Resistance (C.a 6523 And C.a 6525); Special Functions; Start/Stop; Automatic Shutdown - Chauvin Arnoux C.A 6521 Notice De Fonctionnement

Specific remark concerning the C.A 6521 :
In continuity mode, a lower threshold of 2 Ω is constantly active.
However, the buzzer can be deactivated by pressing the yellow
key.
3.3

Resistance (C.A 6523 and C.A 6525)

Resistance measurement corresponds to the 400 kΩ position
of the switch on the C.A 6523 or C.A 6525.
The Ω symbol is displayed with the k symbol if necessary. The
measurement is indicated on the digital measurement display.
The instrument indicates if the value measured is outside
its measurement range. If the resistance is greater than
400 kΩ, the OL symbol is displayed on the digital measurement
display.
Resistance measurements shall be performed on idle
circuits.
A programmed threshold may trigger an alarm (see § 4.5).

4. SPECIAL FUNCTIONS

4.1. Start/stop

When you move the switch from the OFF position to one of the
active positions, the battery voltage is applied to the circuit. The
instrument starts up and all the display segments light up at the
same time for 1 second. All the segments then go dark except,
for 2 seconds, the , and symbols which delimit the
size of the bargraph. The bargraph indicates the battery charge
life and the digital measurement display which indicates the
charge life available (0 to 100%) for a battery voltage varying
from 6.7 to 10 V.
The instrument can be shut down at any time by moving the
switch to OFF, which cuts off the battery power supply to the
whole instrument.
.

4.2. Automatic shutdown

After 5 minutes without any activity by the user on the instrument
(key press on the keyboard or on the yellow key on the remote
control probe or turn of the rotary switch), the instrument shuts
down automatically. It is then on standby. When this is the case,
to start up the instrument again, all you have to do is press one
of the keys, turn the switch or press the yellow key on the remote
control probe of the C.A 6523 or C.A 6525.
The automatic switch-off is inhibited during continuity
testing as long as the measurement being made varies between
a value (between 0 W and 20 W) and OL (which means that
measurement is in progress).
On the C.A 6525, in TIMER mode (see § 4.7), the five minutes
before automatic shutdown only begin at the end of the maximum
15-minute measurement period.
