Configuration of the test parameters for RAMP#3 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);
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 voltage V0, of time T0, of time interval ΔT, of 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 100V, 15sec, 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.

ENABLE/DISABLE OF SMOOTH FUNCTION
1.
With the instrument in normal mode (no SET of parameters), press and hold the
MODE/CLEAR SMOOTH key for approximately 3 seconds. On the display, the
word SMOOTH appears (or disappears, if already displayed). This feature is
suggested with very high capacitance loads presence in order to improve the
readings at display.
4.12
ANOMALOUS SITUATIONS
1.
If, upon pressing the
START/STOP
key, the
voltage at input leads -Rx, +Rx is >
allowable limit voltage, the instrument
gives a long acoustic signal and displays the
screen reported here to the side for 3
seconds. Afterwards, the instrument
returns to the initial screen.
