2.3. Control keyboard

2.3.1. Yellow key

When this yellow key is pressed, a high voltage is generated for
insulation testing. However, if a voltage greater than 25 V has
been detected, no insulation testing is allowed and the key
becomes inactive.
In all cases, this key is only active for as long as it is pressed,
except in the TIMER mode specific to the C.A 6525 (first press
= activation, second press = deactivation).

2.3.2. ALARM key (C.A 6523 and C.A 6525)

The ALARM key can be used to activate/deactivate the alarm
thresholds during insulation, resistance and continuity
measurements.
When associated with the
program the values of these thresholds.
2.3.3. Key
When programming the alarm thresholds, the key
the following elements flash in succession :
the measurement unit digit (if there is one),
the thousands digit,
the hundreds digit,
the tens digit,
the units digit,
the decimal separators,
the type of threshold (upper or lower),
and it then returns to the measurement units.
