    Why is my Hioki 3455 Test Equipment power not turning on?
    • S
      Sharon MontesAug 14, 2025
      If your Hioki Test Equipment is not turning on, several factors could be at play. First, ensure a battery is installed. If one is present, try installing a new battery to rule out low battery power. Verify that the battery polarity is correct. If you're using a battery pack, make sure it's adequately charged. Lastly, confirm that the battery selector switch is in the appropriate position.

    Why does Hioki Test Equipment power fail when measuring insulation resistance?
    • K
      Krystal WattsAug 21, 2025
      Power failure during insulation resistance measurement in Hioki Test Equipment can occur due to several reasons: low battery power (replace with a new battery), an uncharged battery pack (charge the battery pack), or a short-circuited GUARD terminal with the test lead connected to the + terminal (check the connection to the test lead clips).
