note that there is a limit to Voltage you can measure on most Cen-Tech digital circuit checkers; it falls within mV to V.

In simple terms, a digital multimeter is a type of testing tool which you can use to test several electrical values like current, Resistance and Voltage. One advantage the digital multimeter has over the analog multimeter is that it has a more accurate and readable digital screen.

So, when using a digital multimeter, you can eliminate errors due to parallax. Moreover, in modern digital multimeter you will find in it a type of computer system whicj will offer you features that makes measuring electrical values easier, such as graphical representation, auto polarity, auto-ranging.

Some modern digital multimeter gives you the flexibility to interface it with a personal computer via USB, or any other instrument bus. This interface allows you to record the measurements made on your personal computer. Different Cen-Tech multimeter comes with several features of which you will find very helpful in different scenarios. Here are the most common features you are most likely to find in a digital Cen-Tech multimeter:.

Cen-Tech modern digital multimeter features a removable battery, mostly a 9V battery. A digital Cen-Tech multimeter cannot function without a battery. Some Cen-Tech digital multimeters have a backlit, powered by the battery. Fuse is another crucial component of the Cen-Tech upgraded digital multimeter.

We know a fuse is set to break when a certain level of current is exceeded, and that is what a fuse does in the Cen-Tech digital multimeter. The fuse will also cut at an instantaneous high current, thereby protecting the Cen-Tech from damage. Another feature of the Cen-Tech digital multimeter is the digital screen. Irrespective of what you want to measure, be it AC or DC, use the knob to set it appropriately before any test.

Be sure to use the right electrical value for the proper testing to prevent burns or electric shocks. Most Cen-Tech high tech multimeters come with multiple ports where you can plug in the probes. The flexibility of the ports allows you to be able to plug in different types of Probes. Often, you would find two or more ports for the black and red wire. With the auto-ranging feature of the Cen-Tech digital multimeter, the multimeter will always selects the correct range for the quantity under test.

For instance, if your Cen-Tech digital circuit checker is a four-digit multimeter, on measuring an electrical value it would automatically select an appropriate range to display. So if you measure a voltage rather than the multimeter displaying 0. Safety is an essential part of using a multimeter. You need to take into consideration that electricity can be hazardous, and if care is not taken, it can lead to severe injuries or even death.

So, when using a Cen-Tech digital multimeter to check for Voltage, ensure you observe the general safety precaution. Furthermore, inspect the multimeter to ensure it is in good working condition such as the probe especially. Ensure the probes are well insulated so that you would not come in contact with the current directly.

Lastly, make sure you use the right function of the multimeter for the right purpose. To set the function of the multimeter to measure an electrical value, use the selection knob.

In this case, where we would measure Voltage, turn the selection knob to either AC voltage or DC voltage as the case may be.
