When the internal battery falls below a certain threshold, the device triggers this warning to prevent inaccurate readings.<br><br>​How to Fix It<br><br>​Since the GD128PLUS is a rechargeable model, <br><br>you should take the following steps:<br><br>​Charge the Device: Connect the multimeter to a standard USB charger using the charging port (usually located at the bottom or side).<br><br>​Check the Cable: Ensure you are using a functional USB-C cable.<br><br>​Wait for Full Charge: Let it charge until the battery indicator on the screen shows it is full or the charging light changes color.<br><br>​Why you shouldn't ignore it<br><br>​Using a multimeter with a low battery can lead to "ghost" readings or significantly higher/lower values than what is actually present in a circuit. For safety reasons, especially when measuring high voltage, it's best to wait until it's fully charged.<br><br>​Are you having trouble getting it to take a charge, or did this pop up suddenly while you were working?</p>
