Operator Controls & Indicators
An LED bar graph indicating the mantissa of the measured
leak rate of the test object. For a full leak rate reading, this
meter is used in conjunction with the Numeric Display. The
bar graph display is in standard cubic centimeters per second
or in millibar liters per second.
A two-digit alphanumeric display with two separate functions.
During testing, the display will normally indicate the exponent
of the current leak rate. For example, if the leak rate is 3 x 10
std cc/sec, the Leak Rate Bar Graph will indicate 3 while the
Numeric Display will indicate the number 7. The second
function of the display has been programmed to provide error
codes when a system fault has occurred (see Section 4.10 for a
list of error codes, their description and corrective action).
The display will indicate code EE while at the same time on
the Service Panel the Error Code indicator will be lit and the
Service Panel alphanumeric display will indicate the error
code.
A bar graph that displays the pressure at the test port. Scaled
for either millitorr or millibar. The test port pressure is also
displayed in digital format on the Service Panel Alphanumeric
Display.
During leak testing, this indicator will illuminate when the leak
measured is less than the programmed reject rate (or
maximum acceptable leak rate) and the unit is also in or below
the range of the reject value. The reject rate is set by the
user from the Service Panel (see Section 2.7).
