Battery Charging
A fully charged battery pack powers the 2020ComboPRO for approximately 6
hours. If the instrument is to be used for more than 6 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 off the 2020ComboPRO before removing the battery pack, you
will reset the instrument and you will lose all logged data and setup parameters.
When the 2020ComboPRO 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 2020ComboPRO 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
2020ComboPRO. Optionally you can use the off-line charger to charge the battery
pack independently of the instrument. See Off-Line Charger on page 79.
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 2020ComboPRO while it is
connected to the AC adapter.
WARNING
The 2020ComboPRO 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 2020ComboPRO is red, the battery is
charging. When the Charge LED turns green, the battery is fully charged.
