ES269
6000 Counts Intelligent Auto-Function DMM IC
Auto power off mode (APO)
Idle Time selection
ES269 has a default auto power-off function. If the meter is idle for more than the given Idle Time, it
automatically turns the power off. The idle time can be selected by pin ‘CLAMPAPO’. See Table 13 for
details.
Sleep output
The meter enters sleep mode after auto power-off or push SEL key to last for 2s. The SLEEP pin asserts
low (-3V) in the sleep mode, and asserts high (+3V, not 0V) after re-power on.
Re-power on
After auto power-off is active, press SEL key over 2 seconds can turn on the meter again.
Hazardous Voltage Indication
The ES269 could provide the AC/DC hazardous voltage indication for voltage/resistor/ diode modes.
Of course, the indication could support LCD symbol / LED (ALARM pin) /Buzzer driving
simultaneously. Especially ES269 could detect the AC voltage in DCV mode and detects the DC
voltage in ACV mode. It means if not proper AC or DC voltage signal exists on the device under test
when DCV or ACV measurement mode is set, the HV indication will be active
