5.4.1 Configuration of the test parameters for RAMP#1 mode
a. By cyclically pressing the SET/DISPLAY MEM key, it is possible to select the
following parameters:
• Minimum value of the insulation (MIN) in a range between 0,01M - MAX
• Maximum value of the insulation (MAX) in a range between (MIN) - 10T
• Value of time interval ΔT, in which the test voltage passes from 0V to the set
value V1
• Value of the test voltage V1 in a range between 100V - 5000V (can be set in
steps of 25V up to 1000V and in steps of 50V from 1000V to 5000V)
• Value of time T1 in which the test voltage V1 is applied, in a range between
(00min:05sec) - (99min:59 sec)
• Number N of cycles in which the ramp is repeated, in a range between 1 - 255
(N=1 indicates 1 only test without repetitions)
b. Press the arrow keys to change the value of the parameters (a long pressing of the
keys allows a rapid change of the values)
c. Press the MODE/CLEAR SMOOTH key to remove the limit values set for the
parameters. The display shows the message "no" to indicate that there is no limit set.
When setting the value of the time interval ΔT, of the test voltage V1, of time T1 and
of the number N of cycles, by pressing the MODE/CLEAR SMOOTH key, the default
values are set (respectively 30sec, 1000V, 1min, 1 cycle)
d. After setting, press the SAVE key to save the changes made or press the
ESC/RECALL MEM key to exit without saving and return to the previous screen
5.4.2 Configuration of the test parameters for RAMP#2 mode
a. By cyclically pressing the SET/DISPLAY MEM key, it is possible to select the
following parameters:
• Minimum value of the insulation (MIN) in a range between 0.01M - MAX
• maximum value of the insulation (MAX) in a range between (MIN) - 10T
• Value of the starting voltage V0 in a range between 100V - 1000V (can be set in
steps of 25V)
• Value of time T0 in which the test voltage V0 is applied, in a range between
(00min:05sec) - (99min:59 sec)
• Value of time interval ΔT in which the test voltage passes from the set value V0 to
the set value V1, in a range between (00min:05sec) - (99min:59 sec);
• Value of the test voltage V1 in a range between 1000V - 5000V (can be set in
steps of 50V)
• Number N of cycles in which the ramp is repeated, in a range between 1 - 255
(N=1 indicates 1 only test without repetitions).
b. Press the arrow keys to change the value of the parameters (a long pressing of the
keys allows a rapid change of the values).
c. Press the MODE/CLEAR SMOOTH key to remove the limit values set for the
parameters. The display shows the message "no" to indicate that there is no limit set.
When setting the value of voltage V0, of time T0, of time interval ΔT, of voltage V1
and of the number N of cycles, by pressing the MODE/CLEAR SMOOTH key, the
default values are set (respectively 100V, 15sec, 30sec, 1000V, 1 cycle).
d. After setting, press the SAVE key to save the changes made or press the
ESC/RECALL MEM key to exit without saving and return to the previous screen.
