Initial Setup
Charging and/or Replacing Batteries
The PM880 is powered by a rechargeable NiMH battery pack.
While you can install or remove these batteries in hazardous
areas, you must recharge them
only in general-purpose areas
. For
optimum performance, these batteries require a minimum of
maintenance.
Charging the Batteries
When you receive the PM880, you will need to initially charge
the batteries. The batteries must be charged up to 4 to 5 hours to
receive the maximum charge, until the red LED goes out. When
fully charged, the batteries provide 16 to 24 hours of continuous
operation, depending on the probe type and PM880 usage. An
internal battery gauge indicates the remaining power in the
batteries.
To charge the batteries, simply plug the batteries into the battery
charger and be sure the charger is connected to AC power. When
the charger is plugged into line voltage (as signaled by an amber
power light on the charger), it automatically charges the batteries.
Once the batteries are installed and the PM880 is running, the
Battery icon in the upper right corner of the screen indicates
battery status (as shown in Table 2-1 below).
