METER BATTERY LIFE
The power consumption of the
HI 9819X
multiparameter systems are dependent
on two things:
1. The measurement system configuration (sensor configuration)
2. The meter configuration (logging interval and backlight use)
The following table estimates the meter’s battery life connected to a
HI 769819X
probe with backlight off. (
Note:
backlighting use consume the most power).
The table variables, battery selection and parameter selection.
