Battery Charging
A fully charged battery pack powers the 2020ppbPRO for approximately 8 hours. If
the instrument is to be used for more than 8 hours, carry a spare battery pack (Part
No. MX700010 or MX700011). When the first one has been discharged, replace it
with the spare.
NOTE: If you do not turn the 2020ppbPRO off before removing the battery pack, you will
reset the instrument and you will lose all logged data and setup parameters.
When the 2020ppbPRO displays the low battery symbol, the battery pack requires
charging. When the low battery symbol is displayed, you have 30 minutes of
operation left. The 2020ppbPRO will turn itself off before the battery pack becomes
critically low.
WARNING
Do not remove or recharge the battery pack in a hazardous location.
Upon return from field work, charge the battery packs as outlined in Battery
Charging on page 39. Use only the AC adapter specified for use with the
2020ppbPRO. Optionally you can use the off-line charger to charge the battery pack
independently of the instrument. See Off-Line Charger on page 73.
NOTE: You must use the 220 V battery charger (Part No. MX396013) in order to comply
with the requirements of the applicable Council Directives.
If you do not require portable operation, you can use the 2020ppbPRO while it is
connected to the AC adapter.
WARNING
The 2020ppbPRO is not intrinsically safe when connected to an AC adapter.
The AC adapter automatically charges at a high charge rate until the battery pack is
fully charged. It then maintains the full charge with a low continuous charge rate
indefinitely so there is no danger of over-charging.
When the Charge LED on the top of the 2020ppbPRO is red, the battery is charging.
When the Charge LED turns green, the battery is fully charged.
Battery Pack Care
Leaving the 2020ppbPRO for more than 3 months without charging the batteries
may result in the loss of recorded data and setup parameters. If the 2020ppbPRO is
not used for long periods of time, recharge the battery for a few hours every 30 days
