Insulation < 70 kΩ
2.2.3 Digital display
BAT Batteries low – must be changed
OL Range exceeded
- - - Insulation < 10 kΩ at 50 V, < 20 kΩ at 100 V,
< 50 kΩ at 250 V, < 100 kΩ at 500 V
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. The instrument remains in voltage
measurement mode.
2.3.2 ALARM key
The ALARM key can be used to activate/deactivate the alarm
thresholds during insulation and resistance measurements.
When associated with the
program the values of these thresholds.
2.3.3 Key
This key can be used to program:
The alarm thresholds (with the ALARM key)
By pressing the
flash, successively:
- 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.
The capacitance per unit length in nF/km (with the
on the CA 6531).
By pressing the
flash, successively:
- the tens digit,
- the units digit,
- and it then returns to the tens digit.
