BATTERY
- A built-in rechargable NiMH battery supplies power for 18 hours continuous operation when fully
charged.
- Display brightness is adjustable to conserve power.
- State of charge is shown for normal use, sleep mode and charging.
- When switched OFF with the AC power module connected the flashing battery indicates charging,
solid battery shows fully charged.
- The PF D550 will switch off automatically when the battery is fully discharged.
- Full charge requires approximately 6 hours charging.
- Sleep mode extends battery life for long term data logging. Maximum log time is 18 days at 5 minute
sample rate.
