• When the icon appears at the upper left of the LCD, it’s time to replace the “9V” battery that powers the 8 instrument (although measurements will remain valid for several hours after the icon first appears). To replace the battery, follow the instructions on page 4 of the instruction manual.
• Do not operate the MMD3E in the presence of flammable or explosive gases.
• Be careful not to stab yourself with the extremely sharp test pins.
• Replace the pin cap and black rubber protection sleeves after making measurements for safety reasons and to avoid bending or dulling the pins.
• After subjecting the meter to a large change in ambient temperature, wait at least 30 minutes before making measurements to guarantee the accuracy of readings.
• Remove the battery when storing the unit or when you do not expect to use it for an extended period of time (months rather than weeks).
