  If the built-in battery isn't recharging and the recharge sign isn't showing, check the following: * Ensure the built-in battery switch is set to ON. If it is, you may need to replace the battery pack. * If the battery is fully charged, recharge it when the remaining battery power is low. * Only use the AC adapter supplied with the SJ-210.

  If your SJ-210 fails to power on using its built-in battery (with the AC adapter disconnected), the possible causes are: * The remaining battery voltage is too low, so recharge the battery. * The built-in battery switch is set to OFF, so set the built-in battery switch to ON.

  If the power does not turn off, it might be because the AC adapter is in use and the Auto-sleep function is OFF. Keep holding down the [Esc/Guide] key for more than 3 seconds.

What does 'Cumulative distance is over the limit!' mean for Mitutoyo Measuring Instruments?
- A
  austinsantiagoAug 23, 2025
  The message 'Cumulative distance is over the limit!' indicates that the result of cumulative distance measurement exceeds the display range. The error display is cleared when the cumulative distance is deleted or the measurement range is set to a wider range.

Our unit will only stay on while plugged in (battery symbol in corner shows 3 green bars). The moment you unplug it, it turns off. Is this internal circuitry issue or is the charge symbol lying and the battery is holding no charge?
