ES269
6000 Counts Intelligent Auto-Function DMM IC
Low Battery Voltage Detection
ES269 provides a voltage detection input (pin 95:
BAT9
) for non-3V battery application. When
BAT9
is
less than
VRH
terminal voltage, the LCD segment of low battery will appear. For 3V battery
application, pull
BAT9
to AGND directly and the same detection will be made when V- is less than
2.3V typ.. When the Low battery status lasts for 10 seconds, the LCD segment of low battery will be
blinking. When the symbol is blinking for 20 seconds, the operation of meter will be inhibited and
LCD panel will show “ Lo.bt”. In this case, it is suggested to replace a new battery immediately. After
“Lo.bt” appears and lasts for 60 seconds, ES269 will enter to auto power off mode.
