Display is blank on instrument

In the event that the instrument display blank it is important to know that the MA98 instrument utilizes two power down modes to conserve battery life.

Sleep Mode - The instrument has been in an idle state for 5 to 15 minutes. The instrument is ready to measure, however the display is not on. A button press, measurement, power connection (if not connected), or USB connection will wakeup the instrument.

Off Mode - The instrument has been in an idle state for over 15 minutes. The power button must be pressed and held for three seconds to wakeup the instrument before a measurement can be taken. Plugging in the AC adapter will also wake up the instrument from power down mode. Off mode does not occur when the AC adapter is attached to the instrument.
