Agilent Helium Leak Detector User Manual
Description
Fully automated tuning and calibration using the internal or external calibrated
leak. The fast calibrate feature allows calibration in less than one minute.
Selectable mode background elimination with a unique, patented Autozero<0
feature.
A bar graph (linear or log) indicator displays leak rates automatically; alphanumeric
indication on Touch Panel display. A leak can also trigger an audible alarm
frequency that varies in proportion to the size of the leak, dedicated volume control
and programmable audio threshold. Analog voltage is proportional to the leak rate.
Test port and spectrometer pressure with alphanumeric indication on the Touch
Panel display.
Sensitivity optimized design, header mounted ion source with dual Yitria-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 leak detector (with base station or host) and
the Wireless Remote unit from a distance up to 100 m (300 ft).
• The ability to enter the leak detector unit into Test and Hold modes from the
Wireless Remote unit's keypad.
• The ability to read the 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 Touch Panel display.
• Configuration up to 10 different 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 leak
detector using an external PLC via a 25-pin DB25 female connector and a user-
provided parallel cable.
