During designing of NP15B special attention was paid to the safety of use and its functionality, through the use of, among others, the function of signaling the presence of dangerous voltage at the terminals of the meter, the buzzer informing about exceeding the preset range, the use of one common fuse in a separate pocket for all current measurement ranges from 600μA to 10 A AC/DC, or the intuitive MENU of the instrument.

Just de-energize the cabinet; open the panel while wearing PPE; and connect the remote modules—voltage modules, current clamps, flexible current loops or thermometers. Now, Pair the module to your phone, then go to the Serial Monitor app and connect it, it will show the voltage on the range depending upon your voltage divider, from 0V to 25V in this case. The B35T+ multimeter is supplied with test leads, a multifunction test socket, a user manual and a K-type thermocouple. Unlike traditional multimeters, Bluetooth multimeters can be supported through software updates to be upgradable even long after they have been manufactured. The unit also has v oice warning supported, which assures measurement safety smart voice-reading accessible 4(1/2)-digit counterparts.The Bluetooth Multimeter is a newly upgraded professional multimeter which as well as showing the data on the large LCD it can do remote operation and measurement through Bluetooth. We have a large factory and professional manufacturing team, and we have first-class design and reliable functions, use of various materials and performance testing. We believe partnering with other likeminded companies is a great way to help each other out and ultimately make products that are better for the end consumer.

With a Bluetooth-enabled multimeter, a smartphone can be used to control the multimeter by simply using the touchscreen. The B35T is an economical multifunction 3 5/6 digit multimeter, datalogger, and temperature meter that offers true RMS reading and Bluetooth (Android + iOS) connectivity for remote measurements. If the item comes direct from a manufacturer, it may be delivered in non-retail packaging, such as a plain or unprinted box or plastic bag. With their Bluetooth interface and the SEFRAM Connect App dedicated to tablets and smartphones (Android or iOS), you can follow your measurements, download in real time, consult the memory, etc.

The problem is that many of them use low-energy BLE and Windows doesn't have a good way to handle it.
