Test port and spectrometer pressure with alphanumeric indication on
the LCD display.
Sensitivity optimized design, header mounted ion source with dual
thoria-coated iridium filament, a high sensitivity, wide dynamic range
preamplifier, and vacuum gauge.
Microprocessor-controlled valve operation provides automatic system
cycling.
A valve system design that completely protects the high vacuum
system under test against pressure surge and power interruption.
Optional
This provides:
RF communication between the VS leak detector (with base sta-
❑
tion or host) and the Wireless Remote unit from a distance up to
100 m (300 ft).
The ability to enter the VS leak detector unit into Test and Hold
❑
modes from the Wireless Remote unit's keypad.
The ability to read the VS leak detector's leak rate in a linear and
❑
logarithmic bar graph format with a numeric range indicator and
System status in alphanumeric format on the Wireless Remote
unit's LCD display.
Configuration up to 10 different VS leak detector unit's for wireless
❑
control by toggling through a MAC address list using one Wireless
Remote unit
This provides 12 outputs and 8 inputs lines, optically isolated, to
control the VS leak detector using an external PLC via a 25-pin DB25
female connector and a user-provided parallel cable.
