6000 Counts Intelligent Auto-Function DMM IC
EF key function
ES269 supports a non-contact ac voltage measurement, which is called electric field measurement also.
Press EFKEYP less than 1 second to enter EF function. When press it again to exit EF function. The
ADC input is configured from EFin pin vs. SGND. When no or less electric field is detected, the LCD
shows “EF”. If the detector senses electric field, the strength will be showed on LCD by “-“ not digits
type. Level 1(weak) is “-“ and the level 4(strong) is “----“. Additional beeper will be output from
BUZOUT pin. The buzzer frequency depends on the strength of electric field also. The Faster beeper
means the stronger electric field (ac voltage) is sensed. The buzzer can be disabled through
S600VEFSEL pin. See Table 12 and
