A lit red LED above the test button, when the instrument is not conducting a test, indicates a fault. Do NOT use the instrument if this

If the internal temperature of the instrument exceeds a safe level, the test will be aborted and indicated on the screen. The
temperature must drop before testing can be continued.

A flashing battery icon, showing the current charge level, indicates that the battery is prevented from charging due to the temperature
being out of the allowable charge temperature range, 0 ºC to 40 ºC, or that the battery has failed.
