METER BATTERY LIFE
The power consumption of the HI 9829 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
HI 76X9829
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. Note: When a
HI 7629829
logging probe is connected to a meter, it uses the meter’s power.
