Full Flow Sensor Head Assembly
The sensor head assembly is attached to the vehicle exhaust in accordance
with the criteria in the SAE J1667 document. (The document describes the
different stack configurations and the placement of the sensor head).
Cable
The connecting cable is 25 feet long. Optional lengths of up to 50 foot are
available.
Control Unit
The control unit is operated by a membrane keypad, which consists of eight
tactile feedback push buttons.
The display is an alphanumeric LCD, containing 16 characters by two rows. In
low light situations, the display can be backlit. The display shows the prompts
the operator follows throughout the test sequence(s).
Up to 100 test can be stored in the system’s memory.
The RS232 connection permits an interface to a printer or CPU. The banana
jacks (red and black) allow a 0 –1 VDC output for a chart recorder.
Power
The meter is shipped with an AC Adapter/Charger which operates in 110V
(220V Export Version).
The 12 V sealed, lead-acid cell battery will allow up to 40 hours of
continuous operation with a full charge. This is reduced to about 20 hours, if
the display is backlit.
The time-out feature will turn the unit off automatically if none of the front
panel buttons are pressed for 20 minutes.
(See Appendix F to set this feature).
