    10. Notes for Measuring and Handling (1) Confirm the type of material being measured. Be sure to check the type of material and select the correct probe type before beginning measurements. (2) Do not damage the probe or get it dirty. Accurate measurement results cannot be obtained if the chip on the tip of the probe is damaged or dirty.

When the batteries become weak, a "BAT" indicator will appear in the display when the power is first turned on or while the tester Caution is in use. Immediately replace the batteries with 4 new size AA alkaline batteries when this indicator is displayed. Please note that calibration adjustments are maintained in the unit's non-volatile memory even when the batteries are exhausted.
