6. SETTINGS and SERVICE MODE MENU

By pressing at the same time right and central keys, user can enter the SETTINGS and SERVICE
MODE, called briefly SETTINGS, where it is possible to change some of the working parameters
and obtain useful information about the operation of the device.
Note: All pre-set values are stored even if the device is switched off.
Here in the following all the items and their description.

Vout Set Point

This is the working voltage of the IP. This parameter can be adjusted by the user according to his
needs.
The factory default value is 5kV. To change this value, enter in SETTINGS menu by pressing the
two buttons together for 5 seconds, press the ENTER key and then just press key or . The
range of adjustment is 1÷6 kV with a precision within 1%. Save the new value by pressing the
ENTER key. Exit to SETTING menu by pressing the two buttons together for 5 seconds.
Then the output voltage keeps this value with accuracy ±50 V providing that the output power does
not overcome maximum possible value of the source.

Vout Ramp Intv

This is the ramp time, that is the time that is required to linearly increase the high voltage from 0 V
to Vout Set Point. The Vout Ramp Time value is adjustable by the user according to his needs in
the range 1÷60 seconds.

Conversion Rate

Magnitude of the converting constant used to estimate the local pressure from the value of current.
It is possible to change this constant in the range 1 to 200 A/Torr. Resulting readings of pressure in
different units will be influenced as well. The factory default value is 65 A/Torr. This value is valid
for standard operation at 5kV of NEXTorr D100-5, D200-5, D300-5 and D500-5 pumps. In case of
NEXTorr D1000-10 and D2000-10 this parameter must be set at 150 A/Torr.

SW1 Mode and SW1 Thr.

The comparison level for the overcurrent protection circuits (SW1) and the additional two
comparators (SW2 and SW3) have been introduced in Sec. 4.3.
SW1 Mode allows to switch on and off SW1: possible values ON / OFF default OFF.
SW1 Thr. is the threshold value for SW1 comparator: can be changed from 0nA to 99mA.

SW2 Mode and SW2 Min Thr. and SW2 Max Thr.

SW2 Mode allows to switch on and off SW2: possible values SIMPLE / WINDOW / OFF
SW2 Min Thr. is the threshold used by SIMPLE mode and lower hysteresis value in case of
WINDOW mode. Can be changed from 0nA to 99mA
SW2 Max Thr. is the upper hysteresis value in WINDOW mode. Can be changed from 0nA to
99mA (ignored in SIMPLE mode).
