Troubleshooting
Your battery pack is built to provide dependable service during the
service life of the ni-cad batteries. However, if you experience a
problem, desire additional information, or wish to order parts,
Hewlett-Packard’ s worldwide sales and service organization is ready to
provide the support you need.
Basic Troubleshooting
If the battery pack does not work, follow these steps to determine the
cause and resolve the problem:
1. Make sure the analyzer works with ac power. If it does not, follow
the troubleshooting procedures in the spectrum analyzer user’s
guide.
2. If the spectrum analyzer operates on ac power, but not on dc power:
a. Check all of your connections. Is the dc adapter firmly in place?
Are the battery contacts aligned with the dc adapter?
b. Check the 30 A 32 Vdc fuse on the spectrum analyzer. Replace it
if it is blown. (Refer to Figure 3-2.)
3. Make sure that the battery pack is taking a charge from the charger
power supply. Follow the recharging procedure. Usually batteries
near the end of their life will still take a partial charge. If there is no
charge at all, you may need to replace the charger power supply or
the battery pack.
If you are not sure whether the cause of failure is the battery pack or
the charger power supply, follow the troubleshooting procedures
below, or send your battery pack and charger power supply to a
service center for diagnosis. Sending both the battery pack and the
charger power supply will ensure a complete analysis.
Troubleshooting the Battery Pack and the 24 Vdc
Charger Power Supply
Follow these steps to determine whether the battery pack or the
charger power supply is defective:
1. Check the charger power supply for 24 Vdc ±10 % by measuring its
voltage under load with an autoranging multimeter.
Refer to Figure 3-1 when performing the following steps:
20Chapter 3
Figure 3-1Charger Supply Load Test Fixture
Troubleshooting
Troubleshooting
a. Strip the ends of two four-inch pieces of 16 AWG wire, one white
and one black.
b. Solder one end of the black wire to the negative terminal (center
solder lug) of a 2.5 mm male barrel jack (HP part number
1252-5866), and one end of the white wire to the positive terminal
(refer to Figure 3-1). Leave the third terminal of the male barrel
connector unconnected.
c. Plug the two wires from the barrel jack into the terminals of a
dual banana plug (HP part number 1251-0005) and plug this into
the multimeter.
d. Solder together 3 pairs of 20 Ω 20 W resistors (HP part number
0811-1656) in parallel to create the 13.3 Ω 120 W equivalent
circuit shown in Figure 3-1.
e. Connect this 13.3 Ω circuit to the lead terminals of a second dual
banana plug and plug this into the first dual banana plug.
f. Plug the charger power supply’s barrel plug into the barrel jack.
Chapter 321
T roubleshooting
Tr oubleshooting
• If a voltage of 24 Vdc ±10 % is not present, it indicates that the
charger power supply is defective. Avoid leaving the charger
power supply connected for more than 1 or 2 minutes since the
resistors get very hot.
WARNINGThe resistors will get very hot. Handle with care.
2. If the correct charger power supply voltage (24 Vdc ±10 %) is
present, plug the charger power supply into the battery pack and
ensure that the red LED flashes, then remains on.
NOTEThe red LED should turn on and the battery should charge initially
even if the battery pack is fully charged.
If the green LED turns on immediately, this indicates a defective
battery pack. If the red LED continues blinking, this indicates that
the battery pack voltage is below 16 Vdc. The battery will charge in
trickle mode until this condition no longer exists. If this condition
continues indefinitely, this also indicates a defective battery pack.
3. If the red LED flashed and then remained on, as expected, confirm
that the battery charges correctly by probing the battery pack
contacts with the multimeter. The charger power supply will start
charging the battery initially even if the battery is fully charged. The
voltage should gradually increase, indicating that the battery is
charging. If the voltage does not increase by several hundredths of a
volt over a period of 1 to 2 minutes, this indicates that the battery is
not charging properly. Y ou may wish to retry the test by unplugging
and then plugging in the charger power supply again. If the battery
still does not charge, unplug the charger power supply and replace it
with a known good charger power supply and repeat the test. If the
battery charges, this indicates that the original charger power
supply is defective. If the battery does not charge with a new
charger power supply, this indicates that the battery pack is
defective.
NOTEBoth LEDs will be lit if the internal temperature of the battery pack is
above 55 °C or below 10 °C.
4. If all three of these tests pass, it indicates that the charger power
supply and the battery pack are both working.
NOTEDefective battery packs should be discarded according to individual
country’s requirements.
