What to do if my PEAK INSTRUMENTS C-7200 Measuring Instruments has a power failure?
- J
  Julia WeberAug 4, 2025
  If your PEAK INSTRUMENTS Measuring Instruments is experiencing a power failure, there are several potential causes and solutions to consider: * **No electrical outlet supply:** Check the external power source. * **Power cord not plugged:** Ensure the power cord is securely plugged in. * **Internal wiring is loose:** Under the guidance of service personnel, open the housing and re-seat the wire. * **Internal +5 V power supply is not normal:** Under the guidance of service personnel, open the housing and re-seat the cable. * **Socket switch is broken, internal power supply burned, or the motherboard is not working properly:** Please contact the manufacturer or your local dealer.
