Use this section if an error message stating “only 6 slots may be occupied by modules” is
displayed or if the RIGHTMOST LED on the Power Supply assembly is flashing.
 If the message “only 6 slots may be occupied by modules” is displayed, check the rack
connected does not have too many modules plugged into it.
 Disconnect rack to see if LED stops flashing and remains on continuously, and/or the
error message goes away. If a faulty rack is identified, reconnect it, and remove the
parameter modules from it one at a time to see if a parameter module is causing the
problem. If the LED stops flashing when a parameter module is removed, and/or the error
message goes away, replace the parameter module. If all of the parameter modules are
removed and the symptoms do not change, replace the rack.

Use this section when the battery or battery charger circuit are suspected as faulty. For more
information refer to “Chapter 8 Testing & Maintaining the Agilent V24/V26 Series”. Perform
the following with the power switch off.
 Connect the Model V24CT/V26CT to an AC power source. Observe that the leftmost
LED is illuminated. If it is not, refer to “Blown Fuses (Model V24CT/V26CT)” on
page 11.
The next procedure requires the battery charger to be in state 2 of the charging cycle. With
discharged batteries, it takes approximately one-and-a-half hours to achieve state 2. With
90% charged batteries, state 2 can be achieved in two minutes.
Do not remove the display assembly with batteries installed. Removing the display assembly
with the batteries installed can short the battery contacts together and damage the instrument.
 Measure the battery open circuit voltage by performing the following steps:
D Remove the batteries. see “Removing the Lead Acid Batteries” on page 9-5.
E Remove the display assembly.
 Insert batteries. Press the power on switch to turn the monitor on. If 90% charged
batteries are used, the charger enters state 2 in about 2 minutes. If discharged batteries are
used, it will take about one-and-a-half hours to enter state 2. If discharged batteries are
being used, observe the LEDs on the front panel go through a sequence as indicated by
the following table. If no indicator lights appear on the front panel, see Step 5 on 3-16.
