Medium Frequency user: Once per month usage.
For this type of user, the instrument should be plugged in for a minimum of three (3) hours prior
to use. Otherwise, the instrument can be left unplugged.
Infrequent user: Greater than one month between uses or long term storage.
For this type of user, the instrument should be fully charged and the battery should be
disconnected. Make sure nothing is plugged into the back of the J405, then remove the front 2
screws near the intake and open the instrument. On the front most part of the main circuit board,
there is a black 4 pin connector,
as shown here. Depress the safety
latch on the connector and pull it
out to disconnect the battery.
Close the instrument and replace
the 2 screws in the front of the
instrument. Reverse these steps
to reconnect the battery if the
instrument is going to be used.
The time and date will need to be
reset when the battery is
reconnected for instrument use.
See
for instructions.
If the instrument will be in storage for more than 4 months, it will need to be taken out of storage
and fully charged every 4 months before being placed back in storage. To do so, reconnect the
battery and connect the AC power supply/charger to charge the instrument for a minimum of 3
hours. See
for charging instructions. After charging,
disconnect the battery before returning the instrument to storage. Again, the time and date will
need to be reset if the battery is reconnected so the instrument can be put into service.
Sample data is stored in non-volatile memory and will not be lost or affected when the battery is
disconnected or replaced.
External Battery Power
An optional external battery pack (AZI P/N: 990-0214) is available to power the J405, but it is not
recommended for routine use. The external battery pack should be reserved for sensor
regenerations or sampling when the internal battery is nearly discharged and AC current for
recharging the internal battery pack is unavailable. The external battery pack will not recharge
the J405’s internal battery pack.
The external battery pack is recharged by connecting the J405’s AC power supply/charger
between an AC outlet and the female DIN connector on the external battery pack. The green LED
on the external battery pack will light up during charging of the external battery pack, and then go
out once the external battery pack is fully charged; this takes approximately 4 hours. The red
LED on the external battery pack will only light up if there is a battery fault or error. Should this
occur, call AZI Customer Service at 800-528-7411, 602-470-1414, or e-mail
for additional information. If the AC power supply/charger is connected to the external battery
pack while the external battery pack is connected to the J405, both the J405 and the external
battery pack will be recharged.
