The invention discloses a universal meter measuring gear warning system and solves the problem that measuring gears are liable to be used falsely due to the absence of prompts in a universal meter usage process. The universal meter measuring gear warning system is characterized in that a red meter pen capacitive touch induction microswitch (3) is arranged on a pen body of a red meter pen (1); a universal meter (14) is provided with a direct-current power supply (12), a flashing prompting light emitting diode (9), a voice prompting device (10), a warning circuit switch (11) and a red meter pen touch induction connection jack (7); one end of the red meter pen capacitive touch induction microswitch (3) is electrically connected with an A end of a red meter pen touch induction connection plug (5), and the other end of is electrically connected with a B end of the red meter pen touch induction connection plug (5); and the red meter pen capacitive touch induction microswitch (3) is electrically connected with the flashing prompting light emitting diode (9) and the voice prompting device (10). Safety of a measuring meter and a measured circuit is ensured.
