Meter automatically shuts off after 5 minutes after the last key command. This feature can be disabled while reading in continuous read mode.
One-touch calibration
The meter’s one-touch auto-calibration procedure uses only one button to activate the mode. The unit will prompt and confirm offset and slope point calibration.
