SYSTEM SPECIFICATIONS
METER BATTERY LIFE
The power consumption of the HI9829 multiparameter system is dependent on three things:
1. The measurement system configuration (probe type, sensor configuration)
2. The meter configuration (logging interval, GPS and backlight use)
3. The battery type (alkaline or rechargeable).
Note: Alkaline batteries have two times the expected life.
The following table estimates the meter’s battery life connected to a HI76X9829 probe with backlight
off. The logging interval only affects meter battery life when GPS Powersave mode is used (units with
GPS).
Note: GPS and backlighting use consume the most power.
The table variables are GPS, battery selection and parameter selection.
When a HI7629829 logging probe is connected to a meter, it uses the meter’s power.
