3.9.2 Time between charges
This is at least 8 hours with back-lighting on and at
least 40 hours with the screen-saver activated
(display unit off) when the storage batteries supplied
with the instrument are used.
3.9.3 Recharging of the storage batteries
See also § 12.2, on page 39. The storage batteries
are recharged using the mains power unit supplied
with the instrument. It is connected to the C.A 8230
using the jack (Figure 3, item 1). Use only the mains
power unit supplied with the equipment.
With fully discharged storage batteries, the charging
time is approximately four hours. Once the battery is
recharged, the instrument uses mains power and
does not discharge the battery.
Note: when the mains power unit is connected, the
orange indicator (Figure 1, item 8) lights.
3.9.4 Changing the storage batteries
When you change the storage batteries, you must
disconnect the C.A 8230 from mains and from the
network being measured; the instrument is then no
longer supplied by any voltage source. The C.A
8230 preserves the timestamp settings for
approximately 1 minute.
3.9.5 Storage batteries
The C.A 8230 is powered by six rechargeable NiMH
storage batteries (Figure 4, item 1) in AA format
(LR6 - NEDA 15) having a capacity of at least 1800
mAh. At least 8 hours of self-contained operation
with the screen on is ensured. If the screen is off
(standby mode during an alarm or recording
campaign), at least 40 hours of self-contained
operation are ensured.
The storage batteries can be reached, from the
back of the C.A 8230, after turning the "quarter turn"
lock (Figure 4, item 2) anti-clockwise; use a coin
(Figure 4, item 3).
Note: with NiCd storage batteries (at least 900
mAh), recharging lasts approximately 1h30 and a
full charge allows self-contained operation for 4
hours (screen on) or 20 hours (screen off).

3.9.6 Operation on mains power
The presence of the storage batteries is not
essential for operation on mains power. However,
there is a risk of losing data if the mains power is
disconnected during recording, for example.
3.10 Prop
A retractable prop (Figure 4, item 4) on the back of
the C.A 8230 holds the instrument in position 30°
from the horizontal.
