Checking the Power Remaining in the NiCad Battery Pack
You can use the POWER.EXE utility to check the power remaining in the
reader's NiCad battery pack. To display the current power status, type this
command at the DOS prompt and press
power
Or scan this bar code:
*POWER*
*POWER*
The Power Management Status screen appears similar to this example:
These fields help you estimate the power left in the NiCad battery pack:
AC Line Status Tells you if external power is attached to the reader. ONLINE
means the reader is using an external power supply. OFFLINE means the
reader is using the NiCad battery pack for power.
Battery Status Tells you if the NiCad battery pack is high, low, or charging.
High power means the battery pack has more than 50% power remaining. Low
power means there is less than 50% power remaining.
Battery Life (%) Gives you an estimate of the amount of power remaining in
the NiCad battery pack. This estimate is accurate to ± 10%. For example, if the
battery life is at 20%, the battery pack is getting low and you need to replace it
soon. The accuracy of the estimate depends upon variables such as the
temperature, use, and age of the battery pack. When the AC Line Status is
ONLINE, the Battery Life (%) is always 100%, even if the battery pack is not
fully charged.
You may find that POWER.EXE performs differently for each battery pack. For
example, you may find that one battery pack uses power at a faster rate and
reaches 20% battery life sooner than a new battery pack. For a detailed
description of POWER.EXE, see Appendix D, "Software Utility Reference."
Note: You can also use the IRL FP command to determine the power remaining in the
reader's NiCad battery pack. For help, see the IRL Programming Reference Manual.
