The unit will turn itself off after 20 minutes (sleep mode). To override
the auto power off function (non-sleep mode), press the “ON/OFF”
button and “MIN/MAX” button simultaneously. After the display

Battery Replacement
Always use a fresh replacement battery of the specified size and type.
Immediately remove the old or weak battery from the meter and
dispose of it in accordance with your local disposal regulations. Batteries
can leak chemicals that corrode electronic circuits. If your meter is not
going to be used for a month or more, remove and store the battery in
a place that will not allow leakage to damage other materials.
To install a new battery, follow these procedures:
1. Remove battery cover, by using a coin.
2. Replace batter with “+” side up. Replace cover.
