Review on 🔧 Bluetooth Clamp Multimeter AP-570C-APP - 4000 Counts Digital Clamp Meter for DC/AC Voltage & Current, Resistance, Temperature, Frequency, Duty Cycle by Carlos Henley

Pro: App data format is user-friendly and contains relevant data, such as pattern serial number, resistance value, unit of measurement. in kΩ and time stamp (TS) for each serial number. It also shows Max/Avg/Min and TS Max/Min values. Cons: This is why I will be returning this product: On more than one occasion the data log disappears after taking some samples and shows this product. unreliable and unusable for the purpose I bought it for. That should not happen. It seems that the number of samples that can be registered is limited. When this limit is reached, data logging should hang/stop and not go away. Apparently, the data is stored either in the application or in the counter, and the data must be stored in the mobile phone's memory. I could easily view more than 29,000 samples during a single monitoring session. Another reason I come back is that the Bluetooth connection between my Android smartphone and your multimeter is not reliable - sometimes it takes multiple connection attempts; when it connects, it disconnects; If I move the phone less than 50 feet, the connection drops. Need a better bluetooth xceiver.
