SUNSHINE Digital Measuring Device DT-890N reviews
Product details
Product description
When you don’t know whether a power source is still providing voltage or if a circuit is interrupted, guessing can cost you time and parts. Sunshine dt-890n is a digital multimeter for electrical and electronic measurements, built around a fast-chip processor. I have a table for daily checks, from batteries to circuits. It is addressed to the technician, not the end customer. What do you check with it most often? The first thing to do is the most basic: check if the voltage reaches the point where you think it should. The second is continuity, which tells you in a matter of seconds whether a cable or a circuit is broken. By performing these two checks, you eliminate a significant number of assumptions before you start working on something. During the repair process, the measurement taken before the intervention tells you where you started, and the measurement taken afterward confirms what you have changed. Note the values on the parts that fit, so you have something to compare them to next time. A measuring device is truly useful when you have a reference point, not just a number on the screen.
proper use of probes. Check the probes before each session by touching them together at the continuity point. Cracked wires at the base of the plug are a common cause of inaccurate measurements. The probe with its bent tip slides off the pad and scratches the protective coating on the board. Choose the scale and position of the switch before touching the circuit, not while holding the probes against the board. Do not measure resistance on a live circuit, as the result will be meaningless. The most common mistake that ruins a multimeter is connecting the cable to the wrong terminal.
maintenance and storage. Keep the device in a dry place, with the switch in the off position, so you don’t waste battery power. If you know you won’t be using it for weeks, take the battery out
otherwise, you risk it leaking into the compartment. Wipe the casing with a dry cloth, without using any solvents on the screen. The cables are loosely arranged in a wide loop, not tightly wrapped around the device. Repeatedly inserting the needle in the same spot will tear the thread inside, and the defect will not be visible from the outside. When the readings start to fluctuate for no apparent reason, try other probes first before suspecting a problem with the device. In short.
