Range LEDs:
one of these LEDs indicates corresponding measuring range of the
output signal. If the LED is blinking (1 s ON – 1s OFF)
A1179/A1257/A1395 detect overrange event at the currently selected
range. With pressing the KEY one can reset overrange detection. If all
Range LEDs are OFF it indicates power off the A1179/A1257/A1395.
Power LED:
OFF – normal operation
Blinking (1 s ON – 1s OFF) – low battery indication, the battery is too
weak for correct measurement results.
ON – The battery cells are charged.
KEY:
Turns the A1179/A1257/A1395 ON, change the measuring range, reset
overrange detection, if held in for more then 3 seconds it turns the
A1179/A1257/A1395 module OFF.
See detailed description of A1179/A1257/A1395 operating states in chapter 6.2.1 and
6.2.2.
